Occasionally glossed over, adding custom fluids is a fairly standard operation in Flownex that we don’t think about until it’s necessary. There are a couple of ways to do this which we’ll go over in today’s post. I am working in Flownex 8.12.7.4334.
Creating a mixed fluid
To create a mixed fluid we first need to create a folder for this fluid in our project database. This can be done in the charts and lookup tables pane by right clicking on “mixed fluids” and selecting “add category”. We can create our new fluid by right-clicking on the new folder and selecting “Add a new mixed fluid”. Note we can right-click and rename both the fluid itself and the containing folder.
To define our new mixed fluid we double-click on the new mixed fluid to open the editor. Here we can add the components of our mixed fluids.
Creating a new fluid from scratch
To create a fluid from scratch we repeat the same process of creating a folder and creating a new fluid as above with the exception being that we’d complete these steps under the “Pure Fluids” category. Once this is done we’ll need to double-click or right-click > edit our from scratch fluid and enter in the fluid properties. Note for many properties we can define the relationship with pressure and temperature as constant (non-dependent), table, equation, or script.
Importing a fluid
To import a fluid we will follow the same steps of creating the folder under pure fluids. Now instead of right-clicking and adding new we will right-click and select “import”. Then we simply navigate to our desired fluid file and click “Ok”.
Bonus Tips!
In the window where you define your fluid you’ll notice the “Test” button. This feature can be utilized to test created fluids to confirm properties against known properties for given pressures and temperatures.
We can also copy and paste fluids from the master database into the project database to give us a good starting point for creating similar fluids (or extending properties to higher/lower temps/pressures).
The result layers in Flownex have evolved quite a bit over the last few iterations of the code. Although we might typically associate color-gradient results more with 3D CFD, it does have a place in 1D system modeling. Taking advantage of results layers in Flownex can give a very quick understanding of what is going on with our system, and, with a little customization, can be incredibly powerful as an addition to our design and analysis toolbelt. In this post I am using Flownex version 8.12.7.4334.
How to create a result layer
To create a custom result layer we must navigate to the results ribbon and select result layer setup.
First we want to right-click in the Result Layers window and add a new result layer.
There are two options to add the schema for our result layer. The first is to right-click on the Selected Result Layer Schemas and add either a specific or generic schema. The second, and my PREFERRED, method is to simply drag and drop results from components on the canvas into this window:
Note that I want to multi-select any component types which will be included in this result layer. This could be any flow components which share a common result such as “quality”. I also convert to generic because I want the result layer to apply to all pipes, not just the pipe I initially drag and drop the property from.
Defining the custom result layer
In this example I have a two-phase water network with a cold external temperature. I want to create a result layer to quickly see if the water is in the gas phase, liquid phase, or somewhere in-between. The problem I have been tasked with solving is ensuring that the water never condenses. I will need to determine where we may need to add additional heat flux to the network.
We can use the Quality result property to determine the phase of our fluid. Quality < 0 indicates fully liquid, quality between 0 and 1 indicates liquid/gas mixture, greater than 1 indicates fully vapor.
To make this work as intended I can set up a gradient with three increments going from -1 to 2. The idea being the lowest increment would encompass -1 to 0, middle increment would be 0 to 1, and the top increment would be 1 to 2. For the gradient mode I made sure to pick <-[MinValue, MaxValue]-> so that the max and min increments would extend past the specified range.
As we apply this to our network we can easily see that we do, in fact, have a phase change from gas at the inlet, to mixture in the second two component, to fully liquid near the outlet.
I may decide to add a heater to our outlet pipe and perhaps a thicker insulative layer to all three to attempt to keep the water in gas phase throughout the system.
Bonus Tip!
Result layers can also be super handy when troubleshooting to quickly identify large pressure differentials, choking points, or other outlying fluid properties.
Compound components make it easy and efficient to reuse the same collection of components over and over throughout your models. In this post I’ll be going over the basics of making a user-friendly and aesthetically pleasing compound component. In this example I am working in Flownex Version 8.12.7.4334
How to create a compound component
To create a compound component we must first create a local library in the project database. This can be done by right-clicking on the project database in the components pane and select “New Library”.
We can name our new library and choose a picture if desired:
To create our compound component we just need to right-click on the new library and select “New Compound Item”
To build our compound component we’ll use the “edit” function on the compound component. In this example I am building a Lohm resistor component. It’s a good idea to test my component on a separate page to make sure scripts interact as expected and validate results against some given test cases.
Let’s make it functional!
To define the inputs and results we’d like to expose to the user we right-click on the new compound component in the library and select “component setup”.
To add inputs and results we need to navigate to the Compound Setup ribbon and then simply drag and drop inputs and results into the Selected Properties window. Note that we can even grab whole categories of inputs or results to save time!
Now those inputs and results will appear to the user when they add this compound component to their canvas!
Let’s make it pretty!
To make our component more aesthetically appealing let’s replace the boring default icon with one more representative of our Lohm Resistor. To do this we right-click on our compound component again and this time stay in the “Display Setup” tab. We can click the “Choose Picture” button to upload our own icon. To refresh on the image selector check out the blog post on adding a background image.
To correct the aspect ratio so that it shows up looking less squished on our canvas we want to change the settings back in the Compound Setup tab. I’ll change it to 133×34 so that it appears similar in scale to the standard flow components but correct in the aspect ratio.
Now when we place our compound component onto our canvas it should look great!
Bonus Tips!
In the compound component setup there is a third ribbon called “Tooltips Setup”. This is where we can define what properties show up when we hover our mouse over the component.
Don’t forget we can save compound components in a “database” on a server so that they can be accessed by every Flownex user in your organization.
As we build more and more networks it quickly becomes tedious to enter in the same inputs many times. There are a couple methods of using global parameters to save us lots of time and clicks. In this example I am working in Flownex Version 8.12.7.4334
Refresher on Global Parameters
Global parameters are just what they sound like. Parameters defined globally for the project. These could be any type of component input; diameter, length, temp, pressure, etc.
The global parameters can be found in a couple of locations. Under the configuration ribbon we can open the global parameters in a floating window which gives us a friendly interface for creating or modifying these parameters. To create a global parameter one may simply right-click in the GlobalParameters window and select Add (hint: there’s a better way!).
Conventional method to add Global Parameter
Global parameters can also be accessed in via the solver tab in a similar way to typical inputs (this is important later on).
Access via Solver Tab
The Quick way to add Global Parameters
We don’t really want to have to navigate to that configuration ribbon, right-click a bunch, choose names and assign units do we? Good news! There is a much faster way to add a global parameter. We can add a global parameter with minimal work by simply typing a dollar sign “$” prefacing the name of the tag in any of our component input fields! Remember to hit enter after typing the identifier.
Global Parameter Shortcut
Once a global parameter has been defined we can tie more inputs to the existing parameter by typing the dollar sign “$” and choosing the correct parameter from a drop down:
Multi-Assign Global Parameters
As you can see, this can be quite a time saver when building a network! The next trick utilizing global parameters will have to do with using them for actual analysis.
Using Global Parameters as Manipulatable Inputs
The default/slow way to change a global parameter would be to go to the configuration ribbon > global parameters, and manually change the value in the floating window. No thanks. This is not automated at all and requires many clicks.
The better way to utilize the global parameter as an input would be to tie the global parameter to an input sheet, parameter table (for a parametric study), or even a human machine interface component (HMI).
Global Parameters in Input Sheet
For a design variable that an analyst or engineer may change which would then remain constant (such as pipe diameter) the input sheet comes in very handy. To reference a global parameter in the input sheet recall the second method to access the global parameters and then simply drag and drop onto the input sheet:
Global Parameter in Input Sheet
Global Parameters in Parameter Table
If you are trying to run a parametric study where you are varying something like ambient temperature, it makes sense to use a global parameter as you may have many boundary conditions defined by a single global parameter. Similar to the input sheet this can be tied to a global parameter by a simple drag and drop operation:
Global Parameter as variable in Parameter Table
Global Parameter in a Human Machine Interface
By now I expect you are catching on. The trick to defining a global parameter externally is to use the second method; solver tab > global parameters, and then drag and drop to your desired connection. In the HMI instance I’ve tied inlet mass flow to a Track Bar so that a user can dynamically change the flow rate during the solve:
Global Parameter tied to HMI
Global Parameters and HMI components
Global Parameters are efficient and POWERFUL
We can use global parameters during network construction using the “$” shortcut to build our networks much more quickly and keep identical inputs the same. We can tie these global parameters to other tools to keep our user inputs all in one place, reducing clicks, and reducing the chance of forgetting to update an input.
Bonus Tips!
Global Parameters can also be used in Designer so that you can keep your independent to dependent variable count the same (EX: Adjusting ALL pipe diameters to target a single exit flowrate)
Global Parameters can be adjusted via transient actions (EX: Adjusting ambient temperature to model the changing temperature over the course of 24 hours).
In this post I will go over what is usually the first step in any Flownex network I build. Adding a background image not only helps me lay out my network but also helps colleagues and clients understand networks at a very quick glance. In this example I am using Flownex version 8.12.7.4334
Choosing an Appropriate Image
The first thing we want to do is to make sure that the image size is such that it’s reasonable in size both resolution-wise (so it doesn’t appear pixelated), and right-size so that components don’t appear too small when placed on top. I recommend something in the multi-thousand of pixels both in width an height. 3000 pixels at a minimum. I usually shoot for around 10,000 wide by 5,000 high if the background image will be landscape. For very complex, large networks, it may make sense to go much larger.
Once we’ve found an appropriate image we will want to make a note of the exact size. This can be found by right-clicking on the image file, selecting properties, and navigating to the details tab.
Confirming Image Resolution
Resizing Flownex Canvas
The canvas in Flownex can be resized to match this resolution by right-clicking on the canvas, selecting edit page, and populating the correct inputs:
Editing Canvas Inputs
Applying Background Image
The background image can be applied by clicking the radio button next to Style in the Appearance subcategory. Here we will change the Fill Style type to Image, then click the Select Image button:
Styles Editor
The images saved locally to this project will appear here. To add an image we simply click Add Image, navigate to the image of our choice, and click open. Now that it is available as an option we select the image in the Image Selector Gallery and click OK.
Image Selector Gallery
We can press OK in the Styles Editor to confirm our changes and we should now see our added image as the new background!
Drawing Canvas with Background Image
Bonus Tips!
Adjusting the Fill Style opacity can fade out the background image so that it doesn’t overwhelm the Flownex components placed on top.
Turning off the grid under the View ribbon can make the canvas a bit more aesthetically pleasing.
ANSYS Discovery is a wonderful tool for fast and first look structural, fluid flow, and thermal simulations. Discovery gives us the ability to modify geometry very quickly within the interface and to add or remove features to view realtime simulation reactions. This allows us to quickly iterate, explore design changes, and better understand interaction between our design and the environment. Today we are going to be investigating the pressure profile on the exterior of a travel trailer being pulled behind a truck down the highway.
Truck and Trailer with velocity streamlines
In this analysis we are using a 2018 Chevy Silverado 2500 model pulled from GrabCAD with a generic 25 foot travel trailer. Based on described experience we’ve noticed that the roof and sidewalls of a moderately sized travel trailer seem to bow outwards at highway speeds near the front of the trailer.
The first thing to do is to put this model in an enclosure and prescribe a flow condition at the inlet and a pressure boundary at the outlet. Modeling the truck/trailer combo at a speed of ~55 mph (25 m/s) confirms that there is suction (negative pressure) present in these key areas:
Negative Pressure: Truck and Trailer in 25 m/s airflow, -500 Pa isosurface
While the actual roof and sidewall separating could be attributed to poor manufacturing processes we wonder if there could be a design change to minimize negative pressure/suction. One idea would be to incorporate some sort of turbulator to break up the laminar flow. I’ve seen turbulator tape in a zig-zag pattern used in aviation for this specific purpose so we’ll try recreating the travel trailer equivalent and see how it goes.
I started with a zig-zag pattern about 4″ tall on top of the trailer to see if I could “pop the bubble”
This did have the intended consequence and it was curious to see how much impact the turbulator on top of the trailer had on the negative pressure at the sidewall of the trailer:
The next thing I wanted to try was moving the turbulator forward or backward to see the effects. Moving the turbulator towards the aft of the vehicle has limited effects but moving it to different locations within the suction “bubble” seems to effect our -500 Pascal isosurface:
This would seem to indicate the presence of a “sweet spot” for turbulator location that merits further research in either the “Analyze” mode within Ansys Discovery or within Ansys Fluent.
Before I hang up my coat I’d like to investigate one alternate design that I’ve seen more often in automotive applications. I’m going to try adding vertical pillars and see how that goes:
We can easily change the height and position of the pillars to see the resultant effects on the pressure isosurface. The pillars also have a significant effect on the suction bubble but I notice that it has less effect on the suction on the sides of the trailer.
Using Discovery we can quickly and easily iterate on designs, get a first-view of the physics, and determine which change or design merits further investigation. In this analysis we can see that there is most definitely a suction profile at the front of a generic travel trailer. If the suction proves damaging we can see that there are several design changes which will help to mitigate this effect.

This post was created based on the expert advice of PADT CFD engineer and Project Lead, Nathan Huber.
Simulating the behavior of liquids and gases has become a standard part of product development in products where fluid behavior plays an important role. Here at PADT, we have been using Computational Fluid Dynamics, or CFD, for years to model everything from combustion in turbine engines to cooling of electronics, to golf balls. With that experience, our estimates for a given project have become reasonably accurate.
However, we can only estimate accurately if we have complete and accurate information on what you need simulated and what you hope to gain from the simulation. To help everyone arrive at more accurate cost and schedule estimates, even if you are planning a project internally, we offer the following list of five questions we always ask:
1: Have we signed a Non-Disclosure Agreement (NDA)?
Before we can do anything, we need to have an agreement in place that clearly defines how both sides handle proprietary information. When we have tried holding meetings to gather information for a quote before an NDA is in place, we almost always waste time. There is just too much that is proprietary in most products.
2. What does your CAD Geometry look like?
We also need to know the physical geometry of your system. That is why we ask for an accurate and
complete CAD model. We take some time to
poke through the files in our software to make sure we can use the geometry, it
is accurate, and it has the level of detail required for CFD. Basically, we check
to see if we can pull a fluid domain from your CAD models. Remember, we are not
simulating the solid part of your product; we are modeling the inverse and
therefore need to pull a negative volume from your geometry.
3. What are the Boundary Conditions and Material Properties?
Now that the geometric domain is understood, we need to know
what is inside that domain, and what is acting upon it. We will ask you for boundary conditions, and
for the material properties of the fluid or fluids you are asking us to
model. The complexity, time variation,
and severity of the loads drive the difficulty of setting up and running the
simulation. And the material properties can also impact the sophistication of
the model as well as its robustness.
Both, therefore, have a significant impact on cost.
4. What results do you want to see?
When
a simulation finishes, it can be post-processed to get a vast array of plots,
figures, animations, pretty pictures, etc.
Those take time to create, so we need to know what you want to see. Also,
we set up some post-processing parameters before we start the simulation.
5. What do you want to learn from your CFD Simulation?
The whole point of doing a CFD simulation is to study the behavior of your system. We need to know what behavior you need to understand so we can make sure that the simulation we propose answers your questions and guides you in your design process.
We hope you find this review useful when you are planning your internal CFD project as well as those you outsource. And speaking of outsourcing, please consider PADT as your resources for any future simulation projects of any type, not just CFD. Now, you already know what questions we will ask.
