- Friday Flownex Tech Tips #13by Miles Adkins
Parameter Sheet Tricks
It’s Friday and time for the 13th Tech tip! Today we are going to go over some simple parameter sheet tricks and best practices. Parameter sheets are incredibly useful for running many different design or operation analyses. Let’s go over how best to utilize their functionality. In this example we’re working in Flownex version 126.96.36.19934
Parameter Sheet Setup
Probably the most critical thing to know when working with Parameter Sheets in Flownex is to make our edits through the setup interface. This is where we define the connection between Flownex and the worksheet.
As we recall, adding either inputs or results to our parameter sheet is as simple as dragging and dropping them into the different columns.
Renaming Parameter Columns
We may find that we’d like a more descriptive name of an input or result parameter than simply
“Pressure” or “Temperature”. We can rename the columns and this must be done via the parameter table setup. If we were to change the name in the worksheet it will be overwritten by the setup when the model is solved.
We may decide after creating a parameter table that we need to go back in and add a new column between existing input or result parameters. This should be done, again, through the setup. We will add our new parameter to the first open column and then move it within the setup.
*Important Note: Cell references in Excel are explicit in parameter sheets. If we are performing calculations in the parameter sheet using cell references and we rearrange columns these formulas will need to be updated.
- Don’t forget we can call global parameters in a parameter sheet!

Sizing Pumps and Manually Specifying a Pump Curve in Flownex
As a System Engineer you may not always already have equipment decided on for your particular network. Flownex makes it easy to start from scratch and will help determine the equipment necessary to meet the flow or process requirements. In today’s tip we’ll go over how to size a pump using the basic centrifugal pump component and how to manually enter pump curve data. We are using Flownex version 188.8.131.5234
Sizing a Pump
In our example scenario let us pretend we are sizing a pump for a cooling water circuit. We are tasked with finding a pump which will deliver water at a rate of 1 kg/s to the heat exchanger. We know our upstream and downstream boundary conditions as well as the heat added at the exchanger and the speed at which we will be operating the pump.
Choose the appropriate flow component
There are a few different pumps available in Flownex:
Basic Centrifugal Pump: Used when we do not have a pump chart available, particularly useful when sizing a pump.
Fan or Pump: Used when a pump chart is available for modeling either compressible or incompressible flows.
Positive Displacement Pump: Used for modeling rotary and reciprocating pumps where the fluid is incompressible, non-Newtonian, or a slurry.
Variable Speed Pump: Similar to the Fan or Pump but with the ability to interpolate between fan/pump curves for different speeds of rotation.
In this case we’d choose the Basic Centrifugal Pump. This is found in the component pane under Turbos and Pumps. Since we only know the RPM we can enter it in the inputs under Speed at BEP:
Recall we don’t know what the design of the pump will be. Since all we know is that the mass flow rate needs to be 1 kg/s we will check the box for fixed mass flow and then select to change design to target our desired flowrate.
Once we hit solve our pump design inputs will be populated such that our desired mass flow rate is achieved. We can cross-reference these values with available pumps to choose the appropriate component for our network!
Specifying a Pump Curve
If we already know which pump we are using, or perhaps are trying to decide between several available pumps, we may need to add these pump curves to Flownex. To add a pump curve we will navigate to the Charts and Lookup Tables pane > Project Database > Flow Solver > Turbos and Pumps. In this scenario we are looking at a single speed pump so we will right-click on Pump and Fan Charts and Add a Category.
We can name our category whatever is appropriate and then right-click on the newly created category to add our own pump chart.
To edit the newly created pump chart we can either double-click on it or right-click and select edit. Now we simply specify the Reference Density and then fill out the table with the relevant data points. To speed things along we can copy and paste a table of data points from excel or whatever source we get this curve from. Don’t forget to check your units!
Girl Gang Garage: Custom Car Rebuilds + 3D Scanning + 3D Printingby Pam Waterman
- Don’t forget you can save created pump charts in a shared database (see previous blog post on creating a shared database)
What do you get when you cross a 1961 Volvo PV544 retro-look car with a sleek 2019 Volvo S60 T8 Polestar Engineered sedan – and why would you ever do that?
You get a custom head-turner hybrid vehicle designed to get people talking, especially about women in automotive trades. That’s because this blended vehicle project is being disassembled, redesigned and rebuilt by an all-female team based at Girl Gang Garage in Phoenix Arizona.
Girl Gang Garage founder and co-owner, Bogi Lateiner, TV host of Motortrend’s All Girls Garage and Garage Squad shows, is well on the way to transforming these vehicles as the third major public project she has undertaken. Along with co-owner Shawnda Williams, Lateiner offers women of all ages, experiences and skill levels the chance to lend a hand, learn a tool, and possibly discover a new career-path in the automotive trades.
Lateiner and Williams apply well-honed old-school skills but have been increasingly interested in the possibilities offered by today’s digital workflow. That’s why early in 2021, after conversations with the fellow re-build team at Kindig-It Custom Car Fabrication, Lateiner reached out to Stratasys to see how they might work together to incorporate 3D printing in the PV544 project.
At Stratasys, Pat Carey, Senior Vice President Americas Products & Solutions, and Allen Kreemer, Senior Strategic Applications Engineer, were immediately onboard with the chance to help Girl Gang Garage move into the digital world while widening their circle of women with automotive skills and interests. They loaned the team an F370 FDM 3D printer and accompanying support-removal SCA tank and offered to supply filament material for a two year try-whatever-you-want time period. Moreover, they pulled together a volunteer team of women across the country who could support the effort on multiple fronts.
A Virtual Team and a Digital Workflow
The team includes engineers whose day-time jobs have them working at Stratasys, Link3D, Autodesk, Xerox, Collins Aerospace and Ford Motor Company or as independent consultants. Printer installation and local support is handled by PADT Inc, a Stratasys reseller and 3D printing/design/simulation company located just 16 miles away from Girl Gang Garage. In addition, members of Women in 3D Printing offered to coordinate many of the publicity efforts and even sponsor a related design competition targeted at young women in high schools and colleges who are learning CAD skills. (More on that to come.)
During the first few Zoom meetings that introduced Lateiner and Williams to the technical capabilities of the different team members and the printer, the basic rebuild plan was presented: strip the PV544 down to bare metal (removing every mechanical and electrical component), disassemble the S60 down to the chassis, engine, drive-train and hybrid motor system, and figure out how to make the two sections fit!
Traditionally, that workflow depended strictly on the classic tools of the trade, from cutting wheels and a Sawzall to hand-grinders and pneumatic drills. Those components are still coming into play on the current project under the skilled eye of the Girl Gang Garage leaders, but now complementary digital processes are being added.
It Starts with Scanning
PADT recently became a reseller of GOM 3D scanning hardware and software tools, and the timing was perfect to bring the new handheld Tscan Hawk system on-site. Operating with both red-line and blue-line (different wavelength) laser scanners plus stereo cameras, the Tscan Hawk captures millions of spatial 3D-point-coordinates (termed clouds of data) which are converted into a standard STL mesh file format for several end-purposes. The red lasers generate measurements across medium to large surfaces while the blue-wavelength sensors capture fine detail, with accuracy down to 20 microns.
GOM Inspect software records reference points, captures the individual coordinate data and allows interrogation of that data to provide dimensions, such as the distance between the engine frame mounts or the diameter of the hole into which the headlamp fits.
These three images show a) the reference-point data that appears on the laptop screen as the shape of the PV544 vehicle’s underside is captured, b) the completed scan showing the 3D details of the as-built sheet metal and c) a report page from GOM Inspect software with dozens of dimensions extracted from the scan, such as the length of the trunk opening and the width of the opening available for the engine mount. The scan data, if exported as an STL file, could be sent directly to a 3D printer – though for this project the team is not printing the full body. Instead, subsets of the scan are being used for reverse engineering, where the data works as the basis for creative design elements to be printed and perhaps painted or plated.
To do so, the scanned data is be brought into a surfacing package such as Geomagic Design X or Innovmetric PolyWorks. Those software tools let users convert the STL mesh into an IGES surface, which can then be brought into a CAD package as the basis for a new solid model.
Not for the real build but as a fun example, here is a possible headlight-rim with the letters “Girl Gang Garage” cut out as a circular repeat pattern, that could be backlit with LEDS to customize the build. The design and dimensions are based on the maximum inscribed circle fitted by the GOM Inspect software inside the given opening. (In future blog posts, we’ll show examples of the CAD team’s actual 3D printing results.)
Scanning has many other purposes and capabilities. If CAD data were available for the actual vehicle, those files could be imported, overlaid on the captured data, and compared, alerting the user to deviations between intended and actual dimensions – a very common use of GOM Inspect software.
Every Thursday through Sunday, volunteer women come to Girl Gang Garage and learn to use cutting tools, welders, sanders and more, making daily progress toward the completed hybrid PV544. (All women are invited to come help and learn, at no cost – just sign up to get involved and get yourself to Phoenix.) Here are a few glimpses into the work as of early April – much more has been done but stay tuned for the next blog post as we show off elements of the S60 sedan, scan data being used for reference, and details of the design contest.

How to use Flow Path Graphs and Increment Plots in Flownex
Flow Path Graphs and Increment Plots can be incredibly useful visualization tools to see how a simulation result varies as a function of length along the axial flow path and to see a higher fidelity result for a single flow component. Use these in Flownex to up your reporting game! In this demo we are using Flownex version 184.108.40.20634
Creating a Flow Path
A flow path is any continuous series of flow elements and can be created by clicking “Flow Paths” in the results ribbon. Once we’ve created our new flow path we define it by choosing our start and end nodes.
Another, simpler, method is to simply drag and drop the nodes onto the flow path start and end point:
If we have a branched network we can add an intermediate node or flow component to our flow path to ensure the correct path is captured in the graph:
Insert a Flow Path Graph
The Flow Path Graph is in the component pane under visualization > graphs. Once the graph is added to the canvas we simply need to drag and drop our newly created flow path onto the graph and choose the characteristic we are interested in plotting. We will need to drag and drop the flow path for each characteristic we would like plotted.
How to create Increment Plots
You may have noticed in the previous images that there were many data points on the graphs for each of our flow components. This is because we had each pipe modeled as 25 increments. When we add increments to our flow components Flownex will treat each component as if it were split up that number of increments – solving the conservation equations for each increment rather than once over the entire component. This is helpful when modeling long pipes, capturing pressure waves, or determining exactly where a phase change may happen. A good way to think about this is that it is essentially the same as refining a mesh in a typical finite element analysis.
There is another plot in Flownex we can use for a single flow component that has been incremented. The increment plot is located in the components pane under Visualization > Graphs > Increment Plots. If we were, for example, trying to plot the inside surface temperature of our first pipe in this example network we could use an increment plot to see what is going on.
To create an increment plot we simply drag and drop the plot onto the canvas. We can either selectively drag results from individual increments or multi-select many increments and drag the desired variable onto the graph. Note that since there is a tie of each increment parameter separately there may be some delay if we are multiselecting a very large number of increments.
- We can use a Flow Path graph for a single component to avoid having to multi-select increments.
- To create a graph on its own page instead of floating on the canvas go to the Project Explorer pane on the left side of the GUI, select Graphs, then right-click on the Graphs Folder and select Add Graph Page and choose your desired type of plot.
