ANSYS Discovery Live – Fluid Flows Webinar Recording & FAQ

Below you can find some of the most frequently asked questions from this webinar, along with our answers.

Q: What computer and license type are you actually using for running the simulation? Ram, cores, CPU, etc.

A: 16 GB RAM Intel i7, NVIDIA Quadro K1100M

Q: Is the solver running a transient solution in the background while you are post processing and haven’t paused it, or is it marching towards better convergence of a steady state solution?

A: The solver is running a transient solution the entire time. The only time it is not doing this is if I pause the simulation.

Q: Does this require 3D models to be built within Discovery Live, or it can import outside 3D models (Solidworks etc) and still allows the user to add/modify geometry objects on the fly within Discovery Live?

A: Yes, you can import any CAD native format or neutral format in Discovery Live. You can also create Geometry from scratch in Discovery Live using the SpaceClaim tools.

Q: It looks like when you change the “speed – fidelity” setting, the solver resets; while when you change other settings (like domain geometry), the solution continues from last step. What’s being changed when you change the “speed-fidelity” setting?

A: When you change the Speed-Fidelity setting, the computational grid of the domain is coarsened or refined. It is also re-partitioned/parallelized on the GPU cores.

Q: Are there predictive features of simulation, obtaining design suggestions from the end results? Are there inputs for end results to accomplish reverse engineering?

A: Yes, in a sense. Because Discovery Live provides literally “real-time” feedback on design changes, you have design suggestions based on the end results. For reverse engineering in Discovery Live: there are not inputs for end results, but the part you’d like to reverse engineer can be imported (or created) in Discovery Live, and then analyzed in the range of operating conditions to understand it’s performance.

Q: Do you have any control of the mesh? How boundary/layer effects can be checked?

A: Control of the mesh available via the Speed-Fidelity slider bar. Boundary layer effects could be checked using surface integrals of force, but again recall that if you’re trying to finely resolve details such as boundary layer physics, you may need to consider the next level of accuracy which would be Discovery AIM or Fluent.

Webinar: Additive Manufacturing & Simulation Driven Design, A Competitive Edge in Aerospace

PADT recently hosted the Aerospace & Defence Form, Arizona Chapter for a talk and a tour. The talk was on “Additive Manufacturing & Simulation Driven Design, A Competitive Edge in Aerospace” and it was very well received.  So well in fact, that we decided it would be good to go ahead and record it and share it. So here it is:

Aerospace engineering has changed in the past decades and the tools and process that are used need to change as well. In this presentation we talk about how Simulation and 3D Printing can be used across the product development process to gain a competitive advantage.  In this webinar PADT shares our experience in apply both critical technologies to aerospace. We talk about what has changed in the industry and why Simulation and Additive Manufacturing are so important to meeting the new challenges. We then go through five trends in each industry and keys to being successful with each trend.

If you are looking to implement 3D Printing (Additive Manufacturing) or any type of simulation for Aerospace, please contact us (info@padtinc.com) so we can work to understand your needs and help you find the right solutions.

 

Assembly Modeling with ANSYS

In my previous article, I wrote about how you get what you pay for with your analysis package.  Well, buckle up for some more…but this time we’ll just focus on handling assemblies in your structural/thermal simulations.  If all you’re working on are single components, count yourself lucky.  Almost every simulation deals with one part interacting with another.  You can simplify your boundary conditions a bit to make it equivalent, but if you have significant bearing stresses, misalignments, etc…you need to include the supporting parts.  Better hope your analysis package can handle contact…

Image result for get what you pay for

First off, contact isn’t just for structural simulations.  Contact allows you to pass loads across difference meshes, meaning you don’t need to create a conformal mesh between two parts in order to simulate something.  Here’s a quick listing on the degrees of freedom supported in ANSYS (don’t worry…you don’t need to know how to set these options as ANSYS does it for you when you’re in Workbench):

image

You can use contact for structural, thermal, electrical, porous domain, diffusion, or any combination of those.  The rest of this article is going to focus on the structural side of things, but realize that the same concepts apply to essentially any analysis you can do within ANSYS Mechanical..

First, it’s incredibly easy to create contact in your assembly.  Mechanical automatically looks for surfaces within a certain distance from one another and builds contact.  You can further customize the automated process by defining your own connection groups, as I previous wrote about.  These connection groups can create contact between faces, edges, solids bodies, shell bodies, and line bodies.

image

Second, not only can you create contact to transfer loads across different parts, but you can also automatically create joints to simulate linkages or ‘linearize’ complicated contacts (e.g. cylindrical-to-cylindrical contact for pin joints).  With these joints you can also specify stops and locks to simulate other components not explicitly modeled.  If you want to really model a threaded connection you can specify the pitch diameter and actually ‘turn’ your screw to properly develop the shear stress under the bolt head for a bolted joint simulation without actually needing to model the physical threads (this can also be done using contact geometry corrections)

image Look ma, no threads (modeled)!

image

If you’re *just* defining contact between two surfaces, there’s a lot you simulate.  The default behavior is to bond the surfaces together, essentially weld them closed to transmit tensile and compressive loads.  You also have the ability to let the surfaces move relative to each other by defining frictionless, frictional, rough (infinite coefficient of friction), or no-separation (surfaces don’t transmit shear load but will not separate).

image

Some other ‘fancy’ things you can do with contact is simulate delamination by specifying adhesive properties (type I, II, or III modes of failure).  You can add a wear model to capture surface degradation due to normal stress and tangential velocity of your moving surfaces.  You can simulate a critical bonding temperature by specifying at what temperature your contacts ‘stick’ together instead of slide.  You can specify a ‘wetted’ contact region and see if the applied fluid pressure (not actually solving a CFD simulation, just applying a pressure to open areas of the contact interface) causes your seal to open up.

image

Now, it’s one thing to be able to simulate all of these behaviors.  The reason you’re running a finite element simulation is you need to make some kind of engineering judgement.  You need to know how the force/heat/etc transfers through your assembly.  Within Mechanical you can easily look at the force for each contact pair by dragging/dropping the connection object (contact or joint) into the solution.  This will automatically create a reaction probe to tell you the forces/moments going through that interface.  You can create detailed contour plots of the contact status, pressure, sliding distance, gap, or penetration (depending on formulation used).

image

image

Again, you can generate all of that information for contact between surface-to-surface, surface-to-edge, or edge-to-edge.  This allows you to use solids, shells, beams, or any combination you want, for any physics you want, to simulate essentially any real-world application.  No need to buy additional modules, pay for special solvers, fight through meshing issues by trying to ‘fake’ an assembly through a conformal mesh.  Just import the geometry, simplify as necessary (SpaceClaim is pretty awesome if you haven’t heard), and simulate it.)
