Simcenter STAR-CCM+ vs. SimScale

The applications that I have been using it with in terms of flow and energy and temperature distributions and coupled solvers, segregated solvers, these kind of areas if you need that, those kind of solvers, it's very good. It's very robust. Maybe on the combustion side, it could improve, especially if you have these kind of tabulated solvers that you want to use, not the detailed chemistry, then it becomes very difficult to get some results from it. And do you trust the results or not? That's always the question on that kind of application, something that I could think of really fast.

SimScale has a quick learning ramp. This is due to the excellent staff at SimScale. I've had interns in their 2nd year of a BSME degree pick this program up and solve some difficult incompressible flow simulations. They love it and I love that we can iterate so quickly on a tool that doesn't stop their other design work. We can run a simulation and get back to designing in CAD. We get notified when the simulation is done. It's great! Give it a try for free and see for yourself.

• Meshing, for instance, it's very easy to mesh, try different approaches to meshing. Traditionally that's a very difficult job, but in STAR-CCM+ it makes it very easy and very reliable. Post-processing also is very nice and in all the modeling, the physics that you can carry out and you can simulate is also very, very nice. I tried to move to the priorities that does a good job. All in all, it's a very good software.

• Implementing physics like Cox-Voinov model
• Mesh related stability issues
• Chemical & plasma physics
• Integration with other products from Siemens (similar level as we have with Abacus)
• Speed up the lagrangian solver
• Improved guidence on uFluidics & evaporation models
• Interoperability (HEEDS, AMEsim, System Modelling Workbench but also with non siemens products and open source codes required for LBM, DSMC, PIC, DFT...

• Learning from tutorials is great, but limiting. The online help is a must.
• Some simulations take a lot of time, but at least it's not on your PC.
• Sometimes the software times out due to the server.

I had a great experience with SimScale but we only used the software for a short period of time to complete the current design requirements. It is not a software that we would continually subscribe to. Next subscription event would occur when there is a design requirement to do so.

Great single window GUI

Our designated support engineers do a proper job. On the outdated Help file and training material there is a lot to gain

It is super easy when it comes to implementing it.

We chose to go with SimScale based mostly on capital cost. Competitors have a large upfront cost and also require expensive hardware to properly run them. Even their subscription cost is competitive with the annual cost of others.

• Time saved in creating a inhouse code, tens and tens of hours.
• Time saved in experimental setup, tens of hours.
• Does add some time in testing to confirm star is doing what you think it's doing, but an overall net gain in productivity.

• We've been able to iterate through a large number of designs more quickly than we would have without a CFD simulation, and also compared to the time it would have taken to prepare most other CFD simulations.
• Affordable price, and it prevented us from needing to invest in expensive computing equipment.
• Help from the support team also sped up the process of modeling different scenarios!
