Altair HyperWorks vs. Simcenter STAR-CCM+

HyperWorks allows you to do structure analysis fast and precisely. Then, it also have the option of you to run optimization, Optistruct is a good solver and built in to the interface. The GUI sometimes can be overwhelming, because of it provides too much of features, it is pretty distracted and confused what will be the best option to perform analysis.

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.

Incentivized

• All-inclusive software suite
• Wide breadth of capabilities and custom scripting
• Highly efficient and scalable solvers/computation

Incentivized

• 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.

Incentivized

• User interface is improving, but not always intuitive; varies across tools
• Steep learning curve
• Cost may be out of reach for some, but relatively inexpensive if you need all the tools it includes (vs. paying for each tool individually)

Incentivized

• 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...

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 On the outdated Help file and training material there is a lot to gain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.

Incentivized

HyperWorks is far more capable than SOLIDWORKS Simulation offering more simulation solutions for more accurate analysis. The solvers are also more efficient so you get results faster and reduce time to market.

Incentivized

• An all in one solution keeps costs down if you need multiple analysis capabilities (FEA, CFD, MBD, etc.)
• Analysis work supports our other engineering/design work we wouldn't otherwise receive
• Fast and efficient solvers leads to higher throughput

Incentivized

• 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.
