Simcenter STAR-CCM+ vs. uCrowds

For my personal use case, I found that STAR CCM+ was extremely easy to use, learn, and set up cases for Lagrangian particle tracking cases. Each option was easily found, and parameters to fine-tune the cases were very simple to execute. I had to create a custom field function with a nested If-else loop to account for particle capture on the filter media surface. Setting this up was very easy, and the reference material provided by STAR CCM+ was helpful. Sometimes, on the older version of STAR CCM+, when visualizing the volume mesh, some cells tend to disappear; this shows up even when plotting contour plots on the same section plane. This is improved in the newer version of STAR CCM+.

• Meshing is very easy to do in STAR CCM+
• Post-processing results is also very intuitive, making extracting results very enjoyable and easy to use.
• The Advanced rendering options that are available in STAR CCM+ can really help make very well-generated videos that can make the simulation easy to visualize, share with non-technical engineers, and showcase the study done.

• 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...

STAR CCM+ technical support was very quick to respond when a ticket was raised for issues. For support in setting up a test case for the Lagrangian particle tracking technique, a support assist agent was assigned immediately, and after having a detailed discussion, my problem was understood by them, and a suitable test case was shared, which I was able to understand and use to build my case.

It is super easy when it comes to implementing it.

Competitive tools, both Fluent and STARCCM+, but the user interface and ease of learning, along with everything in a single interface, and a wide variety of proven physics capabilities, along with good scalability and automation, made the choice easy for me. Also, the user guide and tutorials available to explore various kinds of Physics capability, and A single license for access to all physics, also made it easy.

• I can't think of anything but positive of course. I mean, we've been improving our products, we've been using this to test less to make sure that our products will meet the requirements and meet the objectives that we have. And I've never seen a case where it has been proven otherwise. So yeah, it's been great for us.
