Slow Mesh Conversion in Altair Inspire 2024 for Implicit Geometry

Hello,

I am currently using Altair Inspire 2024 for implicit modeling. My system specifications are: 2 RTX A5000 GPUs and an Intel Xeon Gold 6246R CPU (32 cores).

I have created an implicit geometry on a hollow cylinder, where the surface is modeled using strut lattices (octet structure). However, when I attempt to convert this geometry into a mesh, the process has been running for over 24 hours and is still not finished. My goal is to perform mode analysis. Upon checking, I noticed that the software is utilizing only 3% of the CPU and no GPU during the mesh conversion. I also tried selecting the mesh for print in the property editor.

Is there a faster or more efficient method to complete this mesh conversion process?

Thank you for your assistance.

    Hi Divij,

    Your structure does look quite complex so I'm not shocked that it takes a bit longer than usual, however 24 hours definitely seems off. Are you able to share the model so I can give it a try?

    I'd try it with large spacing first to clock how long it takes with coarse settings before stepping it down back to the settings shown here. 

     

    Hope this helps!

    Hey Adam,

    The file size is around 500mb. I can share it on the drive. May I please have your email-id?
    I reduced the spacing and mesh took around 2 hours. However, It still takes forever to simulate with SimSolid. The simulation is running for 2 days and is still stuck at 50 percent. I see in task manager that the software is only using 3 percent of the CPU. Is there a way to increase the resource usage?
