Can Anyone Solve the Virtual Memory Issue in COMSOL?

Click For Summary
SUMMARY

The discussion centers on the persistent virtual memory issue in COMSOL, specifically in the 64-bit version. Users report that COMSOL utilizes more virtual memory than available RAM, even when there is significant unused RAM (25Gb). Despite attempts to seek solutions through forums and tech support, no definitive fix has been provided, particularly for users without active subscriptions for support.

PREREQUISITES
  • Understanding of virtual memory management in software applications
  • Familiarity with COMSOL Multiphysics software
  • Basic knowledge of system memory (RAM) and its utilization
  • Experience with troubleshooting software issues
NEXT STEPS
  • Research COMSOL Multiphysics memory optimization techniques
  • Explore user forums for potential workarounds regarding virtual memory settings
  • Investigate the implications of using 64-bit applications on system memory
  • Learn about contacting technical support for software troubleshooting
USEFUL FOR

This discussion is beneficial for engineers, researchers, and technical professionals using COMSOL Multiphysics who are experiencing memory management issues and seeking effective solutions.

I have been asking for years how to fix the virtual memory issue in COMSOL. I have 32Gb of memory, and it will use more virtual memory than RAM when there are at least 25Gb of RAM unused. Does anyone have a fix for this?

I'm using 64 bit COMSOL

I've seen it addressed in their forums, but nobody seems to have solved it. I do not have support for comsol under an expired subscription. So, no.
