COMSOL with MATLAB leaking memory

Hi everyone,

I'm having memory issues when using COMSOL LiveLink for MATLAB. Essentially I'm solving the same simulation with varying parameters in a for loop while because I'm intrested in some parametric dependence. Unexpectedly, as the simulation is running the memory usage slowly piles up. Even after clearing the workspace (clear all, clearvars, clear -global), the program comsolmphserver.exe is still consuming a lot of memory. The same script didn't give this problem with 5.2a, it began when I started using 5.4

Is there any way to release this memory? Thanks in advance

Hi Andrea

Installing the latest update should help.

If that doesn't help then please send your model to support and we'll see what we can do to help.

Hi Lars,

Thank you for your help. Updating didn't work but I found another thread on this forum ("Memory Usage Increase With Looped LiveLink For MATLAB") from someone having the same problem I was facing.

The solution you suggested was to lookup the knowledge base entry: https://www.comsol.eu/support/knowledgebase/1264

...and it worked!

Thanks again,

Andrea
