After looking around the forum, I found out that in order to increase the heap size, I have to edit the comsol.ini or comsolserver.ini file.

The problem I am having is, even though I have administrative rights of the computer where the comsol is installed, I cannot edit the file. This means, when I edit it and want to save the file, it says access denied.

Did anyone else have similar problem? Please let me know if you know why it is happening or how I could edit it.

thanks,

Hi,


Just copy the .ini file to another directory (say D: drive) and then edit and save it. You then copy this file back to the COMSOL directory. It asks you to overwrite the file, say yes.

I have also recently developed a significant problem with running out of Java Heap space, requiring a machine restart every few parametric runs -- a major pain.

Major symptom: "Error in multiphysics compilation" whenever evaluating the model.

I will try this.
