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.

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 have a solid that is heating a gas. The heat transfer module for the solid has convective cooling with the faces of the boundaries between the gas and solid selected, and the fluids module has convective cooling with the same selected boundaries. I thought if I put convective cooling in both...

Use the heat transfer module to do generate the temperature profile of the tube. Specify a heat source (find the power density W/m^3). Then couple the fluids module with the heat transfer module. There is a plot to plot the temperature of the fluids (T2 if fluids is the second module)...

I figured out that it is okay if you don't see the moving mesh.

I'm using COMSOL 4.0a. Whenever I apply a free tetrahedral mesh, I can see it on the structure immediately. However, now I need to use a moving mesh to combine the results of structure deflection and fluid flow. I cannot get the solver to compute without errors. Am I supposed to immediately...
