Yes, that is no problem.

If you are using a 32 bit Windows system a single process cannot use more than 2 GB RAM. You can set the /3GB switch in win.ini I think. But 3GB is then the limit. I tried that once and it made my PC instable.
If you want to use more RAM you must switch to a 64 bit system.

Thanks Edgar...

Is it possible to open a file (made in COMSOL 4.3a installation compatible with 32 bit) on 62 bit installation??

Hi

basically either get more RAM, or reduce the mesh density: use symmetry (model 1/2 or 1/4 ... if possible), use 2D instead of 3D. Even if simplifications by symmetry is not always possible, often one can simplify the geometry, but this require some "engineering" insight in the solution to decide what is or not relevant.
with my 48GB of RAM I can solve problems of 2-4 MDoF but there are many DoF per element, all depends on the physics and discretisation being used

Good luck

Thank You Ivar...

I am currently working with 2GB RAM. I suppose that I can try with 4GB RAM!

Problem with meshing

Sir,

While meshing my model, I am getting an error message as follows "Out of memory for mesh processing". What does that error mean and what are the correction requirements??
