Memory Problem COMSOL

[robertsmith02]

I am studying sonar detector of large under water systems. I m using a simple test case in COMSOL at the moment but the memory size of my problem is too big for my PC. I tried to reduce the mesh but I had convergence problems can you please help me indicating which mesh settings I should choose?
Thanks

Try using a coarse setting with a mapped mesh. Although, you may want more RAM

When I was at the university, i was using OOFELIE to simulate a submarine and never had this kind of problem with the memory. I never used COMSOL though, so I can’t really help you with this.

I uspect a more fundamental problem. In Optimesh, at least, half a million dofs will run in 1.5 GB of RAM.
