Hello I have a model of contact, when the grid have done very fine , it cannot solve. it posts an error Exception: com.femlab.jni.FlNativeException: Out of memory during assembly Messages: Out of...

I belive this problem is very similar to one which I have encountered during solving very fine meshed problems(comsol sayed : out of memory during LU factorization) . The operation's demand for memory...

Hi Hoa, I also had some experiences with the problem. Let try with the following things: - Make mesh less fine with sub-domains not important or all of sub-domains - Using symmetrical geometry...

On Page 124 of v3.5a User's Guide there is a description of how to increase the default Java heap space by changing the MAXHEAP variable in the file comsol.opts, which is loaded on launch. The default...

Another approach might be to experiment with using different linear solvers. Some of them require a contiguous heap, some don't, and at least one of them allegedly does the calculation out of core....

Hi - since I am running into the sampe problem of too little memory I am looking for answers and found your comment. I dont't think that increasing Java's heap space does solve the problem because the...

Hi, MAXHEAP will not solve the problem. This is not a magic parameter. MAXHEAP is also limited by the available memory and has nothing to do with the solver. There is a limit in your memory which is...

I have received similar error with very few and coarse mesh on a very simple geometry. I have 3GB available memory and >2Ghz dual core CPU! Isn't it odd? I have used to run other commercial programs...

I would suggest first to use less mesh if possible. If not possible to use less mesh, then get a 64-bit computer with more memory. You can also try the segregated solver and iterative solver to reduce...

Since posting my comment above I bought a new quad-core machine with 24 GB memory, and am running Win7-64bit. The old our-of-memory problems disappeared, but it's easy to make them reappear again with...

About a slightly different set of limitations - I wanted to know where a simulation was spending most its time, so I exported to an M-file and ran it from Matlab with the profiler turned on. It turns...
