I have a Windows 7 , 32-bit system with 4 GB RAM and I am simulating the rotational benchmark model using COMSOL 4.3a with Update 2. The degrees of freedom of my system is a little more than 70,000. I am using the direct solver PARDISO. I read that the number of DOF is the reason for the system running out of memory as there is a higher limit to the DOF in a 32 bit system. I also tried the Iterative GMRES solver, it shows an error:
The system might have reached a singularity. What should I do to run the model effectively on a 32 bit system?
