When I run comsol, it says it has problems below, who can tell me how to deal with that? Thanks.
Time-dependent solver/BDF
Number of degrees of freedom solved for: 4636233
Nonsymmetric matrix found.
Step Time Stepsize Res Jac Sol Order Tfail NLfail
0 0 out 1 2 0 0
Error:
Failed to find consistent initial values.
Out_of_memory_LU_factorization
Last time step is not converged.

I hope that you have a powerfull machine!
"Out_of_memory_LU_factorization" means what it tells you: "out of memory" (RAM)
search for "Out_of_memory_LU_factorization" and you will get a lot of information
