Good Morning dear Community,
I have an issue with the mesh in my Level set problem, Elmer gives an error message in the output file, it stops in the first iteration. I attached the output, the case.sif and the mesh in a link: https://we.tl/t-mzCiiYozwU. Thanks in advance for your answers.
Regards,
Andrea

Re: LEVEL SET: PROBLEM WITH MESH
I get that error when using
Linear System Solver = direct
Linear System Direct Method = umfpack
because I run out of system memory.
I have had success using
Linear System Solver = direct
Linear System Direct Method = Mumps
in its place.
Linear System Solver = direct
Linear System Direct Method = umfpack
because I run out of system memory.

Thanks for your constant help. How can I install MUMPS?

Re: LEVEL SET: PROBLEM WITH MESH
It is part of Elmer on a unix system, I don't think it has been done on Windows. You can search mumps windows on this forum.
You can switch to the iterative solver instead of direct.
Linear System Solver = Iterative
Linear System Iterative Method = BiCGStab
Linear System Max Iterations = 500
Linear System Convergence Tolerance = 1.0e-8
BiCGstabl polynomial degree = 2
Linear System Preconditioning = ILU0

I have Ubuntu and fedora machines too. So, for example, how can I install it?

Can you post the sif for that one?

Re: LEVEL SET: PROBLEM WITH MESH
I think
Linear System Solver = Iterative ! direct
Linear System Direct Method = BiCGstab ! umfpack
should be
Linear System Solver = Iterative ! direct
! Linear System Direct Method = BiCGstab ! umfpack
Linear System Iterative Method = BiCGstab
Linear System Solver = Iterative ! direct
Linear System Direct Method = BiCGstab ! umfpack
should be
Linear System Solver = Iterative ! direct
! Linear System Direct Method = BiCGstab ! umfpack
Linear System Iterative Method = BiCGstab

I have changed as you said, but it gave me the same error message.
