Error occurs in UMFPACK solver 3D problem

Hello everyone!!!
While handling the denser meshing style in the 3D domain, the solver “UMFPACK” is failing.

error is

error umpfack umfpack_di_numeric" status -1 error umfpack_di_solve status -3

Also, suggest suitable a SOLVER that can handle complex mesh in 3D problems.


Please help me to fix this error. Also, comment on how to

Use MUMPS, that’s much more efficient and works in parallel.

Thanks @prj

For now, I am not using MPI and parallelization for the code.

Also, directly using “MUMPS” shows an error.

Can you please suggest any alternate way to handle this issue?
