Hello, I am trying to solve a system of poroelasticity using P2 elements and sparsesolver. Number of mesh elements - 43936, number of mesh nodes- 21974.
The output I am getting is :
Error umpfack umfpack_di_numeric status -1
Error umfpack_di_solve status -3
I would like to ask what does this message implies.
hi,
Did you find any solution to that problem ?i have the same error and only with p2 element type?
I have also had the same error, with P1 elements, and only on finer meshes. Any understanding of the issue would be great!
If you set the verbosity higher or try another solver do the messages help
point to a specific issue?
Thanks for your reply. I solved this issue with UMFPACK64
