Hi everyone,

Here are three errors from my model using OpenSeesMP, OpenSeesSP with system of Mumps.
For problem 1 and 2, it seems that the Mumps solver is not able to switch to the backup algorithms when the present algorithm encounters singularity matrix.
For problem 3, the model did not run for even 1 step.
Hoping someone could help me out. Thanks in advance.

PS: My model worked for UmfPack, and I only changed the system to Mumps.
