Solution to Mumps Error

Hi,

I have a large model and I'm using OpenSees on an HPC platform.
My analysis script consists of two phases: static and transient analyses.
Since my model is large I cannot use any system solver other than Mumps or the analysis would crash.
If I use Mumps in both phases, the transient analysis doesn't work.
What're the possible solutions to this?

Cheers,
Arman

do the static analysis with a transient analysis .. sorry but there is some bug in Mumps related to memory when we destroy one instance and start the next.

Which version of the Opensees source code are you using? A bug fix for that was included in release r6608. But if you have the source code updated, if seems that the problems corresponds to another thing. If interested, i can provide you with the source code i used (for the windows platform) to solve the issue, and try to work out a solution for the problem starting from it.
