Error message in OpenSeesMP

[hadisayadpour]

When I run my model in OpenseesMP it prints the following error:
parallelMumpeSolver:: Error -9 returned in substitution dmumps

what is the cause of this error?

[fmk]

probably the model .. did you run 1 step sequentaiily to see if that worked.

[hadisayadpour]

Frank,
I run it sequentially and it worked well.
I have some MPConstraints (equalDOF) in my model. when I deactive this constraints every thing is well but when I activate those, the error will appear.
I used Penalty method to impose constraints and there is no problem with the sequential OpenSees but in the parallel version (OpenSeesMP) the error will appear when I use factors greater than 1e10 for penalty method.
Do you have any idea about this problem?

[fmk]

for each MP constraint added in a processor, the 2 nodes must only exist on that processor.

[hadisayadpour]

So what should I do if for example I have nodes 100 and 101 in two processors and I want to tie them together?
I should tie them in just one of these two processors and they will tie together in both two processors?!

[fmk]

the 2 nodes have to exist in the processor containing the MP constraint .. you might try adding the nodes and constraint to both .. i don't believe the nodes have to be attached to any ele . but it has been awhile since i wrote the source code.
