Hi,

I am getting an error while I run a model in Openseessp with the triangle elements-tri31 (the same model works fine with quad elements), and I am wondering is there anyone else who faced the same problem? Does Mumps support tri31 elements?

This is the error:

""""

"""""

Bests

it is either Mumps or the triangle element not sending themselves correctly .. does the error occur on the first analysis step?

Yes. The analysis does not start at all. I found this could be the source but I do not know how to fix it.

Some elements are not created for parallel compiting. In my case, I use section LayeredShell which doesn't work in parallel.
