So maybe it's due to some instability (like unconstrained DOFs), and in those cases, some solvers might be more tolerant than others.
Thank you for your explanation.

it will disappear on the next OpenSees version
Will this be updated in OpenSees-solver?
If not, do I need to download the ...

When you use more than 1 partitions, the only solver/numberer combination that can "UNDERSTAND" that each process is one part of a bigger model (domain decomposition) is MUMPS+ParallelRCM. All others will think that each process has its own stand-alone structure

I think my wording might have ...

UPDATE INFO：
Additionally, I created a model with partition 1, but the results still cannot be displayed.
This really confuses me.

One more question is that I want to use UMFPACK+RCM (with OpenSees) on this model, but it fails to converge in the first analysis step, while MUMPS+Parallel RCM (with ...

Hi STKO Team：
To simplify the model, I only created a three-dimensional structure of the soil.
But I encountered the same problem.
MODEL INFO:
·Soil dimensions: 48m * 21m * 30m
·Partitions: 16
·Perform elastoplastic gravity analysis on the model
Here are the problems I encountered.
I've also ...

Dear STKO Team:
My model utilizes the ASDConcrete3D material, I upgraded my OpenSees-Solver veision from 3.4.0 to 3.7.2 (both are compiled versions by Prof. Tarque).
However, after completing the calculation using version 3.7.2, when I try to open the post-processing file, I receive a prompt ...
