Hi there,   I`m trying to evaluate convergence on my model.   It`s a distillation tower in which I want to perform an hydrostatic test.  It`s a fluid-structure interaction analysis and I finally got my results with no issues.  But when I'm trying to see the convergence chart, it says "no data available".  And when I verify the monitors in the structural solver, everything is set as: Structural - chart #3 with: force convergence - displacement convergence - Solution progression and target. (see image attached).   Is there something I'm not doing well?   I`m also attaching the warnings in case something of this is affecting my solutions.   *** WARNING ***                         CP =      26.938   TIME= 12:56:42 Pivoting has been activated for the Distributed Sparse Matrix Solver . The memory required may greatly exceed the predicted amount.  In that event, use the DSPOPTION command to change the memory mode and/or memory size used by the Distributed Sparse Matrix Solver.

Hello Carlosponte

I'm investigating this issue. I will keep you posted on this soon.
