Persalys 19.1 - bug while testing a FMU

Persalys usage
1

Hello,

I imported a FMU file into Persalys 19.1 (appimage, on Ubuntu 24 LTS), and I got the following error.

I have checked the documentation : Installation — Persalys 19.1 documentation

assimulo.exception.AssimuloException: No support for SuperLU was detected, please verify that SuperLU and SUNDIALS has been installed correctly.

My FMU was build in Model Echange mode, and depends on the solver provided by Persalys.

However, no problem with FMU exported in “Co-simulation” mode, with embedded solver inside the FMU itself.

Is there any special requirements for Persalys to run FMU in “Model Exchange” mode ?

hi, we enabled the superlu solver for the next version

turns out pyfmi switches to a sparse solver when >=100 variables
