I installed Ubuntu 18.04LTS and built mpi90 for DMP. After 8 hours (walltime) and 0.135s simulation time, solver gives this error and stopped. My MFiX version is 20.4.0. I tried to search this error on google but didn`t find anything.

What model are you running?
PIC; similar to that problem which I linked below (But I solved the negative density problem with mesh refinement)
I need to help for my case. I want to model an industrial-scale CFB boiler with internal baffles. I tried to solve it at different times and different meshing and modeling approaches.
This is my geometry. My boiler has a one rectangular baffle + some u beams.

When I tried to run with just a rectangular baffle, my problem can be solved. But I try to mesh for u beams, my simulation can’t be converged. So, I create a lot of internal (impermeable) surfaces that act as u-b…
