Hi,
The attached poly.dat is the correct one, I manage to run the case with mfix-23.1.1 in batch mode (I am not using the GUI version because it does not support poly.dat and I want to run a 2D simulation). I use 23.1.1 because I could not find the source code of the latest version (see https://mfix.netl.doe.gov/forum/t/where-to-find-the-source-code/5283.
I have an update. Activating the gas phase I managed to complete the simulation. So the issue seems to occur when disabling the gas phase.
Thanks
Fabio
