At what point does it fail (right at the beginning, when the silo is empty…)? I let it run for a few minutes and I didn’t get any error.

Thank you for your reply! It’s right at the beginning when i load a solved case with some particles in the silo. Once i run the mfix, the problem appear, and i can’t start a new project.

I just try to load again ,it’s ok to run ,maybe it’s a sudden error or conflict with paraview. Thanks again.
