Geometry change on rotating drum tutorial

Hello everyone,

I’m beginer with M-FiX and tried the rotating drum tutorial. after that I wanted to change the geometry so that I could control the dimùensions of the drum. I simply used the cylinder primitive and began with the exact same dimensions as the original stl file.
The simulation runs with no errors but doesn’t generate any particles while I didn’t change anything about the Initial Particles region or the initial conditions. Do you know the cause of the problem ?

Thank you in advance,
Antonin

problem


primitive

Fixed, I finally found how to flip the normals of the primitive.
It’s funny how the idea emerges only after you ask to the others

Excellent! Yes it is always a good idea to verify the normal orientation.
