i have a problem create a mesh for MRF simulation.
The long cylinder is my calculation domain, and the dark one is my MRF domain(the fan was subtract from the MRF domain).
Both domains have the same outer diameter.
I also studied the “drone workshop” but i don’t get the right mesh for my simulation.
so i have some question:
Create multiregion mesh should be set on false?
multiRegion Feature Snap should be set on false?
MaterialPoint should be in the MRF domain?
MRF domain mustn’t have the same outer diameter as the long tube?
