Apologies if this has already been asked but I couldn’t find it anywhere of the internet. I’m trying to find the mass flow rate through a cylinder in dsmcFoam. I used the blockMesh then snappyHexMesh for the geometry, so the inlet of the blockMesh patch is not the same as the cylinders open end.
Is it possible to make a surface at the inlet and outlet using the slice or clip feature? Then later make this a patch so I can integrate the velocity over it.
Below I’ve attached a screenshot of what I’m working with.
Any advice would be greatly appreaciated!
