While using stl file for geometry, I wonder if there is the way to define stl facets as a non-slip wall region.
I couldn’t find the instructions in documentation.
Thank you.
EBs, defined by amrex native functions, 'csg' 's or 'stl' 's are by default treated as NSWs. Although I will warn you that the 'stl' method should still be considered developmental. However, if you are just doing the simple rectangular riser of your other post, I don’t think you need complex geometry at all. You should be fine just using a native box and defining a flow on EB region.

Does it works the same in PIC?
It works the same for the fluid whether you are using DEM, PIC, or no solids at all.
