I’m starting to simulate the flow on in a river bend. Now I’m defining the material in the inflow and outflow sections. I have some irregular geometries that define the cross section. How can I implemented it? I’m stuck by a while trying to solve this issue.
In OpenLB you can take an intersection (with operator *) of the stl-file and any othe geometry indicator (like a cube). At least you will get a voxel presentation of what you want.
