    Hi everybody,

    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.

    The geometry is here: https://ibb.co/bx0hV7

    After, I have to change the boundary condition at the top of the geometry. So I think it is the solution is in a similar way.

    Hi again everybody,

    I’m still working in this issue. I’m wondering if is it possible to read the cross sections from a stl file?

    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.
