[BlockGeometryStatistics3D] No discreteNormal is found

[jrfriggo]

Hey guys, good afternoon!

I’ve tried to change the geometry of one of the examples simulations, exchanging the cylinder3d.stl file for another cylinder3d.stl file with a different geometry, I thought that would made the program run the simulation normally in another geomtry, but it just didn’t work, displaying the error “No discreteNormal is found”. Does someone know how could I change the geometry in the simulation and still get any result?

Thanks!

Dear jrfriggo,

You may consider taking part in our next spring school, where we explain how to set up a geometry step by step. It is hard to see what your problem here is.. Basically, in OpenLB you set up a geometry by indicator functions which can be given by stl files or geoetry primitives like cylinders, cubes, spheres, etc.

Best
Mathias
