* Severe * DetermineShadowingCombinations: There are 3 surfaces which are casting surfaces and are non-convex

Hello,
We have a hard time trying to simulate HB model to OSM. the error is: 1. * Severe * DetermineShadowingCombinations: There are 3 surfaces which are casting surfaces and are non-convex.

Before that error, we got an error regarding an unclosed surface. After that, we modeled the geometries in Rhino as closed solid extrusions.

Thank you for the help.

This thread was solved privately (i think and hope).
Solar Distribution using the HB_ShadowCalc component was set to 0 and the simulation works now … for me.
