BE_CleanUp_STL

choose whether and when to clean up STL geometries

STL files contain the node coordinates for each triangle, so node points that belong to multiple triangles are saved repeatedly. During cleanup, node points are clustered if they are very close to each other and afterwards, degenerate triangles are deleted. If there are other geometry items have been loaded before (e.g. via include{} or as PlainBoundaryElements), then this can lead to problems.

Thus, by default, the STL clean up is only done as long as no other geometry has been loaded. To change the behavior, adapt this parameter.

BE_CleanUp_STL = 0 # never clean up STL geometries BE_CleanUp_STL = 1 # only clean up STL geometries # as long as no other geometries have been included BE_CleanUp_STL = 2 # default: always clean up STL geometries # (may lead to problems in some cases)
