Impossible to mesh periodic surface - OCCTargetUnit
Hi, I am generating 2D surface meshes for some 3D geometries. I was taking "Impossible to mesh periodic surface" error for some of the geometries. After I used different OCCTargetUnit, I noticed that gmsh could actually generate meshes when suitable OCCTargetUnit is used. For some geometries I get successful results with OCCTargetInit=MM, for some with OCCTargetInit=M and for some with OCCTargetInit=KM. My geometries are in a .step file. When I check step files, all geometries include the following lines: LENGTH_UNIT() NAMED_UNIT(*) SI_UNIT(.MILLI.,.METRE.) As far as I understand, all of them has the unit MM, but for mesh generation operation they need different OCCtargetUnits. How can I understand which OCCTargetUnit is the suitable for that geometry?
Tahnks.
