Bad points error when I try to have a couple of ACMI interfaces created via createBaffles utility. Bad points (coincident) fatal error while computing normal, but checkMesh is ok. Link to error report in cfd-online forum. More details and pictures there. https://www.cfd-online.com/Forums/openfoam-pre-processing/199051-issue-creating-acmi.html |

I'm sorry to say that your report does not follow the rules for this issue tracker: https://bugs.openfoam.org/rules.php Namely: - A clear description of the problem to help others who encounter a similar issue in the future. - Evidence that user error is not the cause of the issue. Having all of the actual information placed elsewhere makes this issue pretty much useless if the two links are ever deleted. Either way, running "checkMesh -allTopology -allGeometry" reveals that this mesh has a lot of problems, not just a "high non-orthogonality warnings at the most". Attached is the log file that shows the output of the aforementioned command. Partially quoting (what should have been written on this report originally) from the forum post that you've mentioned, for future record: ---- I am encountering an annoying issue while creating ACMI interfaces. Particularly, when the createBaffle utility calculates the faceAreaWeight, I get a bad points error. --> FOAM FATAL ERROR: Bad points:(0.0488523 -0.0409136 0.0101859) (0.0488523 -0.0409136 0.0101859) (0.0488523 -0.0409136 0.0101859) From function void Foam::plane::calcPntAndVec(const point&, const point&, const point&) in file meshes/primitiveShapes/plane/plane.C at line 90. FOAM aborting What I got is that the calcPntAndVec function (plane.C at 90) is trying to evaluate the normal of the triangle made of three points that are actually coincident. So the utility complains and I cannot have my ACMI built. In the attachment, the boundary mesh and the bad-overlapping points depicted in red. The mesh is ok (high non-orthogonality warnings at the most). Any ideas on how to fix this? Many thanks in advance. ---- |
