[Gmsh] Negative Jacobians in 2nd Order Mesh

2020-09-04 Thread Nikhil Vaidya
Hello, I have a geometry for which 1st order tetrahedral meshing works fine (with no negative jacobians). For the 2nd order case, I get a few negative jacobians. This problem does not go away even when I try to regularize the mesh or reduce mesh sizes in certain regions with small geometric
