Hi all, I'm trying to convert an adaptive tetrahedral mesh generated by Sentaurus from their grd format to Gmsh's msh format for importing in my program which uses LibMesh. I keep getting the following error due to improperly ordered nodes in the element:
ERROR: negative Jacobian -2.85931e-06 at point (x,y,z)=( 1.54167, 1, 0.5059) in element 69 When I manually reorder the nodes for the above element, the error is fixed for that element. Is there a simple way to correct the node ordering so that I can use it in my conversion code? I tried computing the volume using triple vector product, but I still get this error for some elements. I'm using first order Lagrange basis functions. Thanks!
