Hello, I am willing to make a coordinate rotation on a Tet face to calculate normal and tangent displacements between discontinuous elements.
As I understand, I need a transformation matrix gathering normal and tangents to define a local coordinate system: T_ij = [ nx_i ns_i nt_i ] I can see all the calculations are there, but I am not sure what is the most elegant/usual way to get such matrix in libmesh. Any suggestion? Any documentation pointer would be helpful! Thanks upfront, Renato _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
