Thanks John, What would be the straightforward way to append normals and tangents in a single tensor? The idea is to define them as a base so I can operate and iterate. rgds, Renato On Thu, Apr 22, 2021 at 10:21 AM John Peterson wrote: > > > On Wed, Apr 21, 2021 at 10:39 AM Renato Poli wrote:

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
