Before revision: A finite element formulation for the computation of cross fields is then presented, which is based on Ginzburg-Landau equations and makes use of edge-based Crouzeix-Raviart interpolation functions.
After revision: A finite element formulation for the computation of cross fields is then presented, which is based on Ginzburg-Landau functional. A discretization scheme with Crouzeix-Raviart interpolation functions.
