I am working with XFEM for crack propagation. When I postprocess my results with Tecplot, I would like to actually see where the crack passes and split the elements crossed by the crack. This means thad 4 nodes FEQUADRILATERAL can end up with 5 nodes. IN CGNS it is possible to write these type of elements using "NGON_n" connectivity. Is there any way of doing this with TecIO library directly? It is quite a pain to work with FEPOLYGONS and I would like to avoid this.
