Hello!
Visualising my results, the channel edge has jagged/fuzzy edges not present in the mesh. However, the points of these fuzzy edges do match those shown in the "ipobo" file.
Could there be a problem with how Telemac is reading this mesh? i.e. perhaps the boundary nodes are being read incorrect?
I've not had a problem with it before, so it's puzzling. I remade the boundary file, and visualised the mesh using different post-processors (BlueKenue and Paraview).
