+ | ==== Making a mesh with Moulins ==== | ||
+ | Moulins are 101 boundary elements. ElmerGrid does not export correctly 101 boundary elements from gmsh or when partitioning a mesh. To add 101 boundary elements to an existing mesh, thanks to Mondher Chekki (IGE), one can use the python tool '' | ||
