Compressed file of the local model mesh

The local mesh is available in the file _LocalMeshModel.vtk using the ascii vtk format (see https://vtk.org/wp-content/uploads/2015/04/file-formats.pdf). The mesh is a finite elemen tetrahedron based grid and it is reported following the UNSTRUCTURED_GRID format:* Points coordinates, one point per line; * Cell Types (cell type is 10 for tetrahedrons according to the documentation)* Cell number and size (that is to say the total number of vertices) followed by the list of the ids of the points for each vertex on a cell by cell basis.
