Re: [Getfem-users] Building a mesh from slice doesn't seem to be possible using getfem-matlab interface

[Julien Pommier]

Hi Arvind,

You can build a mesh from a slice in matlab by exporting the array of vertices
and triangles of the slice ( P=gf_slice_get('pts') and
T=gf_slice_get('splxs',2)) and build the mesh from them with gf_mesh('ptND', P,
T)
