Hi, I have written some FEM code in Matlab that handles 27-noded 3D unstructured meshed. It reads all the mesh info, including connectivity matrix, vertex coordinates , etc. from Cubit/Trelis output in ExodusII format and gives me a mesh object in Matlab. So after FEM processing and getting my solution, I would like to use Paraview as a postprocessor. So I wrote a piece of Matlab code so I can write the connectivity matrix, coordinates, and unknowns “u” (in this case displacement in 3D [solving hyperelasticity]) to a vtk file. The only thing I am not sure what I should use for the 3D 27-noded is the CELL_TYPE when I am writing to the vtk file. Is it 12, 25, or something else? 12 seems to work as Paraview shows me that it has correct number of nodes from the mesh, but when I ask Paraview to show the nodes, it only shows the vertices as apposed to nodes on vertices edges, faces and cells. When I use 25, the mesh does not look correct. It gets distorted and collapsed. The connectivity looks totally incorrect. These numbers are based on https://www.vtk.org/doc/nightl y/html/vtkCellType_8h_source.html
I would appreciate any help. Thanks Arash
