Neks, I am trying to import some mesh information into prenek via a vtk file. Can someone please post an example of one that works into the git repo? Ideally it would be nice to have a 2d and 3d case for vtk files that work in prenek. I have tried using the vtkUnstructuredGridWriter class from the vtk library and prenek does not accept the file. At first I thought it was because the class required 3d points and I am importing a 2d mesh, but after I modified the file to remove the extra coordinate and make it match the style guide ( http://www.vtk.org/wp-content/uploads/2015/04/file-formats.pdf) prenek reads the mesh without crashing, but no elements appear. The output to the terminal from prenek is: IMPORT VTK MESH Current number of elements: 0 input name of vtk file 4 0 1 2 3 inside gencen 0 F 4 done gencen 0 The contents of the file I am trying to import are below, so if you see a bug please let me know. # vtk DataFile Version 4.0 vtk output ASCII DATASET UNSTRUCTURED_GRID POINTS 7 float 0 0 2.1 0 1.48492 1.48492 0 2.1 3 0 2.12132 2.12132 0 3 CELLS 3 15 4 0 1 2 3 4 1 4 5 2 4 3 2 5 6 CELL_TYPES 3 9 9 9 Thanks, -- Phil S.
