I have many results of “vtk” file from the other fluid software, and I need to input these “vtk” files into my FreeFEM++ programs to calculate next step. The mesh of “vtk” is two dimensional, and the cell type is 9. I used the “vtkload” to read the “vtk" files, but I failed. It seems like the FreeFEM++ has not include the type “9” of the cell of the “vtk”. Is anyone has good solution for this?
The type 9 of cell of “vtk”
