[vtkusers] vtk old legacy polyhedron

[David Uystepruyst]

Hello Herve, 

Thank you for your answer. 
I already saw this page. It looks like functions to perform binary files. 
I'll go further to find the equivalent in ascii format.

Hello David, 

This explains the format for polyhedral blocks. Make sure you use the faces and facestream tags.

Hello, 

I would like to create an ASCII output files in vtk (unstructured) format from a CFD code written in fortran. 

The main parts of cells are cartesian hexa (cube) but the boundary cells can be polyhedral (convex and concave). 

Then, I want to use polyhedron cell type (referred as 42 in vtk) but it seems difficult to find examples ? 

I guess polyhedron cells need more informations as there is no specific order for the nodes ? 

Thanks,
