4.8 GUI-Tools

4.8.1 pyFoamDisplayBlockMesh.py

Graphically displays a blockMesh and helps highlights selected blocks and patches. It is not a blockMesh-editor, but it helps to find errors in the order of vertices etc (editing of the blockMesh is still done in a text editor).
This needs an installation of the VTK with Python-bindings. The ways to get this are very different on various systems. But usually you have to compile it from the sources. Sorry.
