Question GUI based pre processor development for OpenFOAM

Hi everyone,

I am an amateur CFD enthusiast and I am trying to create a GUI for OpenFOAM, for pre processing as of now, like loading a case, viewing the mesh and boundaries separatey, maybe even meshing using snappyHexMesh. I am thinking about using PyQt and MayaVi which is based on traits and VTK for this purpose. Would you recommend any other packages, as I have limited time to get it done. Also how do you manipulate a mesh file in mayavi as in, say ParaView or EnGrid, by selectively choosing and displaying boundaries and cross section planes. Should I convert the .foam to VTK format for viewing and manipulating it? And is there anyway to embed a mayavi pipeline browser in the Qt application window because that will ease things up a lot especially for manipulation I guess.

Thanks a lot for the help in advance, though i know it's a bit long :\

We have built our commercial CFD pre- post- processor (Ennova) based on VTK and QT. Here is our website ( . Several tutorial videos are available at and . So this will give you an idea of how it turned out.
