Hi Everyone…

I have been working on a procedural multi-block hexa mesher – primary for cfd use. By ‘procedural’ I mean that you write an input file (*.hgf) containing all needed commands to create the multi-block mesh. From this ‘*.hgf’ file the mesh is created and written in a CGNS formated file (*.cgns). CGNS files can be read by most major cfd programs.

A working windows binary is located in: https://github.com/madsmammen/Hexgrid

Inside HexGrid one can load some demo grid-files to get a feeling of the *.hgf syntax and capabilities.

It is possible to use variables and parameters in the definition of the mesh. Parameters can be changed either in the HexGrid GUI program or in a parameter file (*.prm).

HexGrid can also be executed in a ‘-batch’ mode (without GUI) suitable for automatization with a cfd code. For the moment work is done in integrating HexGrid into ANSYS Workbench.

Any comments is appreciated.
