Hello everyone,
I'm writing a piece of software (in FORTRAN) to perform CFD calculations, based on a particle method. To generate the initial particle distribution over complicated domains, I'd like to use the mesh information (node coordinates) generated by STAR-CCM+ and simply put a particle in each FV node.

So my software must read from an existing mesh file.

Does anyone know any source of information no how a mesh file is written in STAR-CCM+?

I'm looking on information on such questions as:
-> How the nodes are numbered, where they are located on the file, etc.
-> Does it start writing the nodes from bottom to top, left to rigth, etc.
-> How are the nodes on solid walls written, where they are on the file, etc.

I'm acquainted with Star-ccm+, so I would like to use this program to generate the mesh if possible. However, I'm not finding any information on the specific way the mesh information is written in a .ccm file.

Thank you for your time,
André Almeida

The best place to look for documentation of any kind are the help files and the steve portal.

That being said, there is no 'mesh file' for star ccm+. You have one file that contains mesh, results, geometry... everything. However, you can export many file types and specify mesh, results, or both. I would recommend Tecplot as this is pretty straight forward in terms of connectivity and syntax although will require Tecplot to view and interpret.

Thanks,
I'll check the portal
