STAR-CD is computational fluid dynamics software developed by Siemens for calculating fluid flow and heat transfer. The ccmg file extension identifies geometry data prepared for use by the STAR-CD solver.
A ccmg file is part of the STAR-CD data workflow and is intended to be read by the application rather than used as a general-purpose geometry exchange file. The software linked with this format runs on Microsoft Windows.
Open a ccmg file with STAR-CD on Microsoft Windows. Use the application's project or solver workflow to load the file; it is not intended to be opened as a standalone document in a text editor or general-purpose geometry viewer.
A ccmg file is solver-ready STAR-CD data, not a general-purpose exchange format, so it normally has no useful standalone conversion. To obtain another geometry format, use the original geometry source or the geometry and preprocessing tools in STAR-CD to export or recreate the data.
