cfspart is used to re-partition multi-zone common flow (.cfl) and boundary data (.tda) files for an unstructured grid into a different number of zones. The primary purpose is to allow restarting an unstructured grid case using a different number of processors, while still having one zone per processor.

cfspart requires as input two multi-zone common grid (.cgd) files, both created from the same single-zone unstructured grid using the cfpart utility. One of the .cgd files corresponds to the "old" grid used for the existing .cfl and .tda files, and the other corresponds to the "new" grid, with a different number of zones.

The user is prompted for the names of the old and new files.
