It maps fields from a case to another. The syntax is:
mapFields <source root> <source case> <target root> <target case> [-consistent] [-parallelSource] [-parallelTarget]
The available options are the following:
- -consistent: it maps a field consistently. The source and the destination have the same geometry. If this option is not specified, it is necessary to define a dictionary named mapFieldsDict in the system directory of the case.
- -parallelSource: it specifies the source case is decomposed for parallel calculation.
- -parallelTarget: it specified the destination case is decomposed for parallel calculation.
The syntax of the mapFieldsDict is the following:
patchMap ( <coincident patches in the two cases> ); cuttingPatches ( <target patches who has to be mapped from the original internal field now cut by patches> );
An example of use can be found in the official OpenFOAM user's guide (see page U-31: mapFields ../cavity -consistent)
