Hello,


I am trying to use the mapFields function on foam-extend 4.0 to map the results of a CFD simulation onto the fluid domain of an FSI simulation.

I have seen some people use the -targetRegion option for mapFields but when I try use that I get the error:
Code:
mapFields -sourceTime 'latestTime' -mapRegion fluid ../finalCfdSim/

Usage: mapFields <source dir> [-DebugSwitches key1=val1,key2=val2,...] [-DimensionedConstants key1=val1,key2=val2,...] [-InfoSwitches key1=val1,key2=val2,...] [-OptimisationSwitches key1=val1,key2=val2,...] [-Tolerances key1=val1,key2=val2,...] [-case dir] [-consistent] [-dumpControlSwitches] [-noFunctionObjects] [-parallelSource] [-parallelTarget] [-sourceTime scalar]  [-help] [-doc] [-srcDoc]



--> FOAM FATAL ERROR:
Wrong number of arguments, expected 1 found 2
Invalid option: -mapRegion
Can anyone help me with mapping one source region to a case with multiple regions please.


Thanks

I finally found my answer,


I was using foam extend 4.0 which does not have this functionallity. So I just downloaded a main branch version of openfoam which has this option for mapFields, and initialised that new version of openfoam, used mapFields, then initialised back to foam extend 4.0.
