patchMap

Carlen · September 21, 2015, 21:53

Hi foamers,

I am wondering if I can use mapFields utility to map the vectorFields from one patch to another without mapping the internalFields? Mapping the internalField takes too long. I have searched throughout the forum that patchToPatchInterpolation should work, but it does not seem to work in parallel. Any suggestions?

Thank you very much!

yes you can map patches to each other.

requirement is, that they have the same location as described here:
http://cfd.direct/openfoam/user-guide/mapfields/

you can define patchmap in mapFieldsDict.

I had some problems with the mapFields-utility in Version 2.3.x and 2.4.x -- since there is parallel support implemented, patchmapping did not work for me -- serial and parallel.
So i switched to 2.2.x for the mapping process.

Thank you very much for your help Pfender.

I have no problem using mapFields and have successfully integrated it into my code mapping data every timestep from one mesh to another. The problem is that it takes too long and I intend to do an implicit coupling using patchMap which is faster than mapping volume fields. I have looked into the partchToPatchInterpolation, but it does not work in parallel. Any suggestions?

I appreciate your time.

This is also of interest to me, I want to map data from coarse patches to finer patches in my solver. It may be possible to use it in parallel if the case is decomposed in such a way that each patch is on one processor only.

Hi chriss,
Unfortunately OF does not have such capability as far as I know

See here for a possible method.
