Hello Foamers,

Basically my problem is that I want to decompose a case, run it out for a certain number of iterations, refine where needed using a cellSet by field and then refineMesh (both with -parallel), map the coarse mesh's fields onto the finer mesh and then continue, I was hoping to do all of this without reconstructing the mesh. (By the way I'm working in OF 1.7.1.)

My only sticking point so far is the fact that when I run mapFields with the -parallelSource and -parallelTarget flags the command throws some warnings (see output below) and nothing is written out in the target directory. It looks to me like each of the source processor directories tries to map to each of the target processor directories, which doesn't make sense.

I make the call like this from the target case directory...

mapFields ../test1 -parallelTarget -consistent -sourceTime latestTime -parallelSource

The geometry is consistent between the two meshes, the only difference is the refined mesh in the target case. I've checked in paraview and the refinement worked correctly. I've also tried running this without the -consistent flag and with a dict file explicitly mapping each boundary to itself and it still doesn't work.

Does anyone have any experience working with mapFields in parallel? I have no clue what I'm doing wrong!

Thanks.
