Hi,
I am not sure if this addresses your question, but is there a particular reason you want to use symmetryPlane only? If I remember correctly from the documentation for symmetryPlane, it states a rather stringent requirement in its definition and suggests the "symmetry" BC as a less strict alternative. Have you given symmetry a shot for your problem? Cheers, Antimony |

may be you could try using the preservePatches( ) within the decomposeParDict. I did not test it though!
