Mapping Boundary Conditions to Another Case

I am setting up a case to simulate flow in an rectangular cross-section, s-shaped duct using OF1.6 . The flow is turbulent(Re 40 000), and I am trying to reduce computational time in two ways. First, I would like to run the case in parallel and second I would like to reduce the inlet length(and mesh size) and be certain that I have fully developed flow as my inlet boundary condition. To accomplish this I have considered using the directMappedPatch technique, and I have created a case for a simple straight duct. As far as I can tell, this technique does not work correctly in parrallel cases though(reconstructPar fails.) I have tried to use the manual decomposePar method to enusre that the directMapped patch's exist in all processor cases. I used the hierarcichal method and selected 1 processor in the mapped direction, reconstructPar still tells me it can't find the region0.
Code:
Did not find sample (0.15 0.00152006 -0.0393227) on any processor of regionregion0 From function directMappedPatchBase::findSamples(const pointField&, labelList&, labelList&, pointField&) in file directMapped/directMappedPolyPatch/directMappedPatchBase.C at line 337. FOAM exiting I have a feeling that this should be possible, but there is something I am not quite getting. Hopefully someone can provide me with some advice.
