Summary0001121: impossible to create cyclic BC between patches of two different regions of chtMultiRegionFoam
DescriptionWhen the cyclic patches connect two different regions, chtMultiRegionFoam solve produces this error message:

=====================================================================
keyword startFace is undefined in dictionary "::cyclic_top"

file: ::cyclic_top from line 61 to line 61.

From function dictionary::lookupEntry(const word&, bool, bool) const
in file db/dictionary/dictionary.C at line 400.
=====================================================================

It doesn't seem to create pass the information about the BC into cellToRegion and boundary definition files within 0 directory.


The problem is also described here:
http://www.cfd-online.com/Forums/openfoam-pre-processing/115234-chtmultiregionfoam-cyclic-bc.html

Steps To Reproducecreate a box-like domain of two parallel regions
assign cyclic boundaries to opposite sides of the box so they have no common region
Additional InformationThe feature makes sense when connecting/simplifying fluid domains/regions but not when doing the same to solids where heat is what should get passed.
TagsNo tags attached.

It is not possible to have cyclics inbetween different regions. Use e.g. a mappedField boundary condition.
