| Summary | 0004152: Fix for mapped patches in case of a single face in a parallel case | ||||
| Description | If a mapped boundary is decomposed in such a way that some processor has only one neighbour face and the default tree mapping method is used, the creation of the bounding box fails. This is quite rare, but can occur in realistic cases when large number of cores is used. I have attached a trivial example case and a minimal patch to handle such a case. | ||||
| Steps To Reproduce | Run ./Allrun, the parallel version fails | ||||
| Tags | No tags attached. | ||||
