CFD Online Discussion Forums - [mesh manipulation] stitchMesh duplicate point error

Hej,

when using stitchMesh I run into an error about duplicate points. The patches that are supposed to be stitched are two pipes (see picture in attachement). The mesh was created with snappyHexMesh, this might explain the kinks at the ends of the two pipes. The error that occurs while reading the volfields is

Code:

Duplicate point found in cut face. Error in the face cutting algorithm for global face 4(126702 151688 189487 151690) local face 4(303 306 307 308)

Slave size: 28704 Master size: 39064 index: 131.

Face: 5(126702 151688 189487 220642 220682)

Can it be, that because the endfaces of those two pipes are identical, that this error occurs, and if this is the case, how can i avoid this error?
