Problem with stitchMesh: it does not work in meshes with several common patches
I am using mergeMeshes and stitchMesh to merge several meshes and to get rid of internal faces, as they are not supported by OpenFOAM. Everything works fine since the patches I am stitching are perfectly conformal and the geometries very simple. However, when I try to stitch more than one pair of patches in the same merged mesh I get the following error (please see the explanatory chart I have attached):
Thank you very much for your time.

unfortunately I can't help you yet. Just for your information, the same thing has lately been observed and discussed in other threads:
Maybe you could provide your test case or a minimal working example too.
Thank you very much, Cutter!
I found a way to work around this problem a couple of days ago (it works at least in OpenFOAM 2.1). I post it in case anybody else experiences the same problem:
Do not ask my why, but for some reason, you have to run stitchMesh with the "-perfect" option. E.g.:
By the way, the files *Zones and meshModyfiers in ./constant/polyMesh can be the source of other errors, so do not forget to delete them after every stitchMesh. Besides I have observed that in some OpenFOAM versions all patches, both internal and boundary conditions, have to be defined in ./0 when you stitch meshes.
