Hello,

i would like to do a rotor/stator calculation. Thus i created two meshes, converted them with fluent3dmeshtoFoam, checked the meshs and renumbered them.
Now i wanted to merge the meshes for the calculation. This fails. Here is the output:

Code:
Build  : 1.6-f802ff2d6c5a
Exec   : mergeMeshes . ../channel3/ . ../Rotor5
Date   : Mar 10 2010
...
PID    : 4782
Case   : /home/bstoeve/OpenFOAM/Rotor/all2
nProcs : 1
SigFpe : Enabling floating point exception trapping (FOAM_SIGFPE).
...
Master: "." "../channel3/"
mash to add:      "." "../Rotor5/"

Create Times
Reading master mesh for time = 0

Reading mesh to add for time = 0

FOAM aborting
What is inetersting about this is: The error occures when the interior faces seem to end. As could be seen from the output of fluent3dmeshtoFoam:

Code:
faceZone from Fluent indices: 0 to: 21733697 type: interior
patch 0 from Fluent indices: 21733698 to: 21881973 type: wall
patch 1 from Fluent indices: 21881974 to: 21889726 type: wall
patch 2 from Fluent indices: 21889727 to: 21947236 type: wall
patch 3 from Fluent indices: 21947237 to: 21969365 type: wall
patch 4 from Fluent indices: 21969366 to: 21988347 type: wall
patch 5 from Fluent indices: 21988348 to: 22007989 type: wall
patch 6 from Fluent indices: 22007990 to: 22028676 type: wall
patch 7 from Fluent indices: 22028677 to: 22049363 type: wall
Has anybody experienced something like this before?

Hi,

well, i 'solved' the problem by not using fluent3DMeshToFoam. It doesn't work (at least in version 1.6). Using fluentMeshToFoam works.
