Hello guys,

i want to simulate a symmetrical model in OpenFOAM 1.6. I used to work with *.stl-Files (ascii) out of CatiaV5. If im working with the full model the simulation is running correctly.
My Problem with the half-model:
- Look at this link
http://img541.imageshack.us/img541/3825/halbmodell.png
- The half-symmetrical-model is pushed together...
- How can i use the model correctly?
- I dont want that the displacement is moving together
- The log-file writes:
Calculating patchDisplacement as distance to nearest surface point ...
Wanted displacement : average:0.0648462 min:1.19234e-07 max:0.345365
