Hello!


i am using OFv2012 on ubuntu and I have a multiregion case.

You can basically see my problem in the attached file... why does the solver also save the ddt()... files? Is there something wrong or is that normal for OF.com? (i have only worked with OF.org version8 before)


Also, when i run the solver, loops over every region multiple times. For example:

time 1:
- region 1
-region 2
- region 3
- region 1
-region 2
....
That is not normal, is it?



My workflow:
1. cfMesh every single region (sHM does not make me happy in this case)
2. topoSet cell and faceZones for each region
3. mergeMeshes
4. createPatch for the this_to_that patches
5. splitMeshRegions -cellZones



the solver crashes for steadyState at time 0 but runs (with the strange behaviour) for Euler and CrankNicholson 0.9.


Does anyone have an idea what is going wrong here?
