Trouble migrating oodles to pisoFoam while changing from OF 1.5 to 1.7
 
Hello together,

I want to move from OpenFoam 1.5 to OpenFoam 1.7. The installation of the 1.7 version works quite well and the tutorials perform as they should do.

After testing this I want to use a case I solved with oodles in OpenFoam 1.5 in OpenFoam 1.7. I've read in this forum that pisoFoam replaces oodles, so I tried this and after copying the turbulenceModel file from the pisoFoam/les tutorial pitzDaily it startet working.

But piso's pressure correction seems to make some trouble. Neither PCG nor GAMG can achieve any kind of convergence. In both cases they use all Iterations I gave them by maxIter and blow the residuum from 0.8 to 10^33.

Has anybody had a similar problem or does anybody see my mistake in migratin from oodles to pisoFoam ?

Thanks a lot,

Sebastian
