Hi experts,
I have a problem with pyFoamPotentialRunner.py.
I use it in pitzDaily tutorials but after it sets case for potential solver it crashes!
here is the error:

Setting system-directory for potentialFoam
Traceback (most recent call last):
  File "/usr/local/bin/pyFoamPotentialRunner.py", line 5, in <module>

Any suggestion?
