I'm trying to set boundary conditions on a decomposed case. I'm assuming the ParsedParameterFile should work on decomposed solution files as well. I installed the latest version of PyFoam from the svn repo. I was debugging this case for a long time thinking something was wrong in the way I was setting boundary conditions using PyFoam when I realised that PyFoam couldn't just open and close the file without modifying anything. Could someone tell me what's wrong?

Not quite sure. Could you give me the file in question and I'll have a look

Sorry for the late reply. I figured out what the problem was and a temporary fix around it. My installation of PyFoam could not parse

value nonuniform 0();

This seems to be generated in decomposed cases, whenever a boundary is not located on a particular processor. A work around to this is

sed 's/nonuniform 0()/uniform 0/' processor2/0/nut

or whatever file you want to work with pyFoam later. You may also have to change it to

sed 's/nonuniform 0()/uniform (0 0 0)/' processor2/0/U

for a vectorField.

Bernard, I really want to file a bug report this time. Could you just point me where?

Seems like the parser can't handle fields of length 0. I'll fix that for the next release
