Hi,

Based on the log, there is no error message, just a warning. The warning simply tells you that OF put boundary faces it couldn't associate a name with into a patch called "defaultFaces" or "default" or something similar.

When you try to run paraFoam what error do you run into?

Also, in order to view a OF case in Paraview, you can create an empty .foam file and open that in Paraview.

Hope this helps.

Cheers,
Antimony
