Encountering an error while simulating pipe in the box problem

Hello,
I am using Professional add-on. I have encountered the following error while running the simulation of Pipe in the Box problem,
"Foam fatal error: This mesh contains patches of type empty but is not 1D or 2D by virtue of the fact that the number of faces of this empty patch is not divisible by the number of cells."
I think it has got to do with editing certain mesh conditions, please help me out.
Thanking you in anticipation,
Balaji.

All faces require a boundary condition

That error usually indicates that you have missed assigning one or more boundary conditions.

Thanks again

Yes it worked! I removed wall boundary conditions while undoing wrongly selected symmetry plane and never realized it.
