invalid entity error
 

While trying to export the gambit file as a *.msh, I receive this error:

WARN: Continuum Entity water does not contain any valid entity and is not written

No entities were found for mesh export.

What am I not doing, to receive such an error? I have modeled a 2D geometery, meshed it, and applied Boundary and Continuum Conditions.

Please Help

Re: invalid entity error
 

so did you create your face, and then after all did you set the boundaries?
