ERROR Message. What does it mean?
 

Hi.

I am trying to mesh long horizontal pipe that extend about 300ft. / ~93m.
It has branch line coming of the sides.

I am attempt to apply a tri-pave mesh on the surface.
However.. I keep getting an error:

ERROR: Assertion failed in FacePrepTool.cc, line 396: test valence >= min valence while meshing face. 482.
