2D model was defined, geometry is simple rectangle which is left angle is divided to three parts in the middle of the left angle, b.c defined as pressure head=0.8 (attached the geometry)
and the other angles were defined as pressure head= 0.0
Solved model
for the middle part that defined pressure head as constant value, cross section was plotted, but why the pressure head after solving the problem is not constant:( changing from 0.4-0.8) for the ends of the special part of angle?(attached cross section)
eager to hear your comments.
