problem with flow over a rectangle

yann

hi

i am trying to study the flow over a rectangle (with round cornerat the end). because of the symetry, i should have the same velocity profile on each side, but i don't!!!! how is that possible. i am working with a turbulent flow (k espilon).

i also try to work on a 3D model, with a geometry a little bit more complicated, and i don't managed to mesh it with gambit. i would like to know if i can send it to someone to have a look and give some hints.

thank you for help yann
