Hello Foamers!

I'm trying to simulate supersonic nozzle which is designed for M = 3, 4.5, 6

For 2D simulation of axisymmetric case, i made a mesh of wedge of nozzle with one cell thick, angle of 5 degree.

then, i used ideasUnvToFoam command, and edited the boundary condition for the wedge face to 'wedge'

and checkMesh makes the error below

How can i fix this problem?

I thought my mesh is good and fine enough. :<

i tried to attach my UNV file but 4.22mb is over the site's limit, so if you want
to check my UNV file tell me your email. i'll send you it right away


THANKS <3

Hi.

Could you please explain how you got this mesh ? I am trying to simulate the flow in a supersonic nozzle as well. Unfortunately, I can't find how to do it with SALOME.
