cannot export mesh file from Gambit
 

hey, i am new comer here.

i was trying to export a meshed 2D channel file.
but gambit gave me there error messages when i click export-->mesh

error: continuum or boundary condition specified on entity edge.1 is invalid for fluent 6

if i dont specify any boundary conditions or continuum type, the meshed file can be exported successfully. so the problem must occur when defining boundary condition....
but i dont know exactly what is wrong...
can anyone help me?

check your bondary condition on Edge 1, may be the boundary u r looking for is not avlaiable in Fluent 6, if you do not specify any boundary, they are exported as wall boundary so Gambit did not show any warning.
