boundary conditions
 
my boundary conditions cannot be seen in fluent,wen i bring a mesh file from icem cfd after meshing it..what could be mistake or problem?

Do you mean, that they are not visible under "boundary conditions" in Fluent? Then, I am 99% sure you did something wrong in ICEM.
What do you use for meshing in ICEM? Hexa with blocking?

thanks for ur reply...
i used Hexa mesh (free mesh)...when i tried to do some model example in ICEM..its coming correctly in FLUENT.. but my actual model getting some problem in boundary condition while transferring it from ICEM to FLUENT...

pls help me

So what exactly is the problem?

you don't have shell in your boundaries . associate face to surface to solve the problem...

the procedure i carried out...
1.i did modelling in CATIA and imported the surface and curves as IGES into ICEMCFD(its 2D).

2.Then i created parts and shadows for meshing.

3.Afta tat i created body in the parts were water flows.

4.then i shell meshed it and computed with a surface mesh.

5.i saved the mesh file and took it to fluent and there i got the problems.the boundary conditions were not visible...

i attach the pics of the mesh that i created and the problem that i faced in fluent.Attachment 20059Attachment 20059
