Import problem in fluent GRD file
 
Dear Friends
I am new to Fluent-Gambit. I am doing the tutorials of mixing elbow where I am creating mesh for mixing elbow pipes. The mesh is created using fluent 4 solver setting.
Now I exported the mesh as elbow.GRD but when I am trying to import that file into fluent its not loading the grid giving errors.

Any help would be appreciated.

Hi
If my memory is right I think, the elbow is 2D. Then while exporting mesh , be sure to select the 2D option button.

Try exporting the design as a MSH format rather than GRD, and check the "export as 2D" box.

Can you help me
 
Q1 Any one do for me mesh file (mesh or dbs I want to calculate surface Nusselt number in for downstream ( near the wall )in expansion pipe with turbulent fluid flow the dimension
Small pipe UN heated
Diameter 0.0254 m and width 1.2192m
Big pipe heated
Diameter 0.09525 m and width 1.7145m
Q2 in fluent which turbulent model suitable to my case


thank you
