Is it possible to use the grid (generated using GAMBIT) in structured FVM source code? Is so, how ? Thanks...

yes it is possible, and fluent does this very well.

:-D

I guess you have to export the mesh file as Neutral File, this is a text format, you can read it using any text editor, but if you have GAMBIT, why not use the FLUENT solvers, they are base on FV

I know FLUENT & GAMBIT but I want to use the GAMBIT grid in own FVM code and exporting the mesh files dont gives the readable file.

it does give u a readable file, i do read fluent mesh in my code and its pretty easy to do. you can read fluent manual about the details of grid format. the only thing tht you need to do is, to decide after reading it how you are going to store and use in your code, this part takes little planning and varies with code to code.

When setting the boundary conditions, you have to choose general solver instead of the fluent solver. Gambit will then write a .neu file. The .neu format is described in the c appendix of the gambit manual.
