I'm using Gambit software to create 2-D flow test cases grids for the solvers I develop in my master thesis. I want to export the mesh in an easy format in order to read it back in my solvers. I tried the *.msh files but it seemed strange and i couldn't find any materials about it. I will appreciate any help in this issue.

Thanks,

I already have a technique that works now but i think it is too silly and time consuming. the steps are as follows:

1) export *.msh files from gambit 2) open fluent (don't ask why lol) and read the *.msh file 3) export the *.cas file from fluent 4) open tecplot (don't say why again lol) import the *.cas file 5) export the grid zone in a tecplot format, finally you can read the mesh from the tecplot ASCII file.

the main problem that still exist is the boundary points!!

Try *CGNS which is the nearest to a standard mesh interface that there currently is.

Dear Guirguis, Here the format of Gambit *.msh file ------------------------------------- ( point 1 to np) All x and y coordinates..

Face (Edge) ( 1 to nf)... All are Hexa decimal format

out of that

(3 1 to n1)--- Some boundary condition for ex:: wall (iden no :3) totalnodes in that edge, 1st node, 2nd node, outcell(R),Incell(L)... ... then other BCs continues.. (8 n5 to nf)..(Here 8 is interior edges identification no) ... atlast (1 to nc) nc- total no of cells.. Then idea abt Various BCs and their numbering...

If you want to know more.. Plz mention Ur id..
