Read dat file with fortran

Francois

Hello,

I have made a 3D LES simulation and want to read the dat file generated by Fluent with a small Fortran code.

The mesh is structured with hexaedral elements. I have exported the dat file to ascii (node values) but I'm unable to find a good solution to read the variables.

I want someting like this for Nx x Ny x Nz nodes:

I J K X Y Z Variable1 ....

1 1 1 X(1,1,1) Y(1,1,1) Z(1,1,1) V(1,1,1)

1 1 2 X(1,1,2) Y(1,1,2) Z(1,1,2) V(1,1,2)

. . .

1 1 Nz X(1,1,Nz) Y(1,1,Nz) Z(1,1,Nz) V(1,1,Nz)

1 2 1 X(1,2,1) Y(1,2,1) Z(1,2,1) V(1,2,1)

1 2 2 X(1,2,2) Y(1,2,2) Z(1,2,2) V(1,2,2)

. . .

1 Ny Nz X(1,Ny,Nz) Y(1,Ny,Nz) Z(1,Ny,Nz) V(1,Ny,Nz)

. . .

Nx Ny Nz X(Nx,Ny,Nz) Y(Nx,Ny,Nz) Z(Nx,Ny,Nz) V(1,Ny,Nz)

Any idea will be helpfull. Thank's in advence
