Hello All,

The following are copied from Cheng Ming D2Q9 LBM FORTRAN code, to show a square obstacle in a channel, using Tecplot. I have tried to write a 3D block inaside a 3D channel but I cannot do it. If anybody has any idea, please share it, just like the follwing part, it will be very helpful for me.

WRITE(11,*) ‘GEOMETRY M=GRID, FC=WHITE,F=POINT’
WRITE(11,*) ‘2’

WRITE(11,*) ‘4’

```
WRITE(11,*) x1,y1
WRITE(11,*) x1,y2
WRITE(11,*) x2,y2
WRITE(11,*) x2,y1
WRITE(11,*) '2'
WRITE(11,*) x1,y1
WRITE(11,*) x2,y1
```

!-------------------------------------------------------

Sincerely yours

Tanu
