Does anyone have a subroutine in Fortran 90 that writes the grid and the rho,u,v,w,p variables from a 3D code on a structured grid in paraview format?

you can try this one:

the routines are implemented to write files in the Ensight6 format but Paraview can read it without any problem.

in Ensight format you'll have to write the following files:

geometry (*.geo)

results (*.vec or *.scl)

and case where you'll point the previous files (for more details see the pdf included in the zip)

Renato.

Great! Many thanks!

then how to write the geometry file regards
