transfer of solution from one script to another

Asked by Hossein Nili

Hi

I tried to find this from the documentation but couldn't - may be I am searching for the wrong terminology. I'd be very thankful if you could help me out here:

I solve a PDE using a FEniCS script, and find a solution u. What I wish to do is to export/transfer this solution to another script which takes u as "input" (i.e. known) and solves another PDE in terms of another variable based on this given input.

Any help please?

Many thanks,

Look at the Stokes and advection-diffusion demos in DOLFIN. The
computed Stokes velocity from one demo is used as input to the
advection-diffusion demo.
