Sorry Stephane, another thought about the question of my last e-mail.
In a forward time dependent scheme, is it possible to play with the size of
the time step to improve accuracy?
Thank you again!

Hello Stephane
First of all thanks for your mail!!. I have just recompiled the latest CVS
version of 1pre9 and tried the smesh utility. Everything works wonderfully,
Thanks!!
About the ofstreams that is great!. I had however gone around the problem
using awk. It is amazingly powerful and very easy to learn and use. You can
pipe (not for windows users i am afraid) the printing to console of ff3d to
awk and then, with 3 or 4 lines of code you can sort out an enormous amount
of things. I will try to give a try to the ofstream utility later.
The variables are local now. So far i have not tried to refine the mesh so
it is not clear to me now how this should be done... How does it help the
variables being local??
And i would like to take the opportunity to raise a question...What is the
best approach to improve the numerical accuracy of ff3d computations?. Is it
always to use a finer mesh (larger computing cost)?
As always thanks for your support and help.
Emilio
