Hi, Just a question:
If I prescribe a mixed bc for a e.g. vector quantity as U, is it possible to modify at runtime the values associated with the value,gradient,blending?

I mean if initially I have a zero gradient condition:
outflow
{
// type zeroGradient;
type mixed;
refValue nonuniform List<vector>
20
(
(0 0 0)
...
);
refGradient nonuniform List<vector>
20
(
(0 0 0)
...
);
valueFraction nonuniform List<scalar>
20
(
0
...
);
}

...and after some runtime I get at position 5 in my patch a value for U that I want to keep, is it possible to set the 5th value in refValue list to what I want and the 5th value in valueFraction list to 1? Of course doing the corresponding changes in the boundary condition for p...
any suggestions?
Cheers,

Hi,
I am really stuck with this. I will try to reformulate my question, maybe I have better luck.
If I have a vector or a scalar with a boundary condition of type "mixed", is there a way of changing the refValue, refGradient and valueFraction at runtime? Which would be the syntax do do this?
Thanks,
Radu
