Are you referring to access to the cells which have a face on the patch? If it is the case, there is a method to find them, faceCells().

Regards.

Dear Santiago,

maybe you can help me, too. Do you know, by chance, how I can impose a certain value to some cells?

I am using the solver buoyantSimpleFoam, running OF 2.0.1

I have tried - following some thread in this forum - to edit the source.. But the point is that nothing happens. I guess I am editing the wring files.

Thanks,
Samuele

hello,

I am not sure this can help you, but from the 2.1 version, there is a new field source, in which you can set a value ( see explicitSetValue entry).
Only few solver have this, but you can add to the buoyantSimpleFoam solver.

regards,
olivier

Now I'll have a look..
This sounds great! Hope this is what I need.

And I am looking forward to have the 2.1 version installed, then.

Thanks a lot,

Samuele

Samuele, I haven't explored OpenFOAM > 1.7.x so maybe your problem is already solved by the developers as Oliver told us. The way I was thinking about is:

That's good.

Thanks a lot.

As soon as I get the OF 2.1, I'll try to solve this.

Samuele.
