BC implementation in rhoSonicFoam

srinath · July 10, 2008, 08:27

Hello

I am looking at the code of rhoSonicFoam, and i can't spot any place where the BC's are applied.
It seems to work quite magically.
I find this quite perplexing. Any help will be much appreciated as i have been staring at the code for a whole day.

Thanks
Srinath

i believe the bcs are applied when you call solve

Srinath,

The boundary conditions are read when you create the fields (see file createFields.H). Each field holds the boundary condition that are specified in the corresponding file (0/U, 0/p, ...).
And as explained by kshitij, when you call solve on a given equation, the boundary conditions, associated to the field the equation refers to, will be taken into account.

I hope it helps.
If you want more details, just ask or start reading the code of the fields objects.
