Hi Forum

I have trouble understanding the use of atmosphere B.C. conditions in the context of interFoam.

How/where can I specify the ambient pressure/atmospheric pressure (101325 Pa) in the damBreak tutorial.

The controlDict located in OpenFOAM-ver/etc/ has some dimensional constants like Pstd, Tstd etc.
Are these used somewhere when I use atmosphere B.C.

Any insight will be helpful and highly appreciated.
