Howdy Foamers:
I am wondering which way the patch normal of the fixedGradient BC is heading, into the flow domain, or point out of the flow domain? Thanks in advance, Gerry. |

Howdy folks:
I managed to run a very quick test. Indeed, the gradient acts in the direction of the normal, and the normal is positive pointing out of the boundary patch. Gerry. |
