Wall boundary condition

#1 Unread post by logvinov »

Hi all,
I have a simple question. Can somebody tell me what kind of boundary condition is WALL (in cppdfs)? In particular what kind of bc it sets for a velocity parallel to the wall?

Thanks a lot,
Evgeny

Velocity parallel to the wall depends on your value of gamma2: +1 for free slip, -1 for no slip. gamma2 is set in the ocean.in file.
