Dear All,

My c++ is rusty so here the question:
in pEqn.H there is a statement:
p== p_rgh + rho*gh;
To my knowledge this gives true or false, but it is not assigned to anything.
It is an empty statement unless == is redefined somewhere (where?).
But why is a few lines down p_rgh = p - rho*gh; and not p_rgh == p-rho*gh;
OF170 and OF171

i guess!
== isnot equality here, it assigns all domains include boundary condition from left side to right side!!!!
but = just copy internalField values!
