the momentum equation without

the momentum equation without buoyancy:
LHS = -grad(p)

with buoyancy:
LHS = -grad(p) + rho g

forgot about that little detail, the two "rho g" cancel out

thanks david

grad(gh) = grad(g & mesh.C())

grad(gh) = grad(g & mesh.C())
results in a constant gradient for a uniform mesh in direction of g

so, for the moment i share shaun's confusion
