I have some time to put it back to CitcomCU. Can you send your original
code to me?

My VBC at the top boundary is dVr/dr=0 for radial velocity and free-slip
for horizontal velocity. At one time, I want to study the convection
near the base of the mantle without the closed-top boundary conditions,
so I tried to implement the open-top boundary conditions naively.
Thanks for the detailed explanation. That helps alot.
