Hi foamers

With rotatingWallVelocity boundary condition on a patch we usually apply zeroGradiant BC on p, which is incorrect. In this case pressure normal gradient is a value which change with time. Hence, if I can calculate the pressure normal gradient value (Which I don't know how to calculate yet) in each time step, can I update it with fixedGradient BC? or do I need to create a new boundary condition which inherit with fixedGradient BC?

I greatly appreciate your ideas and references.

Thank you.
