Compute an "a priori" hydrostatic pressure and its gradient associated before the Navier Stokes equations (prediction and correction steps navstv.f90).
This function computes a hydrostatic pressure
and using the mass equation as following:
with:
finally, we resolve the simplified momentum equation below:
with the diffusion coefficient (
with a Neumann boundary condition on the hydrostatic pressure:
(see the theory guide for more details on the boundary condition formulation).
