Function to extrapolate the new pressure boundary condition. Based on the velocity field and on the advection term. Acceleration term is also computed. This routine is a general one for 2d and 3D application and it can be called directly from velocity correction scheme. Specialisation on dimensionality is redirected to the CalcNeumannPressureBCs method.
