Pressure-Velocity Coupling

  1. Jul 9, 2016 #1
    In Fluent, there are several 'pressure-velocity coupling' algorithms.

    Why are these necessary when, in many fluid mechanics textbooks, it is proposed that for incompressible fluids, an equation for Pressure can be found by taking the divergence of the Navier-Stokes equation, and inverting using the Biot-Savart law?

    ANSYS's documentation package describes in great detail the applications of each solver. It appears most of the reasons you would choose one solver over another relate to the kind of problem you're solving, and the FEA model's parameters.
