navier stokes demo in 3d - FEniCS Q&A - FEniCS Project

TīmeklisConveniently there is a FEniCS demo available for solving the Stokes equations in a three-dimensional cubic domain. In this demo the velocity and pressure are solved using a coupled system of equations. That is, both equations in (47) are solved simultaneously as opposed to in a segregated, sequential manner. The Stokes equations as formulated above result in a system of linear equations that is not positive-definite. Standard iterative linear solvers typically fail to converge for such systems. Some care must therefore be taken in preconditioning the systems of equations.
