Two Level Preconditioner of Steady Stokes-Brinkman Equation with Jumps in Coefficients
Original language description
We suggest to solve saddle point system, which arises from mixed finite element method for the presented Stokes-Brinkman model, by GMRES solver with preconditioner which leads to solving symmetric positive definite system in every GMRES iteration. This preconditioner is ill-conditioned, hence we use several types of approximate inverse as preconditioning for this symmetric positive definite system. We present numerical results for an incompressible flow problem in a domain with jumps in coefficients.
