Implementation of the Vanka-type multigrid solver for the finite element approximation of the Navier-Stokes equations on GPU
Original language description
We present a complete GPU implementation of a geometric multigrid solver for the numerical solution of the Navier?Stokes equations for incompressible flow. The approximate solution is constructed on a two-dimensional unstructured triangular mesh. The problem is discretized by means of the mixed finite element method with semi-implicit timestepping. The linear saddle-point problem arising from the scheme is solved by the geometric multigrid method with a Vanka-type smoother. The parallel solver is basedon the red?black coloring of the mesh triangles. We achieved a speed-up of 11 compared to a parallel (4 threads) code based on OpenMP and 19 compared to a sequential code.
