Matrix-free GPU-accelerated saddle-point solvers for high-order problems in $H(\mathrm{div})$

Will Pazner, Tzanio Kolev, Panayot Vassilevski

This work describes the development of matrix-free GPU-accelerated solvers for high-order finite element problems in $H(\mathrm{div})$. The solvers are applicable to grad-div and D…
