A Multilevel Block Preconditioner for the HDG Trace System Applied to Incompressible Resistive MHD

Sriramkrishnan Muralikrishnan, Stephen Shannon, Tan Bui-Thanh +1

We present a scalable block preconditioning strategy for the trace system coming from the high-order hybridized discontinuous Galerkin (HDG) discretization of incompressible resist…
