Stable and asymptotic preserving space-time discretizations of a linear kinetic transport equation in diffusive scaling
Anita Gjesteland, Sigrun Ortleb, Salim Elghawi +1
We develop an unconditionally energy-stable tensor-product space-time discretization framework for the solution of a linear kinetic transport equation in one space dimension. The k…

Entropy-stable in- and outflow boundary conditions for the compressible Navier-Stokes equations
Magnus Svärd, Anita Gjesteland
We propose inflow and outflow boundary conditions for the compressible Navier-Stokes equations and prove that they allow a priori estimates of the entropy, mass and total energy. F…
