First order hyperbolic approach for Anisotropic Diffusion equation
Amareshwara Sainadh Chamarthi, Hiroaki Nishikawa, Kimiya Komurasaki
In this paper, we present a high order finite difference solver for anisotropic diffusion problems based on the first-order hyperbolic system method. In particular, we demonstrate…

High-order upwind and non-oscillatory approach for steady state diffusion, advection-diffusion and application to magnetized electrons
Amareshwara Sainadh Chamarthi, Kimiya Komurasaki, Rei Kawashima
Steady state simulations} of magnetized electron fluid equations with strong anisotropic diffusion based on the first-order hyperbolic approach is carried out using cell-centered h…
