Coordinate Singularities in Harmonically-sliced Cosmologies [PDF]
, 2000 Harmonic slicing has in recent years become a standard way of prescribing the lapse function in numerical simulations of general relativity. However, as was first noticed by Alcubierre (1997), numerical solutions generated using this slicing condition ...

Moving mesh finite difference solution of non-equilibrium radiation diffusion equations [PDF]
, 2018 A moving mesh finite difference method based on the moving mesh partial differential equation is proposed for the numerical solution of the 2T model for multi-material, non-equilibrium radiation diffusion equations. The model involves nonlinear diffusion

Stationary solutions of incompressible viscous flow in a wall-driven semi-circular cavity
Acta Polytechnica, 2021 Stationary numerical solutions of incompressible viscous flow inside a wall-driven semicircular cavity are presented. After a conformal mapping of the geometry, using a body-fitted mesh, the Navier-Stokes equations are solved numerically.
