Residual equilibrium schemes for time dependent partial differential equations

The paper about Residual equilibrium schemes for time dependent partial differential equations written in collaboration with Lorenzo Pareschi has been accepted in Computers and Fluids. Yay!

Many applications involve partial differential equations which admits nontrivial steady state solutions. The design of schemes which are able to describe correctly these equilibrium states may be challenging for numerical methods, in particular for high order ones. In this paper, inspired by micro-macro decomposition methods for kinetic equations, we present a class of schemes which are capable to preserve the steady state solution and achieve high order accuracy for a class of time dependent partial differential equations including nonlinear diffusion equations and kinetic equations. Extension to systems of conservation laws with source terms are also discussed.
