A compact high-order and positivity-preserving active flux method for compressible Navier--Stokes equations on Cartesian meshes
This paper develops a compact fourth-order positivity-preserving active flux (AF) method for the one- and two-dimensional compressible Navier--Stokes equations on Cartesian meshes. The method retains the cell averages and shared point values of the standard third-order AF method as its degrees of freedom. To avoid the...
