In particular, the one derived from the Roe and HLLE solvers, called Rotated-RHLL solver, is extremely robust (carbuncle-free for all possible test cases on both structured and unstructured grids) and accurate (as accurate as the Roe solver for the boundary layer calculation).
In specific, the Rotated-RHLL solver, which was developed from the Roe and HLLE solvers, is remarkably reliable (completely error-free for all possible test cases on both structured and unstructured grids) and exact (as precise as the Roe solver for calculating the boundary layer).
