A shock-adaptive Godunov scheme based on the generalised Lagrangian formulation
Based on the generalized Lagrangian formulation (GLF), the Godunov scheme yields a high accuracy. By the use of coordinate streamlines in the GLF, the slipline -- itself a streamline -- is resolved crisply. Infinite shock resolution is achieved through the splitting of shock-cells. An improved entropy-conservation formulation of the governing equations is also proposed for computations in smooth flow regions.
