Abstract:
We discuss the efficient implementation of a high-performance second-order collocation-type finite-element scheme for solving the compressible Euler equations of gas dynamics on unstructured meshes. The solver is based on the convex limiting technique introduced by Guermond et al. (SIAM J. Sci. Comput. 40, A3211–A3239, 2018). As such it is invariant-domain preserving, i. e., the solver maintains important physical invariants and is guaranteed to be stable without the use of ad-hoc tuning para...     »
