Improving the scalability of a high-order atmospheric dynamics solver based on the deal.II library
Giuseppe Orlando, Tommaso Benacchio, Luca Bonaventura
We present recent advances on the massively parallel performance of a numerical scheme for atmosphere dynamics applications based on the deal.II library. The implicit-explicit disc…
Efficient and scalable atmospheric dynamics simulations using non-conforming meshes
Giuseppe Orlando, Tommaso Benacchio, Luca Bonaventura
We present the massively parallel performance of a -adaptive solver for atmosphere dynamics that allows for non-conforming mesh refinement. The numerical method is based on a Di…
Asymptotic-preserving IMEX schemes for the Euler equations of non-ideal gases
Giuseppe Orlando, Luca Bonaventura
We analyze schemes based on a general Implicit-Explicit (IMEX) time discretization for the compressible Euler equations of gas dynamics, showing that they are asymptotic-preserving…
