OPTIMAD Engineering is pleased to announce the publication on SIAM Journal on Scientific Computing of the article Emanuela Abbate, Gabriella Puppo, Angelo Iollo – An asymptotic-preserving all-speed scheme for fluid dynamics and non linear elasticity – vol. 41(5), 2019. In this paper an implicit relaxation scheme is derived for the simulation of multi-dimensional flows at all Mach numbers, ranging from very small to order unity.
The authors use the Bitpit library for the implementation of the computational grid. The hierarchical nature of the grid makes mesh generation, adaptivity and partitioning very efficient and with a low-memory footprint.
