Hydrodynamics Adaptive Mesh Refinement Simulator (HAMeRS)

HAMeRS (github here) is an in-house flow solver to provide the capability to simulate compressible single-species and multi-species flows with dynamic mesh refinement technique and high-order methods. The solver is designed with the object-oriented methodology. Parallelization of code, management and storage of data are facilitated by the SAMRAI library, which is a high-performance library for patched-based adaptive mesh refinement (AMR) from Lawrence Livermore National Laboratory (LLNL).

Currently, following features have been implemented:

- Euler and compressible Navier-Stokes solvers

- High-order conservative shock- and interface-capturing WCNS family including the sixth-order localized dissipation WCNS

- Sixth-order finite difference schemes for diffusive/viscous flux in conservative or non-conservative form

- Value, gradient and multiresolution wavelet sensors for identifying regions for refinement

- Single-species, four-equation (assuming isothermal and isobaric equilibria between species) and five-equation (assuming isobaric equilibrium between species) multi-species flow models

- Multi-time stepping with Runge-Kutta schemes
