HiFiLES Dev. Ver. 0.1 contains the following capabilities:
- High-order compressible Navier-Stokes and Euler equations solver in 2D and 3D with support for triangular, quadratic, hexahedral, prismatic, and tetrahedral elements. Implementation for spatial orders of accuracy 2 through 4 have been verified.
- Numerical scheme: Energy-Stable Flux Reconstruction.
- Time advancement: explicit time-stepping with low-storage RK45 method (4th order) or forward Euler (1st order). Local time-stepping when running on CPUs.
- Boundary conditions: Wall: no-slip isothermal, no-slip adiabatic, and symmetry (slip wall). Inflow and outflow: characteristic, supersonic, subsonic. Periodic.
- High-order surface representation.
- Mesh format compatibility: neutral (.neu) and Gmsh (.msh).
- Large Eddy Simulation: Sub-grid Scale Models: Smagorinsky, WALE, similarity, and combinations of these. Wall models: log-law, three-layer Breuer-Rodi.
- Parallelization: MPI, and GPU (strong scalability 88% of ideal for up to 16 GPUs; weak scalability above 90% of ideal for up to 16 GPUs)
