Alpaca is a MPI-parallelized C++ code framework to simulate compressible multiphase flow physics. It allows for advanced high-resolution sharp-interface modeling empowered with efficient multiresolution compression. The modular code structure offers a broad flexibility to select among many most-recent numerical methods covering WENO/T-ENO, Riemann solvers (complete/incomplete), strong-stability preserving Runge-Kutta time integration schemes, level set methods and many more.

waLBerla (widely applicable Lattice Boltzmann from Erlangen) is a massively parallel framework for multi-physics applications. Besides its original objective, Lattice Boltzmann solvers for hydrodynamics, it now contains modules for other applications like Multigrid and rigid body dynamics as well. Great emphasis is placed on the interoperability between the modules, in particular, the fluid-particle coupling. It scales from laptops to current and future supercomputers while maintaining near-perfect efficiency.
Main developer: LSS @ FAU
