The Pencil Code, a modular MPI code for partial differential equations and particles: multipurpose and multiuser-maintained

The Pencil Code is a highly modular physics-oriented simulation code that can be adapted to wide range of applications. It primarily designed solve partial differential equations (PDEs) compressible hydrodynamics and has lots add-ons ranging from astrophysical magnetohydrodynamics (MHD) meteorological cloud microphysics engineering applications in combustion. Nevertheless, the framework general also applied situations not related or even PDEs, for example when just message passing interface input/output strategies are used. evolve Lagrangian (inertial noninertial) particles, their coagulation condensation, as well interaction with fluid.
