Quick start guide for beginners, samples, manual & [more...]The Pencil Code is a high-order finite-difference code for compressible hydrodynamic flows with magnetic fields. It is highly modular and can easily be adapted to different types of problems. The code runs efficiently under MPI on massively parallel shared- or distributed-memory computers.
The Pencil Code or equivalent codes have been used for many different applications in a (more or less) astrophysical context. Examples are
