About the Pencil Code

The Pencil Code is a highly modular and higher-order finite-difference code for compressible hydrodynamic flows with magnetic fields, particles and chemical species, for Cartesian as well as curvilinear geometries, written predominantly in Fortran. The work on the code was initiated during the "Helmholtz Summer School on Super-computational Astrophysics" held in Potsdam (2001). Since then the Pencil Code has been used for different applications demonstrating its versatility. In the astrophysical context, few examples are: Turbulence simulations, astrophysical dynamos, radiative magnetohydrodynamics, self gravity and planetesimal formation, gravitational waves, interstellar dust etc. The code is hosted live at gitHub (https://github.com/pencil-code) with over 200 users, and about 80 developers and growing as anyone interested in using the code is welcome to join the consortium. Please see http://pencil-code.nordita.org/ for more information on downloading and using the code.

About the meeting

The annual pencil code user meeting has been organised since 2005 for,

• Keeping track of the continuing development work on the code,
• The science achieved using the code,
• To make it more relevant to researchers around the world.
• To foster collaborations, and
• To introduce the code to new users

Lectures for new users including topics:

• Concept of pencils, cache efficiency, storage arrays,
• Grids, finite differencing and time stepping,
• Plug-and-play physics and particle modules,
• IO modules,
• Post processing using Python, Mathematica, and
• Tutorials

• Registration and abstract submission opens: 10 March, 2022
• Registration closes: 15 April, 2022 (Deadline extended to 28 April)
• Meeting dates: 4-10th May, 2022
