Content

A finite-volume 2D solver of the compressible magnetohydrodynamic (MHD) equations will be implemented step by step. MHD solvers are valuable tools in order to study the dynamics of astrophysical systems involving magnetic fields by direct numerical simulation. In modern theoretical physics, the need to solve complex, nonlinear and coupled systems of partial differential equations requires basic knowledge of numerical methods. To this end, relevant technical aspects are introduced and implemented interactively with the students, who write their own MHD solver with the assistance of the lecturers. Technical aspects include, but are not limited to: time integration methods, boundary conditions, order of convergence, techniques to maintain the solenoidality of the magnetic field, input/output issues, visualisation of the fields etc. Basic programming knowledge is certainly helpful. While the participants are free to use the programming language they wish, the use of Fortran90 or C is recommended in order to ensure that the lecturers can deliver optimal support in case of numerical problems.
