Abstract: Summary We simulate the propagation of very light astrophysical jets with density contrasts between 10−1 and 10−4 including magnetic fields into the intracluster medium on the galaxy cluster scale, using the magnetohydrodynamic code NIRVANA on the NEC SX-6 and SX-8. The code runs very efficiently and enables us to perform simulations in both axisymmetry as well as full 3D, using both shared-memory and MPI parallelization. Simulations further supported a stabilization of the contact surface by magnetic fields, as seen in low-frequency radio observations. Efficient storage methods for high time resolution runs as well as visualization methods were implemented and allow in-depth analysis of velocity and magnetic fields.
