Abstract
We give an overview of the challenges and the current status of our two-dimensional (core collapse) supernova modelling, and present the system of equations and the algorithm for its solution that are employed in our code, and report on our continuing efforts to improve the physics in our supernova code VERTEX as well as its the computational efficiency. We also discuss recent results of simulations performed on the NEC SX-8 at the HLRS, which include the first multi-dimensional general-relativistic neutrino transport simulations—conducted with a new extension of the VERTEX code—as well as simulations of neutron star cooling over several seconds for different nuclear equations of state.
