Motivations: climb<strong>in</strong>g up dimensions<br />
Results from 1D GR simulations with detailed Boltzmann transport:<br />
<strong>in</strong> general, no SN <strong>explosion</strong>!<br />
Suggestion:<br />
high dimensions can provide new macrophysics (convection, rotation,<br />
magnetic fields . . . ) which can help stars to explode!<br />
Problem:<br />
full Boltzmann ν transport is memory and CPU-time too expensive<br />
Avaiable solution:<br />
development <strong>of</strong> approximated methods to model ν transport<br />
computationally simpler and cheaper<br />
physically motivated and effective<br />
