TOV Perturbations
This is an old textual note which I digitize here because I throw the textual one away. Has to be sorted in accordingly
Plan from an old coding week:
- Trento: Artificial viscosity
- Frankfurt: Perturbed TOV, with THC, FIL
Perturbations:
p = alpha * p_0
rho = rho_0 * (1 + alpha * cos(2pi r/R))
Trento codes:
- Tractor: AMR-3D (=all features, but slow)
- Ferrari: ADER-DG (=prototype, clean, vectorized, fast, but only unigrid and no limiter)
