The Jupiter Code

Jupiter is a mutidimensional astrophysical hydrocode. It is based on a Godunov method, and it is parallelized with MPI. The mesh geometry can either be cartesian, cylindrical or spherical. It allows mesh refinement and includes special features adapted to the description of planets embedded in disks and nearly steady states. A comprehensive list of its characteristics can be found here.

Timestep information log
11 April 2008, by Frederic Masset
Lines in the info.log file which begin with [@] contain the following information:
The date
The next output number
The number of DT integrations already performed
The number of hydro time steps performed
The subcycling string (to which we append a ’2’ (we have therefore a single ’2’ if there is no refinement)
The approximative gain w.r.t. no subcycling
The approximative gain w.r.t. full (...)
Properties of the unperturbed disk
8 January 2008, by Frederic Masset
The equations that control the hydrostatic equilibrium of the unperturbed disk in spherical coordinates are: $$-\frac\partial_r(\rho c_s^2)\rho+r\sin^2\Omega^2-\fracGM_*r^2=0$$ and $$-\frac 1r\frac\partial_\theta(\rho c_s^2)\rho+r\sin\theta\cos\theta\Omega^2=0$$
