Detailed Description

Problem generator for non-linear streaming instability in stratified disks.

PURPOSE: Problem generator for non-linear streaming instability in stratified disks. This code works in 3D ONLY. Isothermal eos is assumed, and the value etavk/iso_sound is fixed. MPI domain decomposition in x is allowed, but not in z.

Perturbation modes:

Should be configured using --enable-shearing-box and --with-eos=isothermal. FARGO is recommended.
