Streaming instability as presented in Mignone et al (2019). Configurations should be compiled with –with-sb and –with-fargo.
We set the resolution to 64, one particle per cell. The particle stopping time is tau_s = 0.1 for all cases.

Setup #09,#10 is employed for nonlinear evolution. The configuration is for very small runs. For proper study increase tstop to 80 and set Nparticles to 9 (per cell).
Setup #10 has low resolution and does not show instability (unless higher resolution is employed).
