Note on quantitatively correct simulations of the kinetic beam-plasma instability

A large number of model particles is shown necessary for quantitatively correct simulations of the kinetic beam-plasma instability with the clouds-in-cells method. The required number of particles scales inversely with the expected growth rate, as in the kinetic regime only a narrow interval of beam velocities is resonant with the wave.

The impact of initial density profile on protoplanetary disc evolution simulation

In the simulation of protoplanetary disc with a power law density profile a disc instability is detected. The instability arises only with a power law profile and is affected by power index. Thus the impact of initial density profile is large within the employed numerical model.
