MRN_distribution

dustpy.std.dust.MRN_distribution(sim)

Function calculates the initial particle mass distribution. The parameters are taken from the Simulation.ini object.

Parameters:

sim (Frame) – Parent simulation frame

Returns:

Sigma – Initial dust surface density

Return type:

Field

Notes

sim.ini.dust.aIniMax : maximum initial particle size sim.ini.dust.d2gRatio : initial dust-to-gas ratio sim.ini.dust.distExp : initial particle size distribution n(a) da ∝ a^{distExp} da sim.ini.dust.allowDriftingParticles : if True the particle size distribution will be filled up to aIniMax, if False the maximum particle size will be chosen such that there are no drifting particles initially. This prevents a particle wave traveling though the simulation, that is already drifting initially.
