F_adv

dustpy.std.dust.F_adv(sim, Sigma=None)[source]

Function calculates the advective flux at the cell interfaces. It is linearly interpolating the velocities onto the grid cel interfaces and is assuming vi(0, :) = vi(1, :) and vi(Nr, :) = vi(Nr-1, :).

Parameters:

  • sim (Frame) – Parent simulation frame

  • Sigma (Field, optional, default : None) – Surface density to be used if not None

Returns:

Fi – Advective mass fluxes through the grid cell interfaces

Return type:

Field
