Function Documentation

◆ Particles_Dust_ConservativeFeedback()

void Particles_Dust_ConservativeFeedback ( Data_Arr  U,
Data_Arr  Fdust,
double  dt,
RBox box 
)

Conservative feedback:

( v)_g -= dt*rho(dust)*F

Here F is the acceleration drag.

◆ Particles_Dust_StatesSource()

void Particles_Dust_StatesSource ( Sweep sweep,
Data_Arr  Fdust,
double  dt,
int  beg,
int  end,
Grid grid 
)

Add drag source term to L/R sweeps during the predictor step of CTU algorithm.
