vpa_advection
moment_kinetics.vpa_advection — Module
moment_kinetics.vpa_advection.update_speed_vpa! — Method
calculate the advection speed in the vpa-direction at each grid point
sourcemoment_kinetics.vpa_advection.update_speed_vpa_DK! — Method
update the advection speed in the parallel velocity coordinate for the case where no moments are evolved independently from the pdf. vpa is unchanged.
sourcemoment_kinetics.vpa_advection.update_speed_vpa_n_evolution! — Method
update the advection speed in the parallel velocity coordinate for the case where density is evolved independently from the pdf; in this case, the parallel velocity coordinate is unchanged.
sourcemoment_kinetics.vpa_advection.update_speed_vpa_n_u_evolution! — Method
update the advection speed in the parallel velocity coordinate for the case where density and flow are evolved independently from the pdf; in this case, the parallel velocity coordinate is the peculiar velocity wpa = vpa-upar
sourcemoment_kinetics.vpa_advection.update_speed_vpa_n_u_p_evolution! — Method
update the advection speed in the parallel velocity coordinate for the case where density, flow and pressure are evolved independently from the pdf; in this case, the parallel velocity coordinate is the normalized peculiar velocity wpa = (vpa - upar)/vth
