moment_kinetics.vpa_advection.update_speed_default! — Methodmoment_kinetics.vpa_advection.update_speed_linear — Methodupdate the advection speed dvpa/dt = const*(vpa + L/2)
moment_kinetics.vpa_advection.update_speed_n_p_evolution! — Methodupdate the advection speed in the parallel velocity coordinate for the case where density and pressure are evolved independently from the pdf; in this case, the parallel velocity coordinate is the normalized velocity vpahat = vpa/vth
moment_kinetics.vpa_advection.update_speed_n_u_evolution! — Methodupdate 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
moment_kinetics.vpa_advection.update_speed_n_u_p_evolution! — Methodupdate 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 wpahat = (vpa - upar)/vth
