scheme
Time integration scheme. GTS marches physical time with this scheme itself, so the scheme sets the run's order of accuracy — only the three-stage TVD Runge-Kutta (SSP-RK3, third order) is admissible.

default 3
Runge-Kutta stage configuration: the three-stage TVD scheme (SSP-RK3), third order in physical time. Spelled either 3 or 'rk third order tvd' — the same scheme either way
