Fixed Value Timestep

time::timestep_method = "given"
time::timestep        = 0.1

Calculate Static Timestep Based on Grid Spacings

The following parameters set the timestep to be 0.25

grid::dx    = 0.5
grid::dy    = 1.0
grid::dz    = 1.0
time::timestep_method = "courant_static"
time::dtfac = 0.5
