vice.singlezone.dt

Type : real number

Default : 0.01

The timestep size in Gyr to use in the integration.

Note

For fine timestepping, this affects the total integration time with a \(dt^{-2}\) dependence. For coarse timestepping, the integration time is approximately constant, due to it being dominated not by timestepping but by write-out.

Example Code

>>> import vice
>>> sz = vice.singlezone(name = "example")
>>> sz.dt = 0.02
>>> sz.dt = 0.005
