Member Data Documentation

timestep

core::Real orrery::sim::RunSettings::timestep = 0

The interval of simulated time one step covers.

There is no default worth having. The right timestep is a property of the configuration, roughly the shortest orbital period in it divided by a few dozen, and a plausible-looking default would produce plausible looking nonsense for any configuration it did not suit.

seed

std::uint64_t orrery::sim::RunSettings::seed = 0

The seed for the sampler that draws the initial conditions.

Recorded even for the analytic configurations, which draw nothing, so that a configuration file's meaning does not depend on which generator it names.
