class ansys.stk.core.stkobjects.astrogator.RungeKutta2nd3rd#

RK2nd3rd Numerical Integrator.

Overview#

Properties

`initial_step`	Get or set the initial step. Uses time dimension.
`use_fixed_step`	True if running in fixed-step mode.
`use_max_step`	Whether or not to enforce the maximum step.
`use_min_step`	Whether or not to enforce the minimum step.
`max_step`	Get or set the maximum step size to allow (absolute value). Uses Time Dimension.
`min_step`	Get or set the minimum step size to allow (absolute value). Uses Time Dimension.
`max_relative_err`	Get or set the maximum relative error used to control step size. Dimensionless.
`max_absolute_err`	Get or set the maximum absolute error; Also used if relative scale is too small. Dimensionless.
`high_safety_coefficient`	Get or set the ‘safety’ coefficient used to decrease step size if the error is too high. Dimensionless.
`low_safety_coefficient`	Get or set the ‘safety’ coefficient used to increase step size if the error is too low. Dimensionless.
`error_control`	Get or set the error control method.
`max_iterations`	Get or set the maximum iterations. Dimensionless.
