◆ Advance()

void chrono::ChTimestepperRungeKuttaExpl::Advance ( const double dt )

overridevirtual

Performs an integration timestep.

Parameters

dt	timestep to advance

Implements chrono::ChTimestepper.

◆ GetType()

virtual Type chrono::ChTimestepperRungeKuttaExpl::GetType ( ) const

inlineoverridevirtual

Return type of the integration method.

Default is CUSTOM. Derived classes should override this function.
