Member Function Documentation

◆ Advance()

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

Performs an integration timestep.

Parameters
dttimestep 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.
