Detailed Description

A stationary solution.

The stationary solution is featured by the lack of velocity on the system, i.e. the system positions are integrating directly from the accelerations

Constructor & Destructor Documentation

◆ StationaryScheme()

moordyn::time::StationaryScheme::StationaryScheme	(	moordyn::Log *	log,
		moordyn::WavesRef	waves
	)

Constructor.

Parameters

log	Logging handler
waves	Waves instance

Member Function Documentation

◆ Error()

real moordyn::time::StationaryScheme::Error ( ) const

inline

Get the error computed at the last time step.

Returns: The error, StationaryScheme::_error

Here is the caller graph for this function:

◆ NStates()

size_t moordyn::time::StationaryScheme::NStates ( ) const

inline

Compute the number of state variables.

This can be used to renormalize the error, so it makes more sense to the final user

Returns: The number of state variables

Note: Each entry on the states is considered a single variable, that is no matter if the state is a scalar, a vector or a quaternion, it is considered as a single entry

Here is the caller graph for this function:

◆ Step()

void moordyn::time::StationaryScheme::Step ( real & dt )

virtual

Run a time step.

This function is the one that must be specialized on each time scheme

Parameters

dt Time step

Reimplemented from moordyn::time::SchemeBase< 2, 1 >.

Here is the call graph for this function:
