Function/Subroutine Documentation

initiatesystem()

subroutine initiatesystemtypemodule::initiatesystem	(	type(systemtype), intent(out)	sys,
		type(enginetype), dimension(:), intent(in)	engines,
		integer, intent(in)	tIncEngineId,
		real(dp), dimension(3), intent(in)	wFac,
		integer, intent(out)	err
	)

Initializes system level model data from the command-line arguments.

Parameters

[out]	sys	System level model data
[in]	engines	All general functions in the model
[in]	tIncEngineID	Base ID of the function returning time step size
[in]	wFac	Weighting factors for the DOFs of different kind, wFac(1)=translations, wFac(2)=rotation, wFac(3)=generalized DOFs
[out]	err	Error flag

initiatesystem2()

subroutine initiatesystemtypemodule::initiatesystem2	(	type(samtype), intent(in)	sam,
		type(systemtype), intent(inout)	sys,
		integer, intent(out)	err
	)

Allocates the system vectors and Newton matrix.

Parameters

[in]	sam	Data for managing system matrix assembly
	sys	System level model data
[out]	err	Error flag

This subroutine allocates all the system vectors (displacement, velocity, acceleration and force vectors) and the system Newton matrix. The dynamic convergence tolerances are also initialized.

inittimestepping()

subroutine initiatesystemtypemodule::inittimestepping	(	type(systemtype), intent(inout)	sys,
		integer, intent(out)	err
	)

Initializes the time stepping before starting integration loop.

Parameters

	sys	System level model data
[out]	err	Error flag

In case a dynamic ramp-up is specified, the actual start time is shifted back the duration of the ramp-up, such that the start of the actual simulation will happen at the same time as without ramp-up. The number of ramp-up increments is used to define the time increment size during the ramp-up stage. The ramp function is a smooth trajectory function.
