Detailed Description

Module with subroutines for prescribed motion calculations.

This module contains a set of subroutines for updating the state- dependent prescribed motion objects.

Function/Subroutine Documentation

initprescribedvelacc()

subroutine, public motionroutinesmodule::initprescribedvelacc	(	type(motiontype), dimension(:), intent(in)	motions,
		real(dp), dimension(:), intent(inout)	sysVel,
		real(dp), dimension(:), intent(inout)	sysAcc
	)

Inserts prescribed motion values into the system vectors.

Parameters

[in]	motions	Array of all prescribed motions in the model
	sysVel	System velocity vector
	sysAcc	System acceleration vector

Only for prescribed velocities and accelerations. Does nothing for prescribed displacements.

updateprescribedmotionsa()

subroutine motionroutinesmodule::updateprescribedmotionsa ( real(dp), intent(in)  t, real(dp), intent(in)  h, real(dp), intent(in)  beta, real(dp), intent(in)  gamma, real(dp), dimension(:), intent(in)  sysVel, real(dp), dimension(:), intent(in)  sysAcc, type(motiontype), dimension(:), intent(inout)  motions, logical, intent(in)  linearStatic, integer, intent(out)  ierr, integer, intent(in), optional  lpu  )

private

Updates the prescribed motions.

Parameters

[in]	t	Current simulation time
[in]	h	Time increment size
[in]	beta	Newmark time integration parameter
[in]	gamma	Newmark time integration parameter
[in]	sysVel	System velocity vector
[in]	sysAcc	System acceleration vector
	motions	Array of all prescribed motions in the model
[in]	linearStatic	If .true., multi-load case linear static analysis
[in]	lpu	File unit number for debug output of motions from file
[out]	ierr	Error flag

A prescribed motion can be updated either by evaluating the general function connected to it, or by reading new values from the binary file provided. The latter approach is typically used in sub-model analysis.

updateprescribedmotionsb()

subroutine motionroutinesmodule::updateprescribedmotionsb	(	type(motiontype), dimension(:), intent(inout)	motions,
		integer, intent(out)	ierr
	)

Updates the prescribed motions.

Parameters

	motions	Array of all prescribed motions in the model
[out]	ierr	Error flag

This version only (re)evaluates the prescribed motion functions, and is typically used after the initial configuration has been defined in order to ensure that all functions depending on other state variables are up to date before starting the time integration.
