Function/Subroutine Documentation

◆ initsam()

subroutine samsolvermodule::initsam	(	type(samtype), intent(out)	sam,
		integer, intent(out)	ierr
	)

Initializes the SAM data structure for fedem_solver.

Parameters

[out]	sam	Data for managing system matrix assembly
[out]	ierr	Error flag

◆ initsam_constraints()

subroutine samsolvermodule::initsam_constraints	(	type(motiontype), dimension(:), intent(inout)	motions,
		type(masterslavejointtype), dimension(:), intent(inout), target	joints,
		type(higherpairtype), dimension(:), intent(inout)	higherPairs,
		integer, dimension(:), intent(inout)	mpar,
		integer, dimension(:), intent(in)	madof,
		integer, dimension(:), intent(inout)	msc,
		integer, dimension(:), pointer	mpmceq,
		integer, dimension(:), pointer	mmceq,
		real(dp), dimension(:), pointer	ttcc,
		integer, dimension(:), pointer	mpreac,
		integer, intent(out)	ierr
	)

Initializes linear coupling arrays in SAM.

Parameters

	motions	All prescribed motions in the model
	joints	All joints in the model
	higherPairs	All higher pair objects in the model
	mpar	Matrix of parameters
[in]	madof	Matrix of accumulated DOFs
[in]	msc	Matrix of status codes
[out]	mpmceq	Matrix of pointers to MCEQs
[out]	mmceq	Matrix of constraint equation definitions
[out]	ttcc	Table of constraint equation coefficients
[out]	mpreac	Matrix of pointers to reaction forces
[out]	ierr	Error flag

This subroutine initializes the SAM arrays MPMCEQ, MMCEQ and TTCC based on Motion and Joint data. The array TTCC is here only initialized to zero (except for the higher pair constraints). The numerical values of the constraint equations are calculated by the subroutines updateDependencies and updatePrescribedMotions. The array MPREAC is also initialized by this subroutine based on Motion data and the fixed DOFs.
