4.8.3.48. GET_RFLEX_NODETPOS

GET_RFLEX_NODETPOS subroutine returns a position vector for a node of RFlex body. This is an auxiliary subroutine for Modal_Force_Ext.

Table 4.141 Function Name
Language type	Subroutine
FORTRAN	call get_rflex_nodepos(ifbody, NodeSeq, MKID, nMK, TPOS, ErrFlg)
C/C++	get_rflex_nodepos (ifbody, NodeSeq, MKID, nMK, TPOS, &ErrFlg)

Table 4.142 Parameter information
Variable Name	Size	Description
ifbody	int	Sequential id of RFlex body defined in RecurDyn/Solver. This is a related argument with the 5^th argument of Modal_Force_Ext subroutine.
NodeSeq	int	Node sequential id defined in RecurDyn/Solver. This is a related argument with the 6^th argument of Modal_Force_Ext subroutine.
MKID	int[2]	An array of integer type. Each value should be zero or a marker id. 1^st value is defined as base marker. 2^nd value is defined as reference marker.
nMK	int	An integer variable for considering base and reference marker. If nMK is 0, then the subroutine returns a global position vector and an orientation matrix of NodeSeq. If nMK is 1, then the subroutine calculates a position vector considering base marker. If nMK is 2, then the subroutine calculates a position vector considering base and reference marker.
TPOS	double[3]	An array of double precision type. The array size must be 3. 3 values mean a position vector.
Errflg	int	Error flag. If the result of this argument is -1 (means TRUE in Fortran logical value), there is no error. The others mean that there is an error.
