Description |
|
ifbody |
int |
Sequential id of RFlex body defined in RecurDyn/Solver. This is a related argument with the 5th argument of Modal_Force_Ext subroutine. |
|
MKID |
int [2] |
An array of integer type. Each value should be zero or a marker id. 1st value is defined as base marker. 2nd 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 postion 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. |
|
Pos |
double [12] |
An array of double precision type. The array size must be 12. First 3 values mean a position vector. The last 9 values mean an orientation matrix. |
|
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. |
