Description
ifbody
int
Sequential id of RFlex body defined in RecurDyn/Solver. This is a related argument with the 5th argument of MODAL_FORCE subroutine.
modeid
int
Selected mode sequential id. The user can get the selected mode sequential id using the Get_rflex_modeid auxiliary function.
Innvarn3
double
[3*3]
An array of double precision type. The array size must be 9. This argument is the invariant variable N3 of a selected RFlex body.
Invariant variable N3 : 
Where, 
is a lumped mass
on the 
node and 
is a translational mode
shape vector (3x3) of 
node and 
mode. 
is a number of selected
modes. 
is an initial position
vector of node with respect to the
reference frame of RFlex body.
Index of 3x3 matrix result is defined as follows.
