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. | |||||||||
Innvarn2 |
double [3*3] |
An array of double precision type. The array size must be 3. This argument is the invariant variable N1 of a selected RFlex body. Invariant variable N2 : Where, is a lumped mass on the node and is a translational mode shape vector (3x1) 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.
| |||||||||
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. |
