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. |
innvarn1 |
double [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 N1 : 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. |
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. |
