DADS/Linear

DADS/Linear automatically extracts linear information from non-linear DADS models. Results include coefficient (A and B) matrices, and an eigenvalue calculation to evaluate linear model modes and frequencies for stability. DADS/Linearization allows selection of independent generalized coordinates for use as linear model states with automatic determination of the independence of the selected coordinates, and results may also be reported at each analysis time step. The motion associated with linear system frequencies is reviewed through eigenvector animation. The results are exported for use with external controls and mathematical analysis programs. Results from these programs can be returned to the non-linear DADS model.
