MotionSolve supports DSA only for Kinematic, Static, and Quasi-static
analyses
At this time, DSA for Dynamic analysis is only supported via finite differencing,
dsa=”FD” and dsa=” FD_SERIAL”.
DSA for Linear analyses is not supported.
Note: To compute the sensitivities, MotionSolve requires the design
variables, how the model is parameterized with these design variables, and what
the response variables are. DSA yields correct answers only when the model is
designable. For non-designable models, it returns ZERO as the answer.
