One major feature in IntelliSuite v8.5 is the capability to simulate advanced fluid-structure interaction. And unlike other tools that can only handle rigid body simulations, IntelliSuite fully supports interactions with deformable, non-rigid bodies. Full coupling with the PiezoMEMS module makes it easy to analyze devices such as a piezoelectrically-actuated micropump, shown below.
