Multiple bodies are fully supported in Creo Simulation Live. You can create multiple bodies in one part and use the bodies in Creo Simulation Live for your simulation needs. You can design and optimize cavity geometry independently in the context of the design, making it easier to visualize and use. You can easily move bodies and define positional states of bodies with family tables or simplified representations, using the Move feature.

You can create multiple bodies for the fluid cavity and also create solid geometry bodies. Use the concept of the construction body to exclude bodies representing cavities from the part geometry. You can also directly select bodies representing cavities as a fluid domain for a computational fluid dynamics (CFD) simulation.

Using multibody design you can design and optimize cavity geometry in a more efficient, flexible, and easier way, by designating it as a separate body while in the context of the entire part. This saves you time by simplifying exploration inside a part model instead of creating separate parts for an assembly.
