This is using an overset mesh to model the motion of the blades.

We also look at a demo example we put together using rubber balls that are turning around and being mixed in a rhythm mixer. The particles can be part of reacting flow if you're doing combustion, either a liquid fuel or solid fuel, but with LMP models, it will calculate the particle path, and that path will be saved and you can go back and plot what the particle path was for your analysis. It has many uses, it can be done for steady state, it can be done for transient analysis. Usually this is done with sprays and droplets, so there are thousands or millions of particles injected, grouped into what is called parcels and tracked throughout the flow. With the Lagrangian Multi-Phase you're essentially injecting a number of particles into your simulation flow.

There are two main Lagrangian methods within STAR-CCM+, LMP (Lagrangian Multi-Phase) and DEM (Discreet Element Method). In this video we look at the Lagrangian method for multi-phase models. NX Open Customization & Automation Services.Simcenter Femap APIs - Automation Programs.
