Rocky comes preset with default values that you can use right away without modification if you choose. However, the minimum requirements for processing a simulation include setting up each of the following items:
One Particle set. (See also About Adding and Editing Particle Sets.)
One Input. (See also About Adding and Editing Particle Inputs.) Note: If the input is a Continuous Injection type, then one inlet is also required. The inlet can either be from a default feed conveyor or from a separate inlet geometry that you have added into the simulation.
Tip: To see a walk-through example of setting up, processing, and analyzing a simple simulation, review Tutorial - Transfer Chute in the Rocky Tutorial Guide.
