We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Saeed, 

this "Output Frequencies | Simulation" (in CFD-DEM coupled simulations) or "Time Interval" (in DEM-only) is about the outputs you wanna save (to visualize or access data, for example).   

To process the simulations, Rocky automatically calculates the time step, that you can see in Solver | Summary tab. You can also manually define a time step by enabling advanced features (from Rocky Menu | Options | Preferences |  Additional Features) and defining a Fixed Timestep in Solver | Advanced tab.

 

Best regards,

Lucas
