Once you have run your simulation, you may want to change out geometries or reset certain values before running the simulation again. In Rocky, there are three main ways to do this:
Create a Copy for Restart: In this scenario, you would first select (from the Time toolbar) which timestep you want to use as the starting point for your copy, then you would Save a Copy of a Partially Processed Simulation for Restart Purposes at that point. Within the new copy-whose time has been reset to "0" seconds but whose original results are still visible-you would then change out only certain setup parameters such as geometry files or particle sets (see also About Changing Geometries and/or Particles in a Partially Processed Simulation), and then restart processing within the copy. This is useful when you want to keep the beginning results of your original simulation, but want to change some of the parameters for the latter portion of processing.
Save a Copy of the Setup: In this scenario, you would Save a Copy of Only the Simulation Settings; Not the Simulation Results, change out any setup parameters you like in the new copy, and then process the new copy. This is useful when you want to keep the results of your simulation but want to reuse the setup parameters in a different but similar project.
Delete Your Simulation Results: In this scenario, you would first Delete the Results of a Simulation (But Keep the Setup), change out any setup parameters you like, and then start processing the project from the beginning. This is useful when you know you do not want to keep your simulation results but do want to reuse the setup parameters in your next analysis.
In both the latter options, you are able to Set Your Simulation Parameters as usual prior to running your simulation again. In only the first option are you limited in what setup parameters you can change.
