Number of Cases and Performance

The number of cases in a Case Study depends on the number of steps that you define for your manipulated variables and parameters. If you have more than one manipulated variable or parameter, the growth in the number of cases is multiplicative:

where

nm is the number of manipulated variables or parameters

ns,i is the number of steps associated with the manipulation of variable or parameter i

nt is the total number of cases

Currently, nm must be less than or equal to 2.

When you run a Case Study, the software re-solves the simulation for each case. Currently, the software solves the entire simulation, and there is no way to isolate a portion of the simulation to limit the solve. If you use too many steps or your simulation is very large, the Case Study may take a considerable amount of time to run.
