The following table includes the mode summary for both the conceptual and extended simulation to illustrate their differences. We use Fluid Flow mode only as an intermediate step for moving the extended simulation from Process mode to Dynamics mode. Therefore, we do not include it in the mode summary.
|
Process (Conceptual) |
Process (Extended) |
Dynamics (Extended) |
