The following table includes the mode summary for both the conceptual and detailed engineering simulations to illustrate their differences. We use Fluid Flow mode only as an intermediate step for moving the detailed solution from Process mode to Dynamics mode. Therefore, we do not include it in the mode summary. You can find additional details about each mode in the following sections.
