Before starting an automatic simulation using a User database, the user can select which variables he wants to simulate. It can be done by selecting Simulation/Automatic simulation setup in the main menu.

STEP 1:

• In the Properties tab (see figure below), deselect the undesired properties in the check box column Sim. Still, these properties can be used as models' entries to estimate other variables (example: Ergun's constants E1 and E2 to predict pressure drop and liquid holdup for some models). If the information are not available in the user database, the user can choose a model to evaluate the missing parameters in the Default as input column. No default means that the corresponding property will not be estimated if used as input in some models.

STEP 2:

• In the Models tab, the user is presented to the full model listing used to simulate automatically the selected properties. Some of them can be deselected (not used) if desired.

STEP 3:

• Once the properties and models are selected, press OK to finish this procedure.
