3.1.80                            View | Show User Units

 

Description:

-         Switches between the standard unit and user unit modes

-         The units for each entity are defined in Element Settings Dialog Box

-         If this menu item is unchecked then you are in the standard (absolute) unit mode. In this mode the values of all entities are expressed in the standard (absolute) unit. This view allows for better understanding of the mathematical Petri net model and its processes, since the simulation is done in this absolute units.

-         If this menu item is checked then you are in the user unit mode. In this mode the entity value is expressed in the selected unit along with and displayed along with unit name in the lower-right corner. This view allows for better understanding of the physical model, since the entity values are given in user specified units.

 

Note: The simulation engine supports non-standard units, however it performs the calculation in standard units. The value of each entity expressed in standard units is the absolute value that is used by in the Petri Net model. This has the following consequences:

-         Process speed should be always defined in standard units

-         Entities representing two different physical properties, e.g. mass and volume can be connected by a process or used in one mathematical formula (script). The process or formula will operates on the absolute entity values expressed in standard units of each physical property.

-         Non-standard units are converted to standard ones during initialization of the entity value, e.g. during the file open operation.
