Attachment
Type
For Attachment variables, you can specify the attachment
type as one of the following:
• Stream. Generic specification, implying that the
stream can be either material or energy.
• Material Stream. The attachment is a material
stream and cannot be an energy stream.
• Energy Stream. The attachment is an energy stream
and cannot be a material stream.
Flow
Direction
The choice for Flow Direction impacts the PFD in its
presentation of nozzles for unit operations in Attach Mode.
For Attachment variables, you can specify the flow direction
as one of the following:
• Unknown. The PFD does not know until run-time if
the attachment is a feed or product; depends if the
attachment is already attached to something.
• Feed. Only feed nozzles are presented by the PFD.
• Product. Only product nozzles are presented by the
PFD.
Numeric
Type
For variables of type Real Number, a unit type can be
specified. This guarantees that the appropriate value
appears by the property view according to the user
specified unit set.
N
Dimensions
For all variable types except Message, the variable
dimensions can be specified as one of the following:
• None. Single value.
• Vector. One dimensional array.
• Matrix. Two dimensional array.
• Cube. Three dimensional array.
Only the Real Number variable type has access to all
dimension types. The other variable types have access to
only None and Vector.
