PGM Files using Class and Functions

Using Array and Matrix

• Table lookup using Array and Matrix
• Set A Table of Values Using Matrix Class
• Solving a tridiagonal system of equations

Quick Mass balance using Predefined Class: TagSelect

• Example overall mass balance at the end of project solve

• Example species mass balance at the end of project solve

• Example elemental mass balance at the end of project solve

Species Check - Generate Species Lists based on "With Flow" and "No Flow"

The following PGM examples can be used to check species at the end of project solve,
NOTE that in Build139 or later, user can get the used/unused species list directly from Plant Model - Species tab.

• How to generate a list of Species with Flow, useful for stream table reports
• How to check if a species is not used in the project (has no flow anywhere)
• How to compare two lists of string variables

User Defined Class and Functions

Class and Function/Subroutine can be written as part of the main PGM file OR separately in its own file. If the Class or function/subroutine can be used by multiple PGM or projects, it is best to store the code in a separate file, so it can be re-used easily. Please see Sharing Classes between Projects for more information.

In the following examples, the Class definition is stored in a separate pgm file, the class pgm file is inserted using the include file syntax when it is required.

• Example Class to Set Species Splits
• PGM Example - PGM Class to calculate the Agitator Power required in a Vessel
• Example Class to Find a user specified Reaction in a Reaction Block

In the following examples, the Class is written as part of the PGM code. User may copy the class definition into its own file if required.

• Example Class to set Aqueous Feeder based on concentration
• Example Class to set Evaporation based on user defined correlation
• Example Class to calculate Alumina properties
• Example Class - Check Elemental Balance of a Process Unit Operation
• Example : using Enum Drop list and Drop List in a class
• Example Class to assist with solving sensitive PID control loops

Example - For Dynamic Projects

• Startup actions for the dynamic project
• Example overall mass balance at the end of project solve
