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

• 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

• Example 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 - For Dynamic Projects

• Startup actions for the dynamic project

• Example overall mass balance at the end of project solve
