Formatting Variable Definitions

Often the algebraic expressions formulated for rate-controlling or auxiliary variables can be quite long. When variables are defined in a ‘Variable Definitions’ dialogue box, Powersim Studio does not automatically wrap the text, with the consequence that long definitions may not be easily viewed. Unfortunately, long algebraic expressions that cannot be viewed in their totality can be difficult to debug. Parts of the expression which fit together logically may not be completely viewed a single screen. To help overcome this there are some simple formatting aids we might use when defining variables, including:

  • line breaks, and
  • indenting.

     The following is designed to explain how to improve formatting when defining variables in a ‘Variable Definitions’ dialogue box .
