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 .
