Function Elements

GoldSim Quick Tour (3 of 23)

Other elements in GoldSim represent functions. Function elements compute outputs based on defined inputs. That is, they require one or more inputs, carry out a specified calculation on those inputs, and produce one or more outputs. GoldSim provides a wide variety of function elements. The simplest and most general function element is an Expression.

Expressions produce a single output by calculating user-specified formulas, such as 2 + 3, A*B, or sqrt(55). Similar to a cell in a spreadsheet, when defining an Expression, you can use a wide variety of mathematical operators and functions. You can even use conditional operators (e.g., >,<, =) and “if, then” logic to define Expressions.

Example Expressions

Other function elements have predefined functionality. For example, a Selector provides an easy way to create nested if,then logic.
