Defining an Expression

Expressions are mathematical descriptions that typically contain intrinsic functions, such as sin(x), and arithmetic operators, such as +, -, *, and /, as well as defined variables. Expressions may also contain pre-defined constants, but such constants may not be reassigned a new value. Defining one variable in terms of another makes a dependent variable. Dependent variables, though useful in many situations, cannot be the subject of optimization, sensitivity analysis, tuning, or statistical analysis.

Numerical values may be entered in Ansys Electromagnetics’ shorthand for scientific notation. For example, 5x10⁷ could be entered as 5e7.
