The following functions use a variable that the solver modifies during a simulation.
Frequency dependent function which evaluates an expression using the _FREQ variable at solve time. The solver will set _FREQ during the simulation.
An expression surrounded by single or double quotes that uses the _FREQ variable.
Result of evaluating the expression using the current _FREQ variable value.
See “Frequency Dependent Materials” for more information. The expression
syntax for the
freq_dep function differs slightly from the expressions
used in other areas.
