The Parameters element is a location for evaluated, user defined variables that can be used in other elements of the simulation. A parameter is a mathematical combination of constants and other parameters. You may add a new parameter using the Add button under the Elements Tree.
These variables may be assigned where appropriate by right clicking the value and selecting Assign Parameter.
kind (not editable): The kind of constant; a User Defined kind.
description: A descriptive name of the parameter.
expression: This is the user-supplied expression that will be calculated to determine the value of the parameter. It can include any pre-defined Constants as well as real numbers and some functions. Use a “^” to raise numbers to a power. Available functions include:
- abs(x): takes the absolute value of “x”.
- rint(x): rounds “x” to an integer.
- sqrt(x): take the square root of “x”.
- sin(x): take the sine of “x”, where “x” is in radians.
- cos(x): take the cosine of “x”, where “x” is in radians.
- tan(x): take the tangent of “x”, where “x” is in radians.
- asin(x): take the arcsine of “x”, where “x” is in radians.
- acos(x): take the arccosine of “x”, where “x” is in radians.
- atan(x): take the arctangent of “x”, where “x” is in radians.
- sinh(x): take the hyperbolic sine of “x”, where “x” is in radians.
- cosh(x): take the hyperbolic cosine of “x”, where “x” is in radians.
- tanh(x): take the hyperbolic tangent of “x”, where “x” is in radians.
- log(x): take the natural log of “x”.
- log10(x): take the base 10 log of “x”.
- exp(x): raise Euler’s constant to the power “x”.
value: The RSim calculated value of the expression.
