Description

This command is used to define default values to parameters inside a scope (see example below). The default value is overwritten by any prior defined value.

The range ID (rid) refers to either one of the commands PARAMETER_RANGE_CONTINUOUS, PARAMETER_RANGE_DISCRETE or PARAMETER_RANGE_BOOL.

Defining a physical quantity (quantity) is optional. It helps IMPETUS Solver determine how to convert parameters between different unit systems.

Example

Default parameter values

In the COMPONENT_BOX command %a=20 has its default value, while %b=100 has its previously defined value.

*PARAMETER %b = 100 *PARAMETER_DEFAULT %a = 20 %b = 40 # # Here %a=20 and %b=100 *COMPONENT_BOX 1, 1, 10, 10, 10 0, 0, 0, [%a], [%b], 20
