*SetFMUParameters()
Sets values for parameters of an FMU entity.
Syntax
*SetFMUParameters(varname, {“par_1_name; par_1_value`”, “par_2_name;`par_2_value`”,… “par_n_name;`par_n_value`”} )Arguments
- varname
- The variable name of the FMU entity.
- par_1_name, par_2_name,…par_n_name
- Names of the parameter in the parameter list of the FMU.
- par_1_value, par_2_value,…par_n_value
- Value to be assigned to the parameter.

Comments
Use the *FMU() statement to create a functional mock-up unit (FMU).
FMU parameters are variables that characterize the FMU system. Through parameters, FMU behavior can be varied. Parameters could be of any following datatypes – Real, Integer, Boolean, String, Enumeration
When FMU has parameters, they would have default values. Parameter values if not provided will take the default values as specified in the FMU.
Parameters could be of type real, integer, Boolean or string.
This statement assigns a value to a parameter. The name of the parameter is pre-defined in the FMU. The parameter values are provided as an array comprising of name;value pair separated by commas.
The array is defined within curly braces.
