When you create an FMU (Functional Mock-up Unit), you can define parameters with initial values in the FMU description file (modelDescription.xml). This file includes metadata about the FMU, such as the name of the model, the type of solver used, and the number and types of inputs and outputs.
Here's an example of how you can define a parameter with an initial value in the FMU xml description file:
ScalarVariable
name="myParameter"
valueReference="1"
variability="parameter"
initial="1.0"
