How can I set a initial value for input parameters in FMU?

I want to co-simulate the FMU in PowerFactory and want to assign initial value for the parameters, how can I do it while creating an FMU.

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" />

I saved my file as FMu export format using matlab 2020b in built save as function, oit generated only .fmu file but no xml file. did save as fmu export option geretares fmu and xml or only .fmu file?. please let me know

You have to unzip the .fmu file to see the ModelDescription.xml.

@Satwik is there a way to set the initial values of variables in <ModelVariable><start> attribute when exporting the FMU with FMI version 3.0? Changing the ModelDescription.xml after exporting it as Standalone FMU seems not to be the best practice to me.
