The following issues are checked with this test model:
Support for String parameters, so it is possible to set a parameter of type String
for an FMU instance. In the test model, a file name must be defined.
Support for reading data from a file. The difficult part is that the file to be read
must be identified when exporting the FMU and this file has to be stored inside the
FMU, and when importing the FMU, this file has to be read during importing
or during initialization.
