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.
