Dymola mos script environment variables

问题

Is there a way to use the Windows environment variables in Dymolas .mos scripts?
Something like this:

// Load libraries, last one determines the working directory
openModel(%USERPROFILE% + "Documents/Dymola/MyTestLib/package.mo");

Alternatively, does Dymola know some other predefined pathes? I would like to make .mos script a bit more portable to a different PC.

You can use the getEnvironmentVariable function from the MSL.

So this should do what you want:

user_profile = Modelica.Utilities.System.getEnvironmentVariable("USERPROFILE", convertToSlash=true);
openModel(user_profile + "/Documents/Dymola/MyTestLib/package.mo");

On startup Dymola also defines two useful environment variables:

• DYMOLA: the dymola installation directory, e.g. C:/Program Files/Dymola 2019 FD01
• DYMOLAWORK: the startup directory, with C:/Users/<user>/Documents/Dymola as default. See user Manual 1 for details.
