cd command doesn't work in Dymola.mos file

I am trying to configure dymola.mos file, here is an example of changing directory, but when I activate Dymola, it seems the working directory doesn't change at all, even though the log shows Dymola run the script.
My question is:
How could I make the cd command work in the dymola.mos file?

Solution

  • I assume you have activated the option Save startup directory. You can check this with the flag Advanced.StartupDirectory, which will be either 1 or 2. You can simply turn that off or follow the steps below.

    From your command log we see that:

    1. Dymola first executes the script <install-path/insert/dymola.mos
    2. Then it restores the settings stored in setup.dymx

    Hence the settings in setup.dymx override your working directory.

    Instead of using <install-path/insert/dymola.mos you should use a custom .mos script, which is passed as first argument to dymola.exe on startup. This will always be executed last.

    Example for Windows

    • Create the file startup.mos somewhere, e.g. in C:\dymola\startup.mos

    • Create a shortcut to Dymola.exe, (for Dymola 2021x: C:\Program Files\Dymola 2021x\bin64\Dymola.exe)

    • Add the .mos script as argument in the Target field in the properties of the shortcut. The result will be: "C:\Program Files\Dymola 2021x\bin64\Dymola.exe" "C:\dymola\startup.mos"
