modelica - cd command doesn't work in Dymola.mos file

Question

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?

Answer 1

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:dymolastartup.mos

• Create a shortcut to Dymola.exe, (for Dymola 2021x: C:Program FilesDymola 2021xin64Dymola.exe)

• Add the .mos script as argument in the Target field in the properties of the shortcut. The result will be: "C:Program FilesDymola 2021xin64Dymola.exe" "C:dymolastartup.mos"
