How can I change the build folder of a model?

I can use the fuction rtw.getBuildDir(..) to see the build information of the model. But is there a way to set/change these information? e.g. rtw.setBuildDir? Especially i want change the 'BuildDirectory' and the name of the Folder.

You can do this using the Simulink preferences or the Simulink.fileGenControl function. Take a look at this blog:

Thanks a lot Sebastian

but I want to change the BuildDirectory. For instance "MyMode_ert_rtw" to "AnotherModelName" and not the CacheFolder or CodeGenFolder. Any ideas?

Simulink.fileGenControl has a nice help-file to do exactly what you wanted.

You need to first get the current configuration:

cfg = Simulink.fileGenControl('getConfig');

Then edit the data structure inside cfg to point to where you want the new build to be located at

For example:

cfg.CodeGenFolder = fullfile(pwd, '\SomeNewDirectory');

Then you'll need to set it using 'setConfig'

Simulink.fileGenControl('setConfig', 'config', cfg);

This worked for me to control where the build folders and cache folders need to go to.

EDIT: Doesn't look like you can actually change the folder name. What you could do I suppose is create a Directory name of your choosing and set that as where all of the simulink artifacts go.

I wanted to remove suffix (_grt_rtw).

Proceeded with following steps:

1. Created custom .tlc file within my project -> copied existing one (C:\LegacyApp\Matlab2024a\rtw\c\grt\grt.tlc) into project repository, and renamed it (grt_custom.tlc).
2. Added location of the new .tlc file to the MATLAB project path, so that it can be found.
3. Updated model configuration, choosen the new one (grt_custom.tlc). If it is not visible as an option, it could be that file location is not within MATLAB path.
4. Some configuration entries were changed, so I reverted them back.
5. Uncommented line (it was commented out within the whole block): rtwgensettings.BuildDirSuffix = '_grt_rtw';
6. In order to remove suffix, changed this line to: rtwgensettings.BuildDirSuffix = '';
