Hello,

A colleague of mine is using a Xcos model that will only run under Scilab 5.5.2.  
He and I tried to run it under Scilab 2024 without sucess.  
We are really rookie here.

Can you help find what needs to be adjusted?

Hello,

Currently SIMM is not available in Scilab 2024. If you are interested to contribute, feel free to push PR to [scilab / forge / simm · GitLab](https://gitlab.com/scilab/forge/simm).

Thanks,

Clément

Unfortunately, that’s is not something we are capable of.

Would the alternative be to rebuilt the model using “Coselica” TB?

In fact SIMM installs fine in Scilab 2024.0.0 (by on-the-fly compilation) **but you have to install coselica before** , as the dependency of SIMM upon coselica does not seem to be set in the metadata of the package.

However, after satisfying this, there is a problem when SIMM loads:

```auto
atomsLoad : Une erreur est survenue au cours du chargement de 'SIMM-0.6.2':
	exec: error on line #172: "Variable non définie : cos_utils_lib"

```

Hi all,

Coselica & SIMM have been updated to be compatible with Scilab 2025.0.0.

Best regards.
