Follow-up from a previous topic: > [@Convert a XCOS model from Scilab 5.5.2 to Scilab 2024](https://scilab.discourse.group/t/convert-a-xcos-model-from-scilab-5-5-2-to-scilab-2024/327/4): > > 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: 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" S. The tollbox SIMM needs to be updated to work with the newer versions of Xcos and Coselica. While this may happen, we think our problem can be solved with only Xcos/Coselica. We need help/training on how to do that. The goal is to model a DC motor acting on a mechanism. Input (example): Voltage PWM command, current sensing. Output: rotation angle on the mechanism. Torque is dependant of position (angle) If you know anyone who could help Please let us know ---

Hello, I got the same problem on SCILAB 2024.1.0 COSELICA is installed correctly. Schematics can be created in XCOS. However, SIMM creates problems. It’s pretty annoying, all this talk of incompatible modules. DASSAULT SYSTEM, which took over the lead of SCILAB, should also have taken over the lead of the most widely used modules, namely : - CPGE, COSELICA, SIMM at the very least. As a result, I’m still using my SCILAB 5.5.2 version, which works perfectly with all these modules. It’s a real shame. Translated with [DeepL.com](http://DeepL.com) (free version) ---

Hello @Pascal77 , Thanks for your feedback about Scilab (and particularly your post about [uiimport](https://scilab.discourse.group/t/demonstration-of-the-new-uiimport-instruction-scilab-2024-1-0/527)). We just updated the SIMM toolbox on ATOMS, this module should now work with Scilab 2024.0.0 (and recent 2024.1.0 version). As @mottelet said, the situation is quite complicated for many ATOMS modules as the successive maintainers sometimes only posted binary versions on ATOMS (and did not contribute to the source code on Scilab forge for example) hence creating a difference between the available binaries and sources. Once in this situation, updating the toolbox is complicated and time consuming. Development team is only composed of a few people and maintaining Scilab in already a huge work so we do not have lot of time for ATOMS toolboxes but we do our best. This is why contributions are welcomed from the users community and now Scilab (and most ATOMS toolboxes) source are available on Gitlab, contributing is very much easier. Thanks again for using Scilab. Vincent ---

Hello Vincent, thank you very much for your message. I’m well aware of the workload involved. I must say that it’s already a great satisfaction to see that SCILAB has been (re)taken in hand by competent and motivated people. The successive changes that have taken place in close succession are testimony to this. For my part, I’m not a developer, just a user, otherwise I’d have loved to be part of this renaissance. And finally, how can I go about testing the new SIMM on the latest version of SCILAB? Have a nice evening. Best regards, Pascal Translated with [DeepL.com](http://DeepL.com) (free version) ---

I am trying the new version of SIMM in SCILAb 2024.1.0 Installation was fine. No encountered problems. My first try is very simple : ![essai SIMM 0.6.2.2 - Xcos diagram](https://global.discourse-cdn.com/free1/uploads/utc/original/1X/9da00d55876621ad0f9f1cdf2e6cdaaaa7f61ac2.png) All blocks come from SIMM palette. We can see a problem regarding REP\_TIME block. Then I lauch the simulation, and I have an error message 🙂 ![essai SIMM 0.6.2.2 - error message](https://global.discourse-cdn.com/free1/uploads/utc/original/1X/3f5743b0a450a9bb7b04587b77c915877dce1a2f.png) When I click on OK button, I have errors messages in the console. ```auto ATTENTION : Le diagramme contient des blocs implicites, compilation en cours pour le solveur implicite. "SIMM post" "Erreur dans post_xcos_simulate : Simulation interrompue." ``` So, it seems I get the same kind of errors than QwillDune. Remark : As I am french, my SCILAB version is in french. Sorry for french texts in this post. ---

I just wanted to share a comment about file names regarding old SCILAB versions (for example in 6.1.1 version). Indeed, files names are very important with COSELICA and SIMM pallettes. _Avoid accentuated characters and spaces in file names._ Otherwise, an error is generated and the simulation stops : ![2024-06-11 20_40_03-Message d'erreur avec caract. accuentué Console Scilab 6.1.1](https://global.discourse-cdn.com/free1/uploads/utc/original/1X/cfe0b473dc7f72e600964f964b4c01a1dba04bb8.png) Once the name is correct, it’s possible to simulate a diagram (with a few restrictions). Here’s an example: ![2024-06-11 20_44_29-RLC_série_SIMM (C__Users_Pascal_Documents_SciLab files_SCILAB from 2024 version_](https://global.discourse-cdn.com/free1/uploads/utc/original/1X/15ed075e14dca021758bfd9b89f685ca1241e5ce.png) The working plots are given below: ![2024-06-11 21_07_02-RLC_serie_SIMM_1](https://global.discourse-cdn.com/free1/uploads/utc/original/1X/ded4b38ed68616fbf5b4f90e7c1d3a8f3bbf3330.png) ![2024-06-11 21_07_02-RLC_serie_SIMM_2](https://global.discourse-cdn.com/free1/uploads/utc/original/1X/537776b68d811a615a2e45da5cb87b099fa97b4e.png) ---

Hello Stéphane, Thank you for your link. Finally, the installation of **vcredist\_x86.exe** solved the problem. No need to do other things. The simulation is working fine. Moreover, the block named TIME is working fine too. So it is possible to mix simulations with TIME and with the clock block. I have not yet tested PARAM\_VAR. Do you know if CPGE will be restored for working with SCILAB 2025? Best regards Pascal ---
