Getting ready to use Cormas (v. 2016.11)



This is the new official version of Cormas. We continue to design the framework towards two directions: 1) to enable the development of interactive simulations, and 2) to facilitate the collective design and implementation of models.

Compared to the version of 2013, this new version focuses more on the first point: to interact more easily with the agents of a simulation in order to participate, alone or with others, in the execution of a scenario. This version is particularly suitable for:

  • Distributing a simulation on several machines (currently only on Windows OS), and monitoring the evolution of a remote simulation, displaying particular points of view and remotely manipulating the entities,
  • Stepping back in time of a simulation or replaying forward a previously stored simulation,
  • Creating an .exe file in order to instal and run a model on another machine (Windows),
  • Designing the agents' figures more easily thanks to the improvement of the drawing tool.

The main interface of Cormas

You can install by two ways: a simple and reduced installation, or a full installation of VisualWorks and Cormas:

Simple Installation (only for Windows)

The following file is for a minimal installation of VisualWorks and Cormas. Download (20 Mo) and unzip it on the folder of your choice. Then launch cormas.exe.

Full installation of VW and Cormas

1. Install VW7.6nc

Cormas has been developped for the 7.6 non-commercial version of VisualWorks® (Cincom Systems). VW must be installed on your computer. As the 7.6 version of VW is not anymore available on Cincom web site, and on the condition that you agree not to use Cormas for commercial purposes, you can directly download vw7.6nc (version for Windows and for Mac os X) from Cormas site. It is recommended to unzip the archive directly under the root of your hard drive to minimize configuration problems that may arise with recalcitrant OS.

2. Install Cormas (VERSION : Cormas v.2016.10.21)

2a. Install Cormas for the first time

Download the latest version of Cormas (, 20 MB) of November 2016. Unzip this Cormas folder into the directory VW7.6nc. The subdirectory 'cormas' is created. It already contains the file (instructions are detailed here). Copy your models in the subdirectory VW7.6nc/cormas/Models/.

(Keep your old version of Cormas. If an older version of Cormas is already installed on your computer, you can keep this version. Just change the directory name 'cormas' to 'cormas_Old' or whatever.)
or 2b. Update your Cormas previous version

If Cormas is already installed, do a simple update by unzipping the (2 MB) in VW7.6nc/cormas/ directory (erasing the previous cormas files). Open and select the menu: '?' and 'Update Cormas'.

or 2.c Alternative installation: from Store
When VisualWorks is installed, download Cormas from the "Public Repository" of Store. From the VW main window, connect to Store (Menu -> Store -> Connect to Repository...), then select  "Cincom Public Repository" and Connect. Thus, from Menu -> Store -> Published items, look for cormas and load it.

Troubleshouting for Windows 7

Sometimes on Windows 7, the VisualWorks Home directory cannot be changed. See the procedure to fix that.

Previous versions

The previous versions of Cormas are also available.
