CODE_BRIGHT is a Finite Element Method (FEM) program capable of performing coupled thermo-hydro-mechanical (THM) analysis in geological media. It has been developed at the Department of Geotechnical Engineering and Geo-Sciences of the Polytechnic University of Catalonia (UPC), and works combined with the pre/post-processor GiD, developed by the International Center for Numerical Methods in Engineering (CIMNE).

The Code_Bright project is funded by a Consortium composed by SKB (Sweden), Posiva (Finland), GRS (Germany) and ANDRA (France). The members of the steering commitee of this consortium are Anders Sjöland (Chairman, SKB), Mika Niskanen (Posiva), Oliver Czaikowski (GRS) and Antoine Pasteau (ANDRA).



Installation of Code_Bright requires installation of GiD pre-post processor.
STEP 1) Installation of GID version:

Install last GiD official version: Go to http://gid.cimne.upc.es for downloading and registration options of GiD software. Note that there is an option for one month free registration.

STEP 2) Installation of the CODE_BRIGHT version:

Go to the downloads section and download the code_bright zip file with the program. After unzipping, copy the folder Code_bright_vn.gid into the folder /PROBLEMTYPES within the main folder of GiD (This subdirectory is by default C:\Program Files\GiD\GiDversion#\problemtypes for Windows english version and GiDversion# except if another destination folder was specified for GiD program during its installation).
