UPC - Dept. of Civil and Environmental Engineering



CODE_BRIGHT is a general-purpose finite element program developed by the Department of Civil and Environmental Engineering of the Universitat Politécnica de Catalunya (DECA-UPC) for the analysis of coupled thermo-hydro-mechanical (THM) phenomena in geological media.

The development of CODE_BRIGHT started in 1990 with the purpose of modelling the response of saline materials in the context of deep nuclear waste disposal. The initial capabilities were soon extended to include a wider range of geological materials and, in particular, unsaturated soils. General transport processes and their interaction with the material mechanical behaviour were added in order to develop a generalised tool for THM analysis. CODE_BRIGHT has been extensively verified and validated in international benchmark exercises. It has been applied to the analysis of different geoenvironmental schemes and waste disposal designs. In the recent past many other relevant geotechnical problems involving saturated/ unsaturated flow and stress strain behaviour have been analysed with the help of CODE_BRIGHT. The course will provide an appropriate coverage of theoretical background, numerical aspects, details of problem solving and examples of application.

CODE_BRIGHT is backed by a detailed reference and Tutorial Manual, a description of the Theoretical Bases and a publication on Validation Exercises solved with the code. Course material includes the Theoretical Background and Validation documents as well as a copy of relevant publications.
