Software for THM analysis of bentonite engineered barriers

Results of the research project "Numerical modelling and laboraory characterisation of bentonite barrier in radioactive waste repositories in Czech Republic" suported by the Technology Agency of the Czech Republic.

This page is devoted to a module of SIFEL code - an open source finite element (FE) computer code designed to Thermo-hygro-mechanical analyses of bentonite materials used in engineered bariers for nuclear waste storage. This software was developed in the scope of the project No. TK01010063 suported by the Technology Agency of the Czech Republic.

Hygro-mechanical analysis of bentonite material - Mockup tests

Hygro-mechanical analyses of bentonite materials consist of three numerical simulations of watering of bentonite with three different dry densities (1298, 1498, and 1743) in a unique device measuring swelling pressures.

Hot to run computations in Linux:
Download source files from this link Version of THM Model. Then unpack. In the directory METR, build binary files by "make". The binary file is located in the directory "../BIN/METR/SRC/_DBG". In case of compilation with optimization "make opt", the binary file is located in "../BIN/METR/SRC/_OPT". Download input files and unpack into directory METR. Copy the binary file into this directory. To run the computer simulation for dry density 1298 type "./metr bentonite_experiment_metr1_1298.in". To run the computer simulation for dry density 1498 type "./metr bentonite_experiment_metr1_1498.in". To run the computer simulation for dry density 1743 type "./metr bentonite_experiment_metr1_1743.in".
