Damage mechanics has often been used to study the mechanical behaviour of concrete structures. Damage models can be used to simulate the quasi-brittle behaviour of cementitious materials, since they are capable of representing cracking under various loading conditions. In this post, we present the i... Read more...
In this post, Marek Pękala describes a recent application of Comsol at Amphos 21 to study the saturation with water of spent nuclear fuel. This work was financed by a 7FP project of the European Commission to study fast/instant release of safety relevant radionuclides from spent nuclear fuel. Com... Read more...
A large-scale, long-term simulation of the hydrogeochemical behaviour of fractured rocks is shown in this post. The simulations are performed with iCP, the COMSOL-Phreeqc interface, that allows performing 3D reactive transport simulations in discrete fractures accounting for matrix diffusion (as a 4...

Dating groundwater is something that hydrogeologists like to do for different practical purposes. Conceptual modeling of aquifers, evaluating the sustainability of groundwater exploitation in arid and semi-arid areas, sitting a deep geological repository for radioactive waste are obvious examples...

In this post, Jordi Font, Senior Consultant and Project Manager at Amphos 21, blogs about a program (developed at AMPHOS 21), that calculates water inflows during excavation of underground galleries. The program, denoted as TunFlow, is based in the analitycal solution published by Perrochet and D... Read more...
