Aifrac
_______
The AiFrac is a software for modelling the three-dimensional fracturing with advanced numerical algorithm.By linking with TOUGH2 (https://tough.lbl.gov/) , the TOUGH-AiFrac simulator is developed to simulate three dimensional fracturing with Hydraulic-Mechanical-Thermal (H-M-T) coupling process. The TOUGH-AiFrac simulator has been successfully used to investigate the propagation of hydraulic fractures in petroleum engineering, mining engineering, and thermal exploitation.
DynaETM
_______
The DynaETM is developed to model the dynamics of multi-bodies with fragmentation using the Energy Tracking Method (ETM). In DynaETM, the ETM is used to resolve collisions between multiple non-convex bodies in three dimensions. In the advanced algorithm of ETM, impulses are applied g radually at multi-point contacts, and energy changes at the contact points are tracked to ensure conservation.
