FRACSIMA is a software development company working specially on numerical modeling tools for highly non-linear materials. Fracsima softwares aim for the analysis and simulation of coupled Thermo-Hydro-Mechanical phenomena specially in multi-fractured materials. Their field of applications covers tunnels and geotechnical prjects in rock formations, mining and oil & gas manufacturing problems, as well as the analysis of fracture propagation in metal alloys, polymers and composites.

DISROC is a general purpose Finite Element code for modelling mechanical deformation and thermal and hydraulic diffusion phenomena in materials. It is specially conceived for media containing discontinuities like fractures, cracks, rockjoints and masonry joints, as well as linear reinforcements like rockbolts and fibers in concrete and composite materials.

Disroc includes a large variety of non-linear constitutive laws (see Materials) and allows taking into account thermal stresses and fluid pressure effects.
