RACCOON: A versatile framework for variational approaches to fracture with coupled field phenomena

Variational approaches to fracture and their regularized counterparts have received great success modeling engineering problems incorporating a wide range of physical phenomena. There is considerable demand for a unified and flexible computational framework for phase-field fracture with coupled field phenomena. RACCOON aims to enable such development by providing modular interfaces for each individual physical component, so that implementing the coupling between different phenomena becomes an easy task. Such a modular framework, combined with other high-level features of RACCOON , enables rapid development of models for brittle/cohesive/ductile fracture in general nonhomogeneous, anisotropic, dissipative, porous media, optionally coupled with thermal effects, dynamic effects, viscous effects, and etc. In addition, RACCOON is developed within the MOOSE framework, which enables a wide range of capabilities including, but not limited to, dimension-independent programming, automatic differentiation, scaling to a large number of processors, and mesh adaptivity.
