Felino: Extension of an open-source phase-field framework to geomaterial fracture

This work presents an extended version of Felino (Chou & Darabi, 2025), an open-source phase-field fracture framework.Felino is implemented as an application built on top of the MOOSE finite-element framework (Permann et al., 2020), which uses libMesh as its underlying numerical library (Kirk et al., 2006).The extension introduces constitutive models for geomaterials, enabling simulations where tensile and compressive strengths differ.
