Modeling fractures that pre-exist or initiate and propagate in a porous media is essential in many engineering and scientific applications. These fractures are characterized by the interaction between the pore fluid and volumetric elastic and inelastic deformation of solid skeleton. These coupled processes are complicated to model because of the complex interactions between solid, fluid and fracture. This session invites contributions to computational techniques for modeling fracture in porous media, including but not limited to:

• modeling of pre-existing fracture, initiation and propagation of new fractures
• poro-mechanical coupling schemes 
• advanced remeshing algorithms
• continuum fracture models 
• discrete fracture-matrix (DFM) models
• phase field methods
• peridynamics
• extended finite element methods
