The app builds on MOOSE (Multiphysics Object-Oriented Simulation Environment), with physics considering:

• Hydraulic Fracturing

• Proppant Transport

• Pulsed Power Fracturing

• Joule Heating

The package enhances the multiphase DualPhysics with particulate material constitutive models to simulate granular flow physics. The enhancement includes:

• Hypoplastic model

• Particle-particle interpolation-based non-slip boundary condition

• Particle-surface frictional boundary condition

• GPU accelerated simulation

• Open source is coming!

The software is a list of User MATerial subroutines (VUMAT) of Abaqus/Explicit for modeling granular flow physics. It includes:

• Density dependent Mohr-Coulomb model,

• Density dependent Drager-Prager\Cap model,

• Gudehus-Bauer hypoplastic model,

• Critical state-based NorSand model.
