- Spontaneous slip with slip-weakening friction and Dieterich rate- and state-friction fault constitutive models
- Time-dependent Dirichlet (displacement/velocity) boundary conditions
- Time-dependent Neumann (traction) boundary conditions
- Time-dependent point forces
- Absorbing boundary conditions
- Gravitational body forces
- VTK and HDF5/Xdmf output of solution, fault information, and state variables
