Description
PyLith is an open-source finite-element code for dynamic and
quasi-static simulations of crustal deformation, primarily earthquakes
and volcanoes.
Features
- Quasi-static (implicit) and dynamic (explicit) time-stepping
- Cell types include triangles, quadrilaterals, hexahedra, and tetrahedra
- Linear elastic, linear and generalized Maxwell viscoelastic, power-law viscoelastic, and Drucker-Prager elastoplastic materials
- Infinitesimal and small strain elasticity formulations
- Fault interfaces using cohesive cells
- Prescribed slip with multiple, potentially overlapping earthquake ruptures and aseismic creep
- 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
- Templates for adding your own bulk rheologies, fault constitutive models, and interfacing with a custom seismic velocity model.
- User-friendly computation of static 3-D Green's functions
