Release Notes: This version can read mesh files exported by the mesh generation programs CUBIT and EZ4U, and introduces kinematic fault sources, heterogeneous coefficients for anistropic media, absorbing boundaries with arbitrary orientation, and Gaussian source time function and pre-processing utilities to compute critical time steps. Bugs are fixed in time-weakening friction and handling of fault tip nodes of single-sided faults.
Release Notes: This version introduces the following features for dynamic faults: more stable curved elements for non-planar faults with smooth normal, cohesion in fault strength, more options in time-weakening fronts for rupture nucleation, enabled time-weakening in combination with rate-and-state-dependent friction, and easier setting of the fault zone viscosity layer. In addition, the flexibility of the Matlab mesh generation tools was enhanced.
Release Notes: This version introduces useful features for dynamic faults: smooth mesh generation for fault surfaces, instantaneous healing in slip-weakening friction, optional suppression of fault opening, easy tagging of near-fault elements, separate output of initial values, and cohesive normal response. Bugs in the plastic solver were fixed.
Release Notes: This version includes more capabilities for structured and semi-structured meshing, stress glut and seismic potency outputs for dynamic sources, and new mesh visualization and snapshot animation tools.
Release Notes: This version features new outputs (energies, curl, div, values at each fault side), new post-processing tools (response spectra, Arias intensity, significant duration, extract values on points and lines), and Brune's source time functions.
Release Notes: This version introduces a Maxwell-viscous regularization for plasticity and structured meshing of non-planar faults. Minor bugfixes are reflected by changes in the input syntax for time integration (Newmark/HHT), receiver locations, and linear distributions.
Release Notes: This version introduces a velocity and state dependent friction law for dynamic faults, with fast velocity-weakening at high slip rates.
Release Notes: This version includes time-weakening friction for prescribed rupture speed simulations. Parts of the code have been refactored to reduce memory overhead and to improve encapsulation. The CPU time and memory usage estimates have been improved.
Release Notes: This version adds non-linear constitutive equations (continuum damage and Coulomb plasticity), regularization for bimaterial faults, and linear slip faults for SH. The utilities for plotting and manipulating outputs were improved. The documentation has been improved. A major code refactoring now allows easier implementation of new materials, source time functions, distributions, and boundary conditions.
Release Notes: This release adds double couple and seismic moment sources possibly located at interelement nodes, plane wave sources with oblique incidence, and source time functions interpolated from a user supplied file.
