At this point, only used for parameters of fault constitutive models.
Output into a single HDF5 file or an HDF5 file with raw binary files for the datasets. Datasets are written using MPI I/O if available in both cases. Add .Xdmf metadata files associated with HDF5 files to permit reading of HDF5 files with ParaView and Visit.
Added numerical damping via a viscosity parameter that is independent of the bulk constitutive model. The viscosity is applied during the time integration.
Will reduce memory use and provide speedup due to better use of memory cache.
Permit users to stop simulation before time stepping in order to diagnose parameter settings.
Create Nucleation object with spatial and temporal perturbation of tractions from initial value
Permit running large problems where the mesh cannot fit on a single compute node.
Will provide significant speedup to simulations run by many users because most are running on desktop machines that have GPUs.
Moment tensor point sources provide a mesh independent deformation source that is better suited for Green's function calculations than slip on a fault surface via cohesive cells.
Use fault constitutive model to control slip on fault except during episodes of prescribed slip. Need some way to describe when to turn on/off prescribed slip.
