%0 Misc %D 2015 %T PyLith v2.1.1 [software] %A Aagard, Brad %A Williams, Charles %A Knepley, Matthew %I Computational Infrastructure for Geodynamics %K PyLith %X This release provides a few new small features and bugfixes.Migrating from v2.0 to v2.1The points file for OutputSolnPoints must now contain station names asthe first column.Release NotesStation names are required for output at arbitrary points(OutputSolnPoints) and are included in a /stations dataset in HDF5files.A progress monitor will update a text file with the progress of asimulation (time in the time stepping loop or the number of impulsescompleted) and given an estimate of when the simulation will becompleted.Bug fixesA few bugs related to creating cohesive cells for faultintersections have been fixed. Faults can now meet at Tintersections provided the buried edges of the faults areclamped. In other words, the fault ending at the T intersectionhas a clamped edge along the intersection. The fault ending at theintersection must also come AFTER the through-going fault in thelist of fault interfaces.There have been two major bug fixes for Drucker-Prager plasticity,for both DruckerPrager3D and DruckerPragerPlaneStrain. The first fixwas a missing initial pressure term for the plastic multiplierin the Drucker-Prager formulation. This affects plasticitycalculations when initial stresses are used. The error has beencorrected in the code, the manual, and the unit tests. The secondbug was an incorrect test for tensile yield that could causePyLith to exit with an error when plastic yield had not actuallyoccurred. The error would only occur when the allowtextittensileyieldflag was set to False. This bug has been fixed in the code, and thenew test is also described in the manual. This should preventproblems that previously existed when allowtextittensileyield was setto False (as it should be for most quasi-static problems).Fixed bug in DataWriterHDF5Ext associated with multiple processeswriting information to the HDF5 file. With external datasets theHDF5 file is limited to metadata and is maintained by process 0.A two-dimensional gravity example has been added, based on thetutorial from the June, 2014 workshop at Stanford University.The tutorial itself is in examples/2d/gravity, and a new sectionhas also been added to the manual describing the example.Fixed inconsistent fault orientation when running in parallelfor 2-D domains.
