Support for GNU Autoconf will be removed in the next release of
ParFlow. Future releases will only support configuration using CMake.
- New overland flow boundary conditions
- Flow barrier added
- Support for metadata file
- Boundary condition refactoring
- Bug fixes
- Coding style update
Three new boundary conditions as modules - OverlandKinematic, OverlandDiffusive and Seepage.
OverlandKinematic is similar to the original OverlandFlow boundary condition but uses a slightly modified flux formulation that uses the slope magnitude and it is developed to use face centered slopes (as opposed to grid centered) and does the upwinding internally.x. See user manual for additional information on the new boundary conditions.
New test cases were added exercising the new boundary conditions: overland_slopingslab_DWE.tcl, overland_slopingslab_KWE.tcl, overland_tiltedv_DWE.tcl, overland_tiltedV_KWE.tcl, Overland_FlatICP.tcl
Two new options were added to the terrain following grid formulation to be consistent with the upwinding approach used in the new overland flow formulation these are specified with the new TFGUpwindFormullation keys documented in the manual.
For both OverlandDiffusive and OverlandKinematic analytical jacobians were implemented in the new modules and these were tested and can be verified in the new test cases noted above.
Ability to create a flow barrier capability equivalent to the hydraulic flow barrier (HFB) or flow and transport parameters at interfaces. The flow barriers are placed at the fluxes as scalar multipliers between cells (at cell interfaces).
Flow barriers are set using a PFB file, see user manual for additional information. The flow barrier is turned off by default.
A metadata file is written in JSON format summarizing the inputs to a run and its output files. This file provides ParaView and other post-processing tools a simple way to aggregate data for visualizations and analyses.
Metadata is collected during simulation startup and updated to include timestep information with each step the simulation takes. It is rewritten with each timestep so that separate processes may observe simulation progress by watching the file for changes.
Fixed segmentation fault when unitialized variable was referenced in cases with processors is outside of the active domain.
The framework for boundary conditions was significantly refactored to provide a macro system to simplify adding new boundary conditions. See bc_pressure.h for additional documentation.
The Uncrustify coding style was updated and code was reformated.
