6.2.1

Features

New processes

• A thermo-hydro-mechanical (THM) process, monolithic implementation for Newton non-linear solver. #2446

Other process' changes

• Non-equilibrium initial state in the small deformation, HM, and TM processes. #2501, #2561, and #2544
• A reactive transport process, integrated IPhreeqc Module 3.5.0 for reactive transport modeling. #2494, #2512
• Fix velocity output in HM. #2507
• Store process' names in the Process class instead of an outside map. #2534
• Generalize permeability models for the fracture flow in LIE/HM:
  • CubicLaw (just generalization). #2542
  • ConstantPermeability. #2543
• Add simple mass lumping to the RichardsMechanics. #2590

Numerics

Parameter

• new TimeDependentHeterogeneousParameter. #2588
  Feature can be used for time dependent heterogeneous boundary condition or source term specification.

Boundary condition

Source term

Input and output

• HT process: Use MaterialPropertyLibrary for solid phase properties, too. This makes it necessary to changed the project files. #2487
• Reactive transport process: Output time-series amounts of kinetic reactants and equilibrium phases defined under the subtree of chemical system. #2564

Material models

• Orthotropic elasticity model. #2428
• Dupuit permeability relation. #2330

File I/O

• Gocad TSurface reader has been added #2547
• Gocad PLine reader has been added #2586

Testing and documentation

New tools

• GocadTSurfaceReader command line utility #2547/#2586

New tools and CLI usage

• Add switch multiple-nodes-allowed to tool constructMeshesFromGeometry, #2459
• Add option to vtkdiff tool to compare meshes using absolute tolerances and connectivity, #2485
• Scalar arrays are copied when using the ExtractSurface-tool, #2492

Data Explorer

• Mesh to shape export is now writing all cell-based scalar arrays to the DBF-file, #2436
• Added support of world files to georeference arbitrary raster files, #2460
• Scalar arrays are copied when extracting mesh surfaces, #2492
• Gocad TSurfaces can be imported into Data Explorer #2547
• Gocad PLines can be imported into Data Explorer #2586

Other notable code changes

• Conversion to linear mesh is now independent of node numbering. #2519
