Mechanics and heat conduction.
Features
The main features of this release is the implementation of two new processes,
the small deformation, and the heat conduction. Some extensions were done to
the DOF table to be able to manage multi-component/multi-variable processes.
Also, during implementation of the Robin boundary conditions, the base classes
for the boundary conditions were generalized.

implementation is based on the Kelvin mapping. #1340 - Added B-Matrices and Kelvin mapping tools for deformation processes. #1359
- Heat conduction process implementation. #1328
- Finalize support for multicomponent boundary conditions adding configuration
parser. #1343 - Added uniform Robin boundary condition. #1336

- Implemented numerical Jacobian assembly for Newton-Raphson solver. #1352
- Added the new parameter type "Group" which can be used for setting material
ID dependent values. #1426 - Added fluid property class and several fluid density and viscosity models
based on it. #1398, #1435 - Enabled solving of axially symmetric problems on 2D meshes for all currently
implemented processes. #1443 - Added time measurement for assembly and solvers. #1322
- Added named functions, out of which expressions can be built up at run-time
from the prj file, which can be used to output additional nodal quantities. #1314, #1315 - Added component-wise norms, and flexible convergence criteria for nonlinear
solvers. #1349, #1342 - Restructured the time loop. #1364
Utilities
New utilities:

the computed data as a PropertyVector with the namenode_aggregated_gwn
into the mesh. The tool also outputs an OGS-5 direct source term (Neumann
boundary condition) data file. #1346 - scaleProperty for simple rescaling of mesh properties. #1347

Release notes
Implementation of several time integration methods and non-linear solver schemes is the major advance in this release. We have chosen to implement a first order implicit quasi-linear system solver for the equations in the form of
The explicit and the implicit Euler, the Crank-Nicholson, and the BDF (second to sixth order) time integration methods are provided. For the non-linear systems, the Picard and Newton methods are available. See implementation details in the doxygen documentation.
Overall stability of the code was improved with recent usage of clang's address and undefined behaviour sanitizers.
Features:

that makes OGS use dynamically.
allocated shape matrices. - Added several cmake options for selecting which element types, dimensions and
orders to be built. Selecting only few element types speeds up compilation
significantly. #1092 - Added a command line argument of
-l
for OGS cli and testrunner to specify verbosity of logging. #1056 - Added possibility to specify after which timesteps there shiuld be output.
- Added possibility to specify timesteps of different size for use with
transient processes.

The 6th version of OpenGeoSys (OGS) is under way. After single and coupled FORTRAN modules in ROCKFLOW 1+2, the C version 3 with dynamic data structures, the object-oriented C++ parallelized version 4, completed with data integration and visualization tools by version 5; ogs6 - as an open source project - is aimed at performing on supercomputing platforms and providing complete workflows for solving of coupled multi-field problems in real world applications. The major paradigms of ogs6 are being developer-friendly, performing, and user-friendly.
