# Highlights

The release includes a new finite strain mechanics process, several run time performance optimizations, and new output options.

The LargeDeformation process for finite strain mechanical analysis was implemented. It is set up in a Total Lagrangian formulation. The process uses MFront/MGIS interface for the constitutive relations of the solid, which also takes care of the corresponding pull-back operations. The implementation will be the basis for simulations of large deformation processes, such as salt creep, crushed salt compaction, bentonite swelling or soil mechanics problems.

Optimizations include:

- OpenMP assembly in TH2M/TRM/TRF, configurable `OGS_ASM_THREADS=<n>`.  
**Note** that this might introduce race conditions, so better double-check simulation results when you use this feature.
- CT linear case optimization with speedups of around 10 for certain linear setups.  
Configurable via the `<linear>` and `<linear_solver_compute_only_upon_timestep_change>` prj file settings.  
**Note** : these are expert options; OGS won’t check if it’s valid to use them, this is the sole responsibility of the user.

Output for the users and developers was extended.  
Finer-grained control options for result output (subdomains, variables) were implemented on the user’s side.  
For developers possibility to output assembled local and global matrices is now available.  
It is configurable via the `OGS_LOCAL_MAT_OUT_PREFIX="<some prefix>"`, `OGS_LOCAL_MAT_OUT_ELEMENTS="0 1 5 16 123"` and `OGS_GLOBAL_MAT_OUT_PREFIX="some prefix>"` environment variables.  
The local matrix output is available for all processes, and the global matrix output only for small deformation, TRF, TRM and TH2M at the moment.  
For better tests the `vtkdiff` was extended to compare integration point data. This new feature should be used in newly added CTests.

Other notable changes include, local coupling scheme for staggered processes, and thermo-mechanical part of a freezing liquid was implemented in ThermoHydroMechanics process; hydraulic part to come soon.

# Breaking changes

This section lists changes in OGS that might make OGS terminate due to missing or unused configuration or might change OGS behaviour.

- [!4811](https://gitlab.opengeosys.org/ogs/ogs/-/merge_requests/4811) TRM/TRF vapour properties moved.
- [!4800](https://gitlab.opengeosys.org/ogs/ogs/-/merge_requests/4800) `<media>` used in two phase flow p-rho.
- [!4766](https://gitlab.opengeosys.org/ogs/ogs/-/merge_requests/4766) `<dimension>` configuration removed in HM, LIE/HM, LIE/M, RM, TH2M, THM, TRM.
- [!4699](https://gitlab.opengeosys.org/ogs/ogs/-/merge_requests/4699) `x_dot` renamed to `x_prev` in all assembly routines.  
For new processes developed in private branches this change might entail a silent change of meaning, i.e., the code still compiles, but produces nonsensical simulation results.
- [!4403](https://gitlab.opengeosys.org/ogs/ogs/-/merge_requests/4403) The small deformation process now computes `eps_prev` instead of storing it.

> The only problem appeared for the back-filling (subdomain deactivation) case where a different strain was stored. This is a not so simple issue to be dealt with in the future.

- [!4557](https://gitlab.opengeosys.org/ogs/ogs/-/merge_requests/4557) If some variables are specified for output, only those will be output, i.e., users might miss some outputs compared to before this MR. Please check/adapt your prj files if necessary.
- [!4618](https://gitlab.opengeosys.org/ogs/ogs/-/merge_requests/4618) Three sub-folders of `MeshLib`, `MeshEditing`, `MeshGenerators` and `MeshQuality`, and some other files, which are only for GUI and utilities, are moved out of `MeshLib`
