Process’ changes

TH2M

• !5340 Pass mechanical strain to permeability.
• !5415 Total sigma output.

ThermalTwoPhaseFlowPP

• !5378 Fix: The molar mass is not set for gas density or pressure models.

HeatTransportBHE

• !5215 Add an advanced BHE <flow_and_temperature_control> for incorporating heat pump characteristics for heating, hot water and cooling: <AdvancedBuildingPowerCurvesFlowCurve>.

LIE

• !5400 LIE/HM multiple fracture preparations.

Richard’s mechanics process

• !5052 RichardsMechanics Initialize nonzero Stress State for Solid Models.

SmallDeformation

• !5369 Strain data at IP are not initialized in SmallDeformation.

ThermoMechanics

• !5372 Initialized strain IP data with Bu.

Parameters

• !5392 Added support for inline parameter definitions in project files. Parameters can now be specified directly as constant values inside property definitions, e.g., <dry_thermal_conductivity>0.5 0.3 0.2</dry_thermal_conductivity> instead of only referencing predefined parameters like <dry_thermal_conductivity>lambda_dry_bentonite</dry_thermal_conductivity>.

Generic features

• !5290 Point-to-point anchors can now be defined between point within elements.
• !5337 Anchor elements can be pre-stressed and obey a simple friction law.
• !5376 Release nodal force boundary condition.
• !5381 Dirichlet boundary condition with time-dependent decay.

Tools

• !5330 Extend tool createLayeredMeshFromRasters.
• !5355 Add mergeMeshToBulkMesh.
• !5405 Bundle apply_xmlpatch tool. Same logic as patching with ogs executable.

Python & Jupyter

• OGSTools updated from 0.6.0 to 0.7.0, see Release notes
• !5338 Logs - normalize logs when OGS is called from Python.
• !5356 Added missing binaries to wheel, e.g. xdmfdiff and pvtu2vtu.
• !5399 , !5387 Refactored dependency handling of notebooks for development and CI. Migrated to a uv -based workflow. Now requires uv for OGS_USE_PIP=ON!
• !5406 [Python|OGSMesh] Add required functionality and fix bug outputting every time step.

Testing

• !5156 [F-bar] Jupyter Notebook test of Cooks membrane and other tests.
• !5307 From DFN generation in PorePy to reactive transport modeling in OGS.
• !5319 Interactive McWhorter benchmark.
• !5370 GreatCell benchmark suite HYDRO_MECHANICS_WITH_LIE.
• !5373 GreatCell benchmark suite HM_PHASE_FIELD.
• !5389 GreatCell benchmark suite, Hydraulic fracturing, HM_PHASE_FIELD.
• !5390 Adds a tutorial for 1D reactive-transport model.
• !5404 [T] update and polish some CT and RT jupyter notebooks.
• !5417 Modifying B-bar test for GreatCell HM-LIE.
• !5420 Fix k-regime benchmark run in PhaseField process.

Bug fixes

• !5334 Fix a bug in pvtu2vtu tool.
• !5419 PETScVector: prevent setting or adding entries from an empty vector.
• !5423 Fix hydraulic residuum names LIE-HM/THM/LF.

Infrastructure

• !5350 , !5354 Guix manifest definitions. Now you can create an apptainer development container with the current sources for archival (around 2.5 GB in size) and later re-compilation with guix time-machine -C scripts/guix/channels.scm -- pack -f squashfs -m scripts/guix/manifest-dev.scm.
• !5361 Some minor infrastructure enhancements.
• !5375 TCLAP argument comment additions (auto galaxy wrap preparation).
• !5403 [CI] Reduced pipelines.
• !5430 Packages ogs-serial and ogs-petsc are now in official Guix starting from Guix commit 5d31f8f406751919004ee3ae1ec3c9fcf3c3ae16 . This enables to run the latest ogs release (currently 6.5.5, this release follows shortly) on systems with Guix installed with e.g. guix shell ogs-petsc -- mpirun -np 4 ogs ....
• !5433 Switch OpenMP_RUNTIME_MSVC to experimental (was llvm). The llvm-runtime is not redistributable so we switched to the integrated runtime of Visual Studio.
• !5436 Unify logging and improve spdlogger initialization.

File I/O

• !5349 Pass initial time to HdfWriter.

Material Property Library (MPL)

• !5392 Enable optional inline parameters for MPL property SaturationWeightedThermalConductivity.

Core functionality

• !5339 Remove PropertyVector->std::vector inheritance.
• !5357 Change default MPI communicator.

Fixes

• !5274 Fix possible segfault when linear solver fails.
• !5380 Address VTK-9.5 deprecation warnings.
• !5383 Fix two errors in IterationNumberBasedTimeStepping.
• !5384 Work around library loading issues and test shared lib loading.
• !5391 Small improvements in TimeStepAlgorithm.
• !5398 Fix rare bug in identify subdomain.
