OpenGeoSys 6.5.8

Process’ changes

Component transport process / reactive transport process with coupling of Phreeqc

• !5548 The data exchange between PhreeqC and OGS is now using string in the memory as the default option. It should accelerate the simulation for models with large domains.
• !5591 This MR makes OGS-PhreeqC reactive transport simulations to run in either or both OpenMP and MPI environment (hybrid parallelization).

HeatTransportBHE

• !5544 The BHEs flow and temperature control now requires parameters as input. The possible types are simplified to InflowTemperature, Power, BuildingPower and AdvancedBuildingPower.
• !5571 The BHE now can be defined with changing diameter over depth. The flow velocity and thermal resistance calculation will be changed accordingly during the simulation.

HT

• !5693 Refactor HT documentation; update monolithic scheme

ThermoHydroMechanics

• !5628 Add mass balance equation type.
• !5635 Add sigma_ice and ice_volume_fraction ip/avg data output.
• !5617 Extract EquationBalanceType from LiquidFlow and optimize local monolithic assembly.
• !5625 Optimize the computation of the contribution of strain coupling to the RHS.

ThermoRichardsMechanics

• !5574 Separate data and model structs of constitutive models into individual files.

Constitutive relations (material models)

• !5531 Adds the temperature dependent Lu-Mc Cartney WRC.
• !5695 Support for ranges start:end in media ids

Numerics

• !5694 Refactor NonlinearSolver to support multiple solver strategies

Generic features

• !5602 Enables multiple OGS simulations to be started inside the same Python process (but there can be only a single MPI/PETSc OGS simulation in a single Python process).

Tools

• !5609 Add boundary mesh extraction to generateStructuredMesh.
• !5631 Relative tolerance algorithm for search of collapsible nodes.

Python & Jupyter

• !5682 Benchmarks notebooks run now with OGSTools 0.8.1. Now, additionally Python 3.14 is supported.
• !5632 Relax embedded Python venv site-packages validation

Testing

• !5598 Add coverage option to testrunner.
• !5605 Speedup code coverage and include more tests.
• !5633 Add PETSc coverage job.

Bug fixes

!5606 re-enables Jacobian comparisons for processes that use the OpenMP parallelized assembly code. Nevertheless, the compare Jacobian feature is restricted to a single assembly thread to avoid concurrent file write accesses.

CMake

• !5642 Clang (-tidy) preset.
• !5644 Refactored check headers, use FILE_SET.
• !5570 Feature matrix generation integration in build process.
• !5580 Build time header checks.

Infrastructure

• !5652 Adding xdmfdiff to eve PETSc container.
• !5655 Hugo build-dir based.
• !5656 Updated devcontainer config and docs.
• !5658 Refactored publications.

File I/O

• !5471 Re-implement FEFLOWGeoInterface with libxml2.
