Overview

This release features the implementation of the Thermo-Hydro-Hydro-Mechanical (TH2M) fully coupled process. The process is intended for modeling two-component two-phase flow in deformable porous media under non-isothermal conditions. Testing is in progress and development continues, so handle with care or wait a little longer until it got more refined.

Another new process, the StokesFlow process, is mainly used for simulating the low-Reynolds-number incompressible flow in fractures. The Stokes equations are solved using the standard Taylor-Hood scheme. Additionally including the Darcy term in the momentum balance equations, the StokesFlow process module is capable of modeling the fluid flow in fractured porous media.

The local assembly on inclined elements, which can be used to simulate the fluid low in fracture, are implemented. As a first application, LiquidFlow is enabled to use such local assembly.

Also work continued on new material models, e.g. the Günther Salzer model for transient and stationary rock salt creep, an improved HDF5-based output file handling which allows for parallel postprocessing as well as the introduction of a first iteration of a Jupyter Notebook based user workflow. Stay tuned for more on interactive computing in future releases.
