New numgeo release

We have now released a new numgeo version, with plenty new features, bugfixes and new examples.

In particular, we have added:

• An example for a 3D monopile simulation using the HCA model
• Examples for infiltration problems using the 3-phase elements in numgeo.
• A simulation of a 3D pile with comparison of the results to a commercial code

Some specific new features:

• Compliant base boundary conditions
• Including external files in input file
• AVISA-2022 (thanks to Merita Tafili!)
• Karlsruhe hydraulic model (soil water retention curve accounting for void ratio dependence and scanning curves)
• Modified Cam-Clay (”Terzaghi”- and ”Butterfield”-version)
• Matsuoka-Nakai model (thanks to Christoph Schmüdderich!)
• Support of (arbitrary) user-defined external solvers
• Variable bishop effective stress parameter

The keyword reference manual contains a list of bugs we have resolved since the initial release.
