ZSoil Day 2026 – Presentations
Numerics in Geotechnics & Structures 2026 brought together ZSoil users, engineers and researchers on 28 August 2026 at HEIA in Fribourg, Switzerland.
This year’s presentations cover a broad range of practical and research applications, including deep excavations, masonry structures, seepage and stability, spatial geotechnical modelling, geothermal foundations, digital twins, probabilistic analysis, AI-assisted workflows and new ZSoil developments.
The presentations from the four technical sessions are available below.
