Multi-purpose finite element
software for geotechnical professionals


Thousands of installations worldwide
New Features in ZSoil 2026


ZSoil
is the Windows-based finite element software that offers a unified approach to numerical simulation of soil and rock mechanics, above-ground and underground structures, excavations, soil-structure interaction, and underground flow, including dynamic, thermal and moisture-migration analyses. ZSoil is available for Windows 10 & 11.

ZSoil is an integrated software package offering a unified approach to the natural processes encountered in geotechnical and foundation engineering, including stability, consolidation, creep and underground flow, excavations, and soil-structure interactions. Typical engineering problems addressed worldwide with ZSoil include foundation and earthworks construction, tunnels, underground storage facilities, metro stations, mining, highway and railroad cuts and fills, dams, temporary and permanent retaining structures, waterfront structures, excavation systems with complex construction sequences, hydraulic structures, and buildings.

ZSoil is a continuously upgraded finite element software package for geotechnical, foundation, and underground-flow engineering, developed for Microsoft Windows environement. The program has been used in forensic analysis and design studies, covering a wide range of scenarios encountered in real-world case studies.

ZSoil was been developed by Zace Services Ltd from 1982 to 2022. Since 2022, its development has continued under GeoDev Sàrl. The latest versions were developed by a team led by A.Truty, K.Podles & Th.Zimmermann, with research experience at the Swiss Federal Institute of Technology (EPFL), U.C.Berkeley, and Caltech.
