midas GTS is a Geotechnical and Tunnel analysis System, based on state-of-the-art finite element and graphical technology.

midas GTS enables the engineers to intuitively generate complex geotechnical models. Outstanding geometrical modeling and meshing features are complemented by powerful analysis capabilities and a fast Multi-frontal solver able to handle large 3D models.

midas GTS has been scrutinized by a strict QA/QC system ensuring a high standard of quality.

midas GTS defines a new paradigm for tunnel engineering and geotechnical structures.
