The CivilFEM with ANSYS Geotechnical utilities were created with the main purpose of becoming a powerful tool to allow civil engineers to deal with the most typical and advanced soil mechanics 2D and 3D problems with any kind of Beam, Shell and Solid elements.

Its intuitive interface allows creating complex structural models and simulating the soil-structure interaction rapidly and in detail, taking into account the nonlinear materials, geometry and contact conditions as well as the design and checking of the structural elements of the projects.

With the capabilities that CivilFEM with ANSYS provides, a wide range of projects can be performed such as: tunnels, dams, piles and micro piles, foundation slabs, geotextiles-geogrids, reinforced soils, retaining structures, etc.
