Plaxis (sometimes stylised PLAXIS, Plane strain and axial symmetry, indicating the geometric types handled in the original code[1]) is a computer programme that performs finite element analyses (FEA) within the realm of geotechnical engineering, including deformation, stability and water flow.[2] The input procedures enable the enhanced output facilities provide a detailed presentation of computational results. PLAXIS enables new users to work with the package after only a few hours of training.
