Plaxis (sometimes stylised in all caps; Plane strain and axial symmetry, indicating the geometric types handled in the original code{{Cite web|url=https://www.abbreviations.com/PLAXIS|title=What does PLAXIS stand for?|website=www.abbreviations.com|accessdate=March 25, 2023}}) is a computer program that performs finite element analyses (FEA) within the realm of geotechnical engineering, including deformation, stability and water flow.{{cite book |last=Chalmovský |first=Juraj |date=2014 |title=Základy matematického modelování v geotechnice s využitím programu Plaxis |location=Brno |publisher=Vysoké učení technické v Brně, Fakulta stavební |language=cs|isbn=978-80-214-4938-1}} 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.
