PLAXIS is a finite element software package for geotechnical analysis. Engineers use it to model soil and rock deformation and stability, along with groundwater and heat flow. The suite includes products such as PLAXIS 2D and PLAXIS 3D and is sold as licensed software. The product is now offered under the Seequent brand, which the vendor describes as The Bentley Subsurface Company.
PLAXIS is developed by Plaxis B.V. in Delft, the Netherlands. The American company Bentley Systems acquired it in 2018. For a European organisation this means a Dutch developer under US ownership, so the parent falls under US jurisdiction, which can matter for data access and for the choice of hosting environment. The Seequent website links to a privacy statement and a data processing addendum. The sources consulted do not state where cloud data is stored, so that should be confirmed with the vendor before using any cloud feature.
