The extended licenses that can be used in a PLAXIS session can deliver a range of capabilities. A broad summary of these capabilities is described below.

PLAXIS 2D/3D Dynamics

Soil and structures are often not only subjected to static loads due to construction in and on the ground surface but also to dynamic loads. When loads are powerful, like for example earthquakes, they may cause severe damages. In urban areas, vibrations can be generated due to pile driving, vehicle movement, heavy machinery or train travel. With the 2D Dynamics module, PLAXIS can analyse the effects of vibrations in the soil.

PLAXIS 2D/3D PlaxFlow

Users can assign time-dependent variation or fluxes to water levels, model boundaries, or soil boundaries to simulate various complex hydrological conditions. The input of the time-dependent properties are based on harmonic, linear, or table functions. This allows the modelling of seasonal variations of river water level behind embankments and their effect on the overall slope stability. Precipitation, wells and drains can be included in the model, allowing pumping tests or other hydrological applications to be modelled.

PLAXIS 2D Thermal

The thermal module is necessary when the effects of heat flow on the hydraulic and the mechanical behaviour of soils and structures need to be taken into account in geotechnical designs with PLAXIS.

Geotechnical SELECT Entitlements [VIP]

Note: This is formerly known as PLAXIS VIP in legacy PLAXIS 2D and PLAXIS 3D products.

Within the Geotechnical SELECT Entitlements, many specific and extended features will become available. The special extensions are modular enhancements to PLAXIS software. They provide new or extra functionalities, are fully compatible with the base product and are easy to learn.

For PLAXIS 2D and PLAXIS 3D, these features will be available through Geotechnical SELECT Entitlements
