This is the first step in becoming familiar with the practical use of PLAXIS 2D.The general procedures for the creation of a geometry model, the generation of a finite element mesh, the execution of a finite element calculation and the evaluation of the output results are described here in detail.The information provided in this lesson will be utilised in the later lessons.
Therefore, it is important to complete this first lesson before attempting any further tutorial examples. The purpose of the exercise is to find the displacements and stresses in the soil caused by the load applied to the footing. With a Bentley Geotechnical SELECT Entitlement GSE (former PLAXIS-VIP) licence, you can use the commands runner to open the.p2dxlog file and to execute all commands in one go, see also this instruction.

Perform dynamic analyses in a user-friendly, efficient, and accurate way regardless of the vibration source or scale. Accurately calculate the effects of vibrations with a dynamics analysis when the frequency of the dynamic load is higher than the natural frequency of the medium. Low-frequency vibrations can normally be calculated with a pseudo-static analysis by default available in PLAXIS. However, for more advanced seismic analysis, choose the PLAXIS 2D Dynamics module. In addition to viscous boundaries, free-field and compliant base boundaries can also be selected to reduce spurious reflections of waves reaching the model boundaries. Calculate excess pore pressure build-up during dynamic excitation with liquefaction models. For soils other than liquefaction susceptible sand, the (Generalized) Hardening soil model with small strain stiffness generally offers a good choice. The time dependent behavior of the load can be assigned through harmonic, linear, or table multipliers. Dynamic multipliers can be assigned independently in the x- and y-directions in PLAXIS 2D Dynamics and x-, y-, and z-directions in PLAXIS 3D Dynamics. With PLAXIS Dynamics, geotechnical engineers can consider the vibration effect on structures and designs to build safer infrastructure.
