SoilTest can be used to simulate real life soil tests. We demonstrate how to gain better insight in the behaviour of soil models and improve quality of model parameters.

In PLAXIS 3D 2016 the CAD import functionality has been improved, supporting *.DXF, *.STEP and *.brep formats. NURBS surfaces, solids, splines can now be imported easily. Native Autocad solids can be imported without the need of discretizing them into triangulated objects first. This does not only save you time in Autocad, it has benefits for PLAXIS as well. Because of the absence of triangulation, the PLAXIS 3D mesher can more easily create better meshes with less elements for both simple and complex projects, by using the mathematical representations of the imported objects. 

Calculation in PLAXIS 3D 2011 and later: multicore calculations

Since the release of PLAXIS 3D 2011, the user may choose different solver types to solve the matrix equations:

• Picos (multicore iterative). It stands for Plaxis Iterative Concurrent Solver library. Picos is an efficient iterative solver that solves the system of equations in parallel on multi-core processors. It is generally the fastest way to perform calculations.

• Pardiso (multicore direct). It stands for Parallel Sparse Direct Solver. Pardiso is a direct solver that solves the system of equations in parallel on multi-core processors. It is generally the most robust way to solve equations, but it has also the highest memory consumption.

• Classic (single core iterative). This is the iterative solver that has been used in the previous PLAXIS 3D version: PLAXIS 3D2010. It solves the system of equations using only a single core on the processor.

Generate Stratigraphy from imported CPT Logs: The soil layering in a borehole can be specified using available CPT logs. In this video we will demonstrate how to import these into PLAXIS 3D.

This functionality is also available in PLAXIS 2D


 

Remote Scripting API for Input and Output: Since PLAXIS 3D 2013 it is possible to run scripts written in the Python programming language. This functionality enables us to automate the workflow of an iterative design process. We can make quick changes to a model, using pre-defined design parameters. We will create a Python script that generates a model for drivemining. The script includes soil, structure, mesh, staged construction and calculation. This remote scripting functionality is now also available in PLAXIS 2D.
 

Using the PLAXIS Coupling Tool

This video explains how to use the PLAXIS Coupling tool to set up coupled soil-structure interaction analysis between PLAXIS 3D 2016.02 and SAP2000 V18.

Practical use of the commands runner: Pile field

The movie shows how to use the commands runner for more efficient modelling. The generation of a circular pile field was used as example. The commands are set up in a spreadsheet and run in the commands runner.
 

Practical use of the commands runner: using a batch file to run commands
 

This movie shows how to create a command file and use it to calculate multiple projects unattended with help of a batch file.

Sensitivity Analysis and Parameter variation are features for PLAXIS VIP subscribers. They enable us to analyse the influence of variations of parameters on the computational results.

We are excited to announce some major improvements and new functionality in the PLAXIS 3D 2016 release.

• Automatic Generation of staged construction phases for tunnels (PLAXIS 3D)

• Cuboid and (truncated) cone commands (PLAXIS 3D)

• Field stress calculation type

• Tied Degrees of Freedom (2D Dynamics)

• Unlimited number of curve points in Output (PLAXIS 3D)
