PLAXIS 2D 2018.00
Commands using curve points
Following the support for an unlimited number of points for curves in Output, the following examples show the commands that have been updated:
- 2D 2017: getcurveresults Node_A Phase_5 ResultTypes.Soil.Ux
- 2D 2018: getcurveresults CN_1 Phase_5 ResultTypes.Soil.Ux
- 2D 2017: getsingleresult Phases ResultTypes.Soil.Ux Node_A
- 2D 2018: getsingleresult Phases ResultTypes.Soil.Ux CN_1
- 2D 2017: getcurveresultspath Node_A Phases Phases ResultTypes.Soil.Ux
- 2D 2018: getcurveresultspath CN_1 Phases Phases ResultTypes.Soil.Ux
Note that for all commands you can also use Curvepoints.Nodes instead of CN_1 to retrieve the results for the first selected node.
Phase/Step object compatibility
For more information on the changes in the properties for Phase and Step objects in PLAXIS Output program see PLAXIS Output Phase/Step object compatibility for details.

Select points for curves
The command __selectcurvepoints is no longer available. Instead, the following commands can be used:
For more information, you can check the article Select points for curves prior to calculation directly in Input.
Phases object updates
The phases object in Input has been updated. Below you can see the differences in properties between the versions:

PLAXIS 2D 2016.00
Switch to Flow conditions mode
The gotowater command is pending deprecation in favour of the gotoflow command
In the tunnel designer a few things changed such that older command logs might not properly work:
- the order of generated elements in Tunnel Designer has changed so this will not generate proper geometry or correct references when assigning e.g. plates, interfaces and line loads to these when using old command logs;
- Names of the generated properties in Tunnel Designer (e.g. lineloads, plates) changed as well, for instance in the tunnel designer a line load was called Lineload_x while now is called TCS_x_LineLoad_x
Phases - dynamics
The time stepping settings for dynamic calculations has changed: we can now choose a new time step determination: "Semi-automatic" which behaves the same as the "Automatic" setting of PLAXIS 2D 2015. The "Automatic" setting is now fully automatic and should choose an appropriate number of dynamic substeps AND number of additional steps.
Phase info inconsistencies with Input
We found a few inconsistencies between Input and Output for some parameter names from the Phase and Step info. Of course we would like to have consistency between the two programs to make sure that the parameters are easy to use and to make sure any scripting/Python programming is easier to make and understand.
The changed parameter names are:
|description||2D 2015.02||2D 2016.00|
|Phase identification name||Phase_1.Caption||Phase_1.Identification|
|internal phase number||Phase_1.ID||Phase_1.Number|
|time interval for last step [in project time unit]||Phase_1.Info.TimeInterval||Phase_1.Info.TimeInterval|
|reached total end time of phase [in project time unit]||Phase_1.Info.EstimatedEndTime||Phase_1.Info.ReachedTime|
|time interval in seconds per step [dynamics only]||Phase_1.Info.TimeIntervalSeconds||Phase_1.Info.TimeIntervalSeconds|
|reached dynamic time in seconds [dynamics only]||Phase_1.Info.ReachedTime||Phase_1.Info.ReachedDynTime|
In 2D2015, there was a typo in the soil result objects related permeability. These have been now fixed:
PLAXIS 2D 2015.00
Embedded pile row changes to embedded beam row
The embedded pile row has been changed into embedded beam row to make clear this embedded beam can be used for more than just piles, e.g. grout anchors.
To create a new embedded beam row:
embeddedbeamrow (x1 y1) (x2 y2)
To create a new embedded beam row material dataset:
Note: in this version the old commands for the embedded pile rows will be supported, but may become deprecated in later versions
Naming of cutobjects (staged construction)
Due to an issue in the sorting routine of the cut objects (i.e. the intersected result of soils, polygons, lines), and the fact that the source of a cut objects was not clear in its naming, the automatic naming of items in the intersected geometry (mesh mode, flow conditions mode, staged construction) has been changed. This also involves removing the prefix CS_ for these items, see this example:
- PLAXIS 2D AE: CS_Line_1
- PLAXIS 2D 2015: Line_1_1
Multiplier on vector based features
The name for the multiplier userfeature has been changed. For point loads and point prescribed displacements, this userfeature name has been changed from .Multiplier_x/_y/_z to .MultiplierFx/Fy/Fz. To set a LoadMultiplier for a dynamic point load using the command line:
- 2D AE: set DynLineLoad_1_1.Multiplier_x Phase_1 LoadMultiplier_1
- 2D 2015: set DynPointLoad_1_1.MultiplierFx Phase_1 LoadMultiplier_1
For line loads, this userfeature name has been changed from .Multiplier_x/_y_z to .Multiplierx/y/z, and this would be the command line:
- 2D AE: _set DynLineLoad_1_1.Multiplier_x Phase_1 LoadMultiplier_1
- 2D2015: _set DynLineLoad_1_1.Multiplierx Phase_1 LoadMultiplier_1
Linear boundary conditions for head, inflow and outflow
Linear boundary conditions for head, inflow, outflow had inconsistent settings. Now the behaviour can be chosen more explicitely and more consistently by offering these options:
- "Vertical increment"
- "Horizontal increment"
- "Start/end values"
The option Linear is deprecated in 2D 2015, and replaced by the above mentioned options.
PLAXIS 2D AE.02
This page contains an overview of the changes in commands.
Since PLAXIS 2D AE.02, the parameter for the Point Load's bending moment has been changed from BendingMoment to simply M
By fixing the issue called Local axis may flip with overlapping lines in PLAXIS 2D AE. the positive and negative interfaces may be on the opposite side of the line (and plate) compared to command log files created in PLAXIS 2D AE.00 or PLAXIS 2D AE.01. This could influence the replaying of these command log files.
