    PLAXIS 2D Command compatibility notes

    Application PLAXIS 2D
    Version PLAXIS 2D - all versions
    Date created 28 July 2014
    Date modified 28 February 2023

    PLAXIS 2D 2023.1

    Soil/Rock

    For soil/rock material definition the reference elevation on the vertical axis above which the Young's modulus is equal to the reference value have been updated to follow the CamelCase formatting.

    V22.02 2023.1
    .verticalRef .VerticalRef

    PLAXIS 2D CONNECT Edition V22.02

    Plates

    For plate material definition the unit weight and the thickness properties have been updated.

    V22.00 V22.02
    .D2D .d
    .W .w

    User-Defined Soil Models

    The enumerated value for a User-Defined Soil Model (UDSM) type is now again in V22.02. This was reverted back from the value in V22.00.

    For command logs and Python scripting you are recommended to use the string-based property value instead: "User-defined"

    _set SoilMat_1.SoilModel "User-defined"

    PLAXIS 2D CONNECT Edition V22

    Material definition

    The material definition for soil/rock and structures has been enhanced. The changes concern:

    • new categories and updated structure in the material data set window (GUI)
    • updated property names (GUI and command line)
    • material definition requires property name-property value pairs (command line)
    • live material definition validation on the side panel (GUI)

    For material properties changes, i.e., on objects and commands, check the Commands reference under the Help menu in both Input and Output.

    Embedded beams

    The structural element is now called Embedded beam, instead of embedded beam row.
    The following commands are removed from PLAXIS 2D:

    • embeddedpilerow
    • embeddedpilemat

    Instead, to create an embedded beam structural element and its material the following commands can be used:

    • embeddedbeam
    • embeddedbeammat

    The following command will be deprecated in favour of the embeddedbeam command:

    • embeddedbeamrow

    Undrained behaviour is renamed to Excess pore pressure calculation

    The soil material category has been updated to better describe the group of properties that can simulate an incompressible soil by selecting the determination of the excess pore pressures to be based on a v-undrained definition, Skempton B based or following the Biot effective stress concept (αBiot).

    PLAXIS 2D 2018.00

    Output

    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:

    • getcurveresults
      • 2D 2017: getcurveresults Node_A Phase_5 ResultTypes.Soil.Ux
      • 2D 2018: getcurveresults CN_1 Phase_5 ResultTypes.Soil.Ux
    • getsingleresult
      • 2D 2017: getsingleresult Phases[4] ResultTypes.Soil.Ux Node_A
      • 2D 2018: getsingleresult Phases[4] ResultTypes.Soil.Ux CN_1
    • getcurveresultspath
      • 2D 2017: getcurveresultspath Node_A Phases[0] Phases[3] ResultTypes.Soil.Ux
      • 2D 2018: getcurveresultspath CN_1 Phases[0] Phases[3] ResultTypes.Soil.Ux

    Note that for all commands you can also use Curvepoints.Nodes[0] 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.

    PLAXIS 2D 2017.00

    Input

    Select points for curves

    The command __selectcurvepoints is no longer available. Instead, the following commands can be used:

    selectmeshpoints
    /output addcurvepoint "Node" (x y z)
    /output addcurvepoint "StressPoint" (x y z)
    /output update

    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:

    2D 2016 2D 2017
    .Deform.SumMWeight .Deform.SumMweight
    .Deform.Loading.SumMStage .Deform.Loading.SumMstage
    .Deform.Loading.SumMWeight .Deform.Loading.SumMWeight
    .Reached.ReachedTime .Reached.Time
    .Reached.ReachedStiffness .Reached.RelativeStiffness
    .Reached.ReachedForceX .Reached.ForceX
    .Reached.ReachedForceY .Reached.ForceY
    .Reached.ReachedPMax .Reached.Pmax
    .Reached.ReachedMStage .Reached.SumMstage
    .Reached.ReachedMWeight .Reached.SumMweight
    .Reached.ReachedMsf .Reached.SumMsf

    PLAXIS 2D 2016.00

    Input

    Switch to Flow conditions mode

    The gotowater command is pending deprecation in favour of the gotoflow command

    Tunnel designer

    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.

    Output

    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

    Soil results

    In 2D2015, there was a typo in the soil result objects related permeability. These have been now fixed:

    • ResultTypes.Soil.RelPermeability
    • ResultTypes.Soil.ActualPermeabilityX
    • ResultTypes.Soil.ActualPermeabilityY

     

    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:
        embeddedbeammat

    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.

    Bending moment

    Since PLAXIS 2D AE.02, the parameter for the Point Load's bending moment has been changed from BendingMoment to simply M

    Interface side

    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.
