  • Interface detached in the output

    Hi all, I am trying to simulate the curling of pavement subjected to temperature differentials at the top and bottom. In the contact surface of the concrete and base course, I defined interfaces and put Rint in the concrete as 0.01 to allow higher seepage…

  • Interface stiffness defined by "Direct"

    Dear Support Team, When I applied extremely low ks & kn values for a sensitivity check, I found a gap at the interface before activating the interface element . I suspect that ks & kn values defined by "direct" are applied to the interface element…
  • Interface value

    Hi all, I have some questions regarding the interface elements in Plaxis. 01. Soil interface elements is used to represent the soil structure interaction. These interface elements reduce strength and stiffness. Based on reference manual it is stated…
  • How to model bedrock

    Hi! I am modelling a foundation on blasted rock (thickness about 4 m) on top of bedrock. How do I easily and best model the bedrock? Currently I have modelled a fixed line displacement as bedrock, and I have added interfaces (r_inter=0,8) between blasted…
  • Interface Soil/Soil

    Hi PLAXIS community, I would like to ask you about the soil-soil interface, please. If I want to choose the formula for elastic sliding, which is determined by the elastic shear stiffness of the interface and the function of the interface thickness…
  • Embedded Beam Row Permeability & Skin Friction

    Hello, I have a couple of questions regarding the embedded beam row: How can I make an embedded beam row impermeable (i.e. so water has to flow around the base of the wall)? When specifying the skin friction in the input program I am assuming…
  • lateral soil slippage at the sides of the pile

    Hello, Can anyone please help as how can I model " lateral soil slippage at the sides of the pile" using embedded beam in PLAXIS. Thank you, Faisal
  • Lateral resistance of embedded beams

    Hello, I have a question regarding the applicability of lateral resistance in piles. In many research works, I have seen it mentioned that " PLAXIS does not account for lateral resistance/slide for embedded beams". But in the software, I see I can…
  • Problem to visualisation any axis or geometry on PLAXIS LE 2D slope stability

    Hello, I can´t visualize any axis or geometry on PLAXIS LE 2D slope stability. Already re-installed and change the version of PLAXIS LE 21.00.00.95 to V 21.05.00.043. The windows view is always blank, but when I use the command “print to PDF” I can…
  • Model visualization problems

    Hello everyone, I'm approaching plaxis 2D LE software. I'm trying to open models from Plaxis LE Manager, but when I open them I cannot see anything in the 2D LE software. I've just a white screen. Can someone help me? Thank you
  • Meshing Issue - Overlap of mesh at interfaces on mesh view.

    When refining my mesh after checking it is clear of any issues with geometry and selecting "View Mesh" I get this: An overlap between the interface and plate section - this area of the mesh looks incorrect and as if it is folding on itself. Interestingly…
  • Line segment missing in Plaxis Python interface

    When requesting the Line input objects via the Python interface, I noticed that it returns a segmented line, not the single line that you put in through the GUI. Is it possible to get the Python interface to return the single line that you put in yourself…
  • irregular high peak of stresses alona cut off wall

    Hi, by displaying the principal stresses of a line cross section in the middle of a cut off wall an irregular peak of stress keeps showing. The Plaxis Reference suggests adding interfaces to solve the problem of stress oscilations at the corners of…
  • How to get Rinter value

    Referring to the question and answer about Rinter ( https://communities.bentley.com/products/geotech-analysis/f/plaxis-soilvision-forum/212033/rinter-value ) We typically do not recommend parameter values as this should be based on data collected…
  • PLAXIS 2D: Tutorial 08 Questions regarding the interfaces

    Hi all, I have several questions regarding Tutorial 08 for PLAXIS 2D. 1. There seems to be a gap between my footing and upper interface. Although I have tried to merge equivalent geometric objects, it was suggested that "no equivalent geometric objects…
  • UDSM for Interfaces

    Dear Plaxis/Bentley community, we are working on soil-geogrid interaction and want to apply user-defined properties to the interface via a UDSM. The overall goal is to update the shear stiffness of the interface elements in each calculation step depending…
  • PLAXIS fails to model MC frictional interfaces in dynamic conditions.

    I have tried validating PLAXIS 2D for the very simple case of a block connected through a linear-elastic perfectly plastic Mohr Coulomb interface to an oscillating base. The model consists in a large soil cluster of linear elastic material (the oscillating…
  • Plaxis 2D snap to crossing

    Hello. In the Plaxis 2D v2019 one could move endpoint of line and it would snap to the crossing of two other lines - a green circle appers when hovering over crossing (left side of picture below). In Plaxis 2D v2020 I can only snap to one or other line…
