HI I have an existing PLaxis 2D model, and i am interrogating the model via python to get all the information out. For the structural elements and soil elements etc this is straight forward, however I am not having much luck to extract the information…

Hi, I just wanted to ask a general question. In Plaxis 2d materials models manual, it say not recommending practical applications of the Modified cam clay model, could anyone give a more detailed explanation? The practical application even not recommended…

Getting the above error

Hi, I'm working on the seismic behavior of a T-shaped retaining wall. However, the dynamic calculation of the Plaxis 2D FEM model shows non-physical negative values in the total interface stress profile (wall-backfill material) in an active earth pressure…

Hello, I need to use the Plaxis script to get the result but I have this error (No module plxscripting) in the script! I did below steps: 1- Activated remote scripting server 2- Started SciTE editor 3- Included boilerplate below: from plxscripting. easy…

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…

Why is the acceleration time graph high in the first seconds in the outputs of dynamic analyzes?

Hi everyone, I am working on a consolidation analysis using the Soft Soil Creep model to assess the long term settlement of a deep, normally consolidated clay layer due to the load of a building. I calibrated my const. model parameters based on a consolidation…

Hi everyone, I have developed an API code that involves solving a minimum of 20,000 models through algorithms and related loops. This process typically takes approximately three weeks. In order to expedite this time-consuming procedure, I am interested…

I would like to know if altering the Mweight factor before a dynamic calculation will affect my results (Mass calculation and gravity constant). It is my understanding that the Mweight only affects the unit weight. Am I correct? Thank you.

Hi all, I have a problem that I'm trying to model in PLAXIS 2D and I'm a little uncertain about how to model the pile cap beam. Below is the geometry of the problem. For the batter piles, I'm modelling them as embedded beam rows. I would like to…

Hello everyone, I was wondering if it's possible to insert paragraph of command lines instead of entering them one by one in the command section ? It would be super convenient and faster to do that. Thank you

I am performing the pressuremeter test that comes in the Material Models manual, section 17.2.3 pressuremeter test, but the mesh that I obtained does not look like the one in Figure 90, and in the calculation stage, it is not resolved. I believe that…

Hello, Just a quick question about axisymmetric modelling in Plaxis2D: 1) When inputting data and also reading the outputs in an axisymmetric model in Plaxis, you need to divide the input force and multiply the output forces by 2*pi to account…

Please , can any one help me how to model Accrapods or tetrapods in plaxis 2d ?

Am trying to model the effect of thermal loading on the backfill behind integral abutment by using Plaxis 2D. I modelled the concrete bridge deck as Linear Plate element and provide a prescribed displacement near the top of the abutment. The applied displacement…

Hi there, I am trying to find a way to extract the structural force in volume plate using python for multiple phases and multiple volume elements. I understand there is option in Tool (structural forces in plate volume) and you can define the centreline…

Is there an official Plaxis reference or literature reference supporting the use of non zero cohesion and tensile strength (eg 1 kPa), to improve numerical calculation?

Hi all, Based on Maayne and Kulhawy, the ko,oc relationship is shown below. For Plaxis, the following relationship is used Can I know the source for this one? Thanks.

Hi, I want to evaluate the stress on subgrade soil induced by the curling of concrete pavement resulting from temperature variations. Does the Plaxis have the option to evaluate the deflection of concrete due to temperature variation? Thanks in advan…

Hello, I have come across a problem where the raft foundation is resting on clayey silt. Ground water table is not encountered and soil at the site has a free swell index of 140-210 at 2.5 to 5m depth from EGL and foundation is at 3m below EGL. what…

Hi, I am trying to model the dowels between the structural plates of central wall in a tunnel as embedded beam. The plates are vertically standing with no contact with the soil. Is this a correct modelling approach to move forward with. I understand…

Hi all, In the flow analysis, the cross-section is cut through (2,11) and (5,11) for qy and iy as shown below. This is the homogeneous soil with kx=ky=0.6221 m/day. here q=ki and left side of flow qleft = iyleft * k = 0.2063 * 0.6221 = 0.12834…

I am simulating the process of pipe burst induced groundwater flow in an unsaturated slope (see simplified sketch in Figure 1 below). According to the according to the k-function curve, a lower limit of soil suction will make the soil more permeable at…
