Dear sir/madam, I have a question about maximum step number and sub step number in dynamic analysis. For example, when we give an input motion (which has a duration of 33s and time interval of 0.01s) into to model, a) Setting the maximum step number…

Hi all, Any idea how to model this one in Plaxis 2D and what type of analyses are needed to do for stability check of the slope proteced by geo-cell and having surface and horizontal drains? Thanks.

Hi all, I created a 2D Plaxis model where we have a tunnel 16m under the surface. The water level is 11m above the ridge. In the construction state, the water is drained 4m around the tunnel. I have tried to model this with a dry zone around the tunnel…

I am very new to plaxis and i am trying to understand modeling a retaining wall (from my understanding this is done using a plate element), i have a general idea of the steps but the values to input are giving me some trouble. I want to model steel sheet…

I am currently working on a liquefaction analysis using the PM4Silt and PM4Sand models for a layered soil model in PLAXIS 2D. However, I have encountered an issue where the liquefied points are observed in the static stage only before the dynamic analysis…

Hello All, I am trying to use the soil parameter optimization based off the soil testing module in PLAXIS. I see for doing this, first I need a "Reference curve" (in the example, it shows as 100 kPa). I believe that is a real time lab data and not…

Hello, I've noticed an unreasonable difference of the maximum value and minimum value of groundwater flow when changing between the shadings and arrows views as presented below (0.7910 vs 0.9002). Is it because one is showing the value for a stress point…

I download the PLAXIS LE 2D sofware but the graphics are not similar to PLAXIS 2D. I need to know if it can be automatize to run a lot of models at once.

In the model, when the peak model is drawn on the node 2650 acceleration-time graph, it also shows abnormal behavior on the acceleration time graph. I couldn't find the cause of the problem.

Hi, is it possible to define a strength parameter (such as cohesion and friction angle) as a function of the deviatoric strains? There are two acceptable options: 1. The parameters are updated along with the strains during the analyses. 2. The parameters…

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
