Hi. Can someone explain me why we should not model the length direction of a strip foundation when settlement analysis?

Hi all, I was modelling the volume expansion (due to temperature change) by inputting the volume strain of material directly. But when I consider the tunnel, I cannot input the volume strain value to the lining ( plate material), so it shows the wrong…

Hi all, I am modelling the energy pile behaviours under different thermal operations ( by setting the different thermal boundary conditions to pile boundaries to see the temperature-induced volume change of pile and soil). For the initial installation…

Hello everyone, I'm trying to simulate the installation of shaft sinking by adopted procedure from kinematic mechanical model, but I'm struggle with the skin friction at the wall of shaft. Can I assign the value of skin friction directly in the surface…

I am using the precipitation function to model rainwater infiltration on a slope in PLAXIS. When inputting the q value, do I need to multiply the rainfall (q) with the runoff coefficient (c) first?

Hello, I was simulating the slope under the dynamic condition to assess the displacement under dynamic loading, during the calculation phase the curve shows there is variation in displacement with time but when it appears in the graph, that shows up a…

I’m a newer user to PLAXIS 2D Ultimate and I am trying to work through a few modeling errors. The problem I am solving is that I’d like to assess the deformation of a dam for which liquefaction occurs within the foundation soils to understand whether…

Dear I modeled a real point cloud data in to the Plaxis 3D FEM and the data comes from the real survey of an investigation. In this regard, it is obvious that we have a complex surface from the real data. In this analyze, we want to investigate the…

Hi, I want to set automatic values in the legend for OUTPUT using Plaxis Python. I tried this: g_o.Plots[- 1 ].LegendSettings.MinValue.Automatic = True g_o.Plots[- 1 ].LegendSettings.MaxValue.Automatic = True it doesn't give any error, but also…

Dear I am modelling the rainfall in a specific area in the Plaxis 3D FEM and defined the polygon to determine the rainfall in that area. The specification I used in different phases are as follow: Initial phase: Calculation type: Flow only Pore…

Hi Everyone, Thanks for the help in advance!! I understand the plastic failure point means the soil element is currently at the failure envelop and it could disappear in the next calculation step if unloading occurred. However, I figured there…

I have modelled Deep Mix Column under embankment loading. In this modelling, I have made a negative interface around the DM column and assigned property custom [ DM Col-MC model_Drained_E_v_c_phi-r inter-0.69]. When I hit calculate button in stage…

Hi everyone, Thank you in advance for helping out. I understand that the incremental displacement by default is the displacement at the last step of the current calculation phase. My question is how to get the displacement value for each calculation…

In PLAXIS V20,V21 and V22 there is included PVD drain. But How can I simulate Stone column in PLAXIS 2D v21 ?

Hello. I am new to PLAXIS 3d V21. I have been learning PLAXIS 3D V20 which seemed to be much simpler than the current V21. I wanted to design a shallow footing setting on the ground surface. I want to measure the bearing capacity of the ground and…

Dear sir, I have a query in plaxis 2d. 1. Why should we assign interfaces ( Positive and Negative) to the plate element in plaxis 2d? 2. What is purpose of assigning the interface? 3.But in Plaxis 3d, we will not assigning any interfaces to the…

Hello Everyone, I know in PLAXIS , when we do an earthquake analysis we define interface boundaries along the side and bottom boundaries . IF I do the same in PLAXIS #D, should I do the same, Please advise. Thanks , Faisal

Hello, I want to reduce the height of my model by using a line load (right) instead of modeling the hole height above the tunnel (right) like shown in the following picture. - ground water isn't considered in this model, so no pore pressure - K0…

Is there a way to implement a SWRC with parameters determined with SWRC Fit (free online software) to the parameter values ​​that Plaxis uses? Or is there a way to be able to directly enter measured values,suction and volumetric water content, ​​into…

Hi, I have to draw 2 slope stability model, where FS have to be 1, one models cohesion and friction angle have to back calculate from a failure, for the other model how can I get again FS 1 with different cohesion and friction angle? the geometry will…

Hi, PLAXIS team, I'm struggling to understand what the upper limit for material stiffness, i.e. E50 in Hardening Soil Model is? I am exploring different material models for a very low to low strength Siltstone (UCS = 1MPa, E50 = 300MPa) and I was thinking…

Plaxis analysis for footing on compacted sandy soil (subexcavation and backfill to increase bearing capacity) overlying loose sand. Soil Collapse occurs way before real failure. All options (fine mesh, interfaces between different materials, various…

Hi, I need to model a bored pile wall with shotcrete between the piles and a pile head cap in Plaxis 2D ultimate. Am I better to model this as an equivalent plate element using the effective stiffness per meter length or as an embedded beam row? Thank…

Hello All, I have a question about the hardening soil model. In PLAXIS we have HS and HSsmall for modeling soil behavior. In HSsmall, there is a parameter gamaa_07 to incorporate dynamic behavior which is not included in HS. Also, in the materials…
