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…

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…

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…

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…

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…

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, 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

Hi all, I'm trying to deep excavation in Plaxis2D. But in some phases I get error code:101 warning. This collapse does not happen when I go down to the excavation base level, but when I define the foundation slab (node-to-node anchor) located at the…

I give -20 kN/m (point load) on my shallow foundation but when i calculate it. there is no any Fy apllied to my project ps. I activate oint load already Thank you

I know Python can be used for the newer versions. Is there any way to automate the modeling, settings, and calculation process for Plaxis 8.6?

Hello. I want to ask about error code 34. I'm currently modeling soil improvement using vacuum consolidation, but when I'm calculating error code 34, how do I solve the error regarding the ultimate state not reached in groundwater flow analysis?

Hello. I want to ask about the column diameter equation from Axisymmetric model to Plan strain model, is it in plaxis or is there any geotechnical expert who recommends a special formula to convert the equivalent diameter from Axisymmetric model to Plan…

Hello mr & mrs. I want to ask about how to find out the distribution of earth stress due to embankment load on Plaxis 2D? I am planning to install a PVD, where the regulations in my country recommend that the PVD must be installed at a depth of soil that…

I want to ask when reviewing soil improvement using PVD, why is the result of the decrease in time using my plaxis 2D when 2 m spacing is faster than 1.5 m spacing and 1.5 m spacing is faster than 1 m spacing?shouldn't pvd spaced closer should be faster…

Hello everybody I perform seismic analysis in Plaxis 2D model by using a harmonic signal (0.11 g, 1 Hz). I set horizontally fixed lateral boundaries and used absorbent boundaries in dynamic analysis (free field for boundaryX and compliant for boundaryY…

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

Hi I have been looking at a model in Plaxis3D for a shallow footing overturning under an applied shear and moment. When i look at the results for the interface element at the base for normal pressure, it shows the front of the footing in compression…

Hi, My geotech team is using PLAXIS 2D to predict the settlement from 100-ft deep soft soil. During our check on input parameters, we found that the Poisson's Ratio for Unloading and Reloading (Vur) considerably affected the settlement amount in soft…

I am aiming to simulate a deep excavation near an existing tower with 4 levels of below grade parking (shaded in grey). The approximate loading of the building is 10 ksf. Therefore I have simulated the material (shaded in grey) as a non-porous Mohr Coloumb…
