For the hardening soil and hardening soil with small strain models, PLAXIS material models manual states that the Pref = 100 kPa in PLAXIS (and it is better to leave it at that) and also Pref = confining stress in a drained triaxial test. I am conducting…

Hi, I am creating materials using command line like this: _SOILMAT "Name" "Soilmat_Sand_1" "SoilModel" "Hardening Soil" "Identification" "5" "GAMMAUNSAT" 17.66 "GAMMASAT" 18.47 "EOEDREF" 10000.0 "E50Ref" 10000.0 "EURRef" 50000.0 "cRef" 10.0 "phi" 10…

Hello, I want to ask something about raft modelling. Can anyone explain how I can model a raft whose thickness changes along the x-axis (decreasing towards the edges) ? In such a case, can I model the raft as a plate element?

Hello, After Initially successfully installing and launching both PLAXIS 2D and PLAXIS 3D, the program starts to crash upon opening and the following error pops up as well which states: DoBoot(): Failed To Initiliaze DLL Any Help Would Be Much Appreciated…

How to input permeability for smear zone around PVD in plaxis 2D v21?

Hello folks I am creating a gui-enabled script using Pyside2. My goal is to change the line length. The user will select the line to modify and enter the length. Selected_Line = self.Lines_QComboBox.currentText() #select the line Line_Length = float…

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…

I don't want to change the soil command. Efficiently enter commands in Excel.

Hello everyone I wonder about the meaning of the Maccel value. I checked the Plaxis 2D reference manual and it says "The value of this parameter is always 0." Why it's always zero and what does it do? Thank you

Hello, I have modeled a simply supported beam in Plaxis-2D and 3D, and by using a Poisson's ratio of zero the deflections are similar to theoretical values (and checked it vs. Abaqus). However, by considering a Poisson's ratio of 0.3 the displacements…

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…

Dear Guys, First of all I am new to this forum. I never knew such a forum existed. I am modelling a steel supported braced excavations (struts). In the project the diagonal struts in the corners are 20 metres long while the horizontal (located at…

Hi In rock, it is common to have a linearly varying in-situ stress (described by a slope + and INTERCEPT). Software like RS2 supports this kind of in-situ stress definition. Will PLAXIS support it as well? It would be really helpful. Thanks

I want to simulate a axially loaded pile (2d or 3d does not matter). Initially I want to apply only gravity. 1. I want extract a stress file (stress for every gauss point in every element). Is it possible? How do I extract it? 2. Modify the stresses externally…

Please help: Stiffness matrix is nearly singular and cannot be solved [error code: 20] in PLAXIS 3D. Can anyone help me to fix this file ? File Link: drive.google.com/.../view

Hi, I am running a sensitivity analysis for an excavation after demolition of an existing structure. The analysis includes a number of pile elements and plate elements. The pile locations are updated by sometimes a 0.5m or so. Now, with Plaxis Input…

Dear Support Team and PLAXIS users, Could you please suggest me webinars or scientific articles discussing/explaining cyclic loading application on soft ground in PLAXIS, especially in the case of onshore wind turbines. Thank you in advance. Kind regards…

Title: SIG Virtual Workshop: Geotechnical Analysis - Modelling Piles in PLAXIS Date/Time: December 18, 2020 at 10:00 A.M. CET and again at 04:00 P.M. CET Presenter: Micha van der Sloot, Senior Manager User Success - Geotechnical, Bentley Systems, Inc…

Is there anyway to fast preforming Sensitivity / Parametric Analysis in PLAXIS 3D similar to the option in PLAXIS 2D?

Hi there, I am looking for some guidance on the interpretation of stresses when tunnel lining is modelled as a solid element. Plaxis manual suggests that the largest compression is Sigma 1 whereas the largest tension is Sigma 3. If I am looking to find…

Hi, I made attempts to submit some technical questions to the Plaxis support, and it directed me to the Bentley Connect Centre-Service Request Manager, where I was confused that I do not know what product category Plaxis belongs to. Anyways I filled…

Hi people, I have a question of the installation process of the suction caisson (pile) foundation of offshore wind turbine. Since I already review the tutorial of “Loading of a suction Pile”, I’m wondering if I can use Plaxis 3D model to create a procedure…

We wanted to know if PLAXIS can model a concrete diaphragm quay wall (wharf) structure. The wharf consists of concrete diaphragm wall on waterside against which the ships dock) and landside and a series of vertical concrete elements called barrettes …

If I want to delete the second points of the selected line, the command line would be: del line_1.second If I want to apply the same command to a list of lines, how is it possible? would it be something like this? group_1 is a list of lines. map…

Hi, I am wondering how it would be possible to analyse stress/strain relaxation in the CRS soil-test-facility in PLAXIS 3D? I am currently using the Soft soil creep model and used the optimise parameter function to match with the lab data. However…
