  • Reduction of soil suction limit (Psiunsat) leads to slower groundwater flow in unsaturated slope

    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…

  • How do i model footing to measure the bearing capacity and consolidation using PLAXIS 3D 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…
  • Plaxis 2D - Error Code: 101 - Failure After Excavation Base

    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…
  • Hydraulic discontinuity during flow analysis

    Good morning, I'm trying to define the global stability of an embankment supported by a gravity wall. In this case, I would like to perform an analysis in which the water level must be divided into two segments: one behind the wall at a height equal to…
  • GWT for the trial trench excavation

    Hi all, When we model the trial trenches in Plaxis (to find the utilities inside the ground, so can't provide embedded depths), how to draw the GWT to get the full water effect? If I used the groundwater flow and the head pore water pressure provided…

  • Plaxis 2D LE Error Writing a solver input file

    Hello, I am trying to run 2D groundwater/stress modeling and I keep getting an "error writing a solver input file for model" error when I click Solve. I have never had this happen before and am not sure how to fix it.
  • Create water level in Plaxis 3D

    Good day everyone, I am modeling a water storage dam (dam composed of rockfill and a clay core) in PLAXIS 3D for which I have already generated the model, however it is difficult for me to locate the water level of the dam, which corresponds to the…
  • Plotting Graph using Plaxis LE 2D Groundwater module

    Hi everyone, I am currently using Plaxis LE 2D, Groundwater module to run out a numerical simulation of transient seepage at levee. However, I am facing a small issue when generating the graph from the software. Does anyone here could kindly advise me…
  • Depth of groundwater table is unknown

    Hello everyone! I am trying to conduct the flow-deformation analysis for slope stability assessment under transient boundary conditions. However, the problem is that at the study site, we do not know the depth of the groundwater table. We are assuming…
  • Verifying the seepage face in Plaxis 2D in an unconfined groundwater flow
