Is it possible to get run at the same time two lincenses of Plaxis3D with the same computer? or you need a computer for each lincense to run at the same time? Thank you !

Dear All I have modeled piled raft foundation which piles modeled as volume pile while raft modeled as plate element. To simulate soil - structure interaction, I created interface to both raft and piles. In my understanding, correct me if I'm wrong…

Hi, I'm making a base for a lattice mast in Plaxis 3D. The foundation takes the loads from the mast at four points. What is the best way to make bending moments Mx, My, Mz at all points?

Good morning. I have seen some people model a soil nailing problem using embedded beam with pile behavior and others with rock bolt behavior. In which cases should a soil nailing problem be modeled considering a pile behavior for embedded beams?

To perform a relibility based analysis of a 3D slope model, I have created a 3D FE-Model in Plaxis 3D and in the next step I would like to couple this with an external software that changes the soil parameters and starts the safty analysis in Plaxis.…

Hi All, I am working on the analysis job for an excavation work? So far I have proceeded to the completion of excavation that has been temporarily supported by struts? I am about to activate the ground floor level slab and deactivate the struts…

Hello, I am working on a simulation job for a excavation project. There is only one basement level, Bulk excavtion level is only about 3.2m below ground surface level, except that a local deeper excavation is conducted to accomodate the lift pit and…

Every time I am running the software this is showing. how to solve this issue ?

Hi ! I would like to ask, if I model a temporary deep excavation using plate elements with one row of temporary steel strut's with cap, should I increase the moment of inertia of the cap according to parallel axis theorem (Steiner)? Standard…

Which of the above analyses is better for finding the variation of excess pore pressure with radial distance from a line drain?

i am analysing the soil for moving load in plaxis 3d. each time after analysis load moves on the soil, but the movement is not that smooth and load seems like punching the soil.even on changing the soil properties this problem continues. also how to…

I have the following three questions about the input of the plate's unit weight. （1） If the groundwater level is -0.5m, the model has two layers of soil, the depth of the first layer is 1m, γunsat=17, γsat=18, and the depth of the second layer is 2m…

I installed a PVD (line drain) on MCC soil model and completed a consolidation analysis. In the output, the excess pore pressure at the drain is non-zero. I have used very fine mesh for this study, taking the smallest element as possible. How can I make…

I wanted to create a graph of excess pore pressure vs radial/horizontal distance for an MCC soil model at a particular depth installed with prefabricated vertical drains. To simulate the effect of smear, transition and undisturbed zones around the PVD…

As shown in the picture, I am simulating a suspended caisson, and I want to obtain a suspension force that will keep the caisson stationary at any depth. At present, my method is to add line displacement at the bottom of the caisson, but if I specify…

Hello, this regarding the true input of the modulus of elasticity "E" for an embedded beam element, either 2D or 3D. When using this feature for modelling a concrete structure (reinforced concrete piles, grouted nail...), it seems that there are doubts…

I am trying to simulate the effect of the installation of PVDs on soft soil (soil model used: MCC). The installation of PVD (in this case, a line drain) causes disturbance to the soil and creates three zones around the soil. A smear zone, a transition…

1. When I simulated the process of caisson excavation and subsidence, there would be a cycle process of excavation-sinking-excavation, which is embodied in plaxis3D as freezing the soil inside the caisson and changing the soil material at the position…

如果我想计算地面的沉降，出于某种原因，我必须在每个阶段结束时将位移重置为零。我想知道 Σ u_total 位移（重置）与最后阶段的总位移 u 之间是否存在相关性或相等性，而无需将位移重置为零。

Hi, there. I want to ask a question regarding piled-raft modelling in PLAXIS 3D. Currently, I am modelling the raft as a volume and the piles as embedded beam. As in the theory stated by Poulos (1994), the load-settlement curve of the piled-raft foundation…

Hello I need to know how I can define the distance between the Top and the bench in tunnel designer. lining and excavation also follow with 1-meter delay For example, I want to excavate the top 10 meters and then start bench excavation. I have…

I sent you many questions but I could not see my questions in the list of questions.
