I have a problem with the PLAXIS 3D model

Hi all:
I have a problem with the model, can someone please help me? Thank you.
I use PLAXIS 3D to create version elements to simulate continuous walls and buttresses (as shown in Figure 1). When I select buttresses and continuous walls for "intersect and recluster" (as shown in Figure 2), some version elements will only be represented by dotted lines ( As shown in Figure 3),

Hi all

when I use plaxis 3D to drew two vertical plates, , how can I make sure the plates is connected ?

About PLAXIS Calculation Optimizations

Sheng-Hsien Wang — Sat, 19 Sep 2020 14:57:57 GMT

hi sir:
I have several questions about the "SIG Workshop: Geotechnical Analysis – PLAXIS Calculation Optimizations" lesson.
The lesson shows: Stiffness changes are applied at the beginning of phase and unbalance is applied gradually during phase, change of stiffness without change of load has no effect.
My question is :
1.When I use a node-to-node anchor with prestress force at a phase, when the anchor element is applied? when the prestress force is applied? beginning of phase or applied gradually during phase?
2.When I numerical a deep excavation, the first phase is excavation (deactivate soil element ) and the second phase is to install the slab (use activate plate element with vertical deformation fixed) . when the slab (plate element) is applied? beginning of phase or applied gradually during phase?

thank you
