WebMay 25, 2014 · There are some possible reasons you are getting pressure iteration failures: 1) the mesh aspect ratio is not good. Look at the ratio between cell size in Z and cell size in X: it should be <3:1 (big:small), otherwise the calculations are stretched and hard for the computer. The best ratio is 1:1 (squares). WebFeb 3, 2012 · In PLAXIS 3D, default boundary conditions are automatically applied: see PLAXIS 3D Reference Manual in the section about Standard Boundary Conditions. For e.g. soil volumes this means: Vertical model boundaries with their normal in x-direction (i.e. parallel to the yz-plane) are fixed in x-direction (u x = 0) and free in y- and z-direction.

Web1 day ago · When the default values of deformations and groundwater flow boundary conditions were used for the consolidation analysis, all the phases ran perfectly. But when I changed these conditions, since I needed the groundwater flow to take place through the drain alone and I needed to restrict the horizontal strain to zero, the phases failed and ...
