An issue is unfortunately introduced in PLAXIS 2D 2015.00 which causes the boundary conditions of inactive dry clusters to be incorrectly set. As a result of this issue a groundwater flow (both steady state and transient) may converge to a wrong solution. In general, when inspecting the output results (such as: flow field plot, psteady, pactive, etc.) this will become clear.
The issue is now solved in PLAXIS 2D 2015.01
Unfortunately no solution exists for this issue in PLAXIS 2D 2015.00.
