Problem description

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.

Solution

The issue is now solved in PLAXIS 2D 2015.01

Unfortunately no solution exists for this issue in PLAXIS 2D 2015.00.
