In 2D2010.01, the calculation kernel is now also capable of showing the direction and magnitude of the dissipation of excess pore pressures. When doing a such a consolidation analysis in classical mode (based on Excess Pore Pressures, EPP) in a combination with groundwater flow (steady state and transient), the results of the groundwater flow analysis will not be shown in the Output program, but instead the results of the excess pore pressure dissipation will be shown under the groundwater flow results.
Note that the results of the groundwater flow are still taken into account correctly for the deformation analysis, since the (classical) deformation analysis is controlled via the pore pressures and the effective stresses.
This has been fixed since PLAXIS 2D 2011.00
A possible work around in 2D 2010.01: Add an extra plastic phase which starts from the same phase as the Consolidation (EPP)-phase as a "dummy" phase for which the purpose is only to show the groundwater flow results. Make sure to set the same (transient) boundary conditions as in the Consolidation (EPP)-phase. The flow field shown for this "dummy" plastic phase will be the correct groundwater flow field for the Consolidation (EPP)-phase, too. You can use this flow field information together with the Output of the Consolidation (EPP)-phase to analyse results. Note that this solution is possible since you are calculating in the classical mode.
