Problem description

In the above mentioned versions, the Custom level water condition for the InitialPhase on a loaded project may be reset to Global when switching from Green (mesh/flow conditions/ staged construction) to Blue modes (soil/structures) and back again.

The water conditions will be reset to “Global” condition for this option. This issue only happens for the “Custom level” option condition after (re)loading the Plaxis file if the cluster’s water condition is set to Custom waterlevel for the InitialPhase.

Solution

This issue is now solved in PLAXIS 2D 2016.

In order to avoid this issue in PLAXIS 2D 2015 or earlier, you could use as an alternative the "Head" option instead of this “Custom level” option by specifying a reference head level. In this case, the pore pressures will be generated according to the specified head.

The model water conditions for all phases can be reviewed with:

• Individual check of the Water Conditions in the selection explorer for each polygon;
• Visualization of Water Conditions for all polygons in Flow conditions mode: the Custom waterlevel setting is visualized in a slightly lighter blue:
• the use of the echo command for the polygon of interest, for example:

   echo BoreholePolygon_1_1.Soil.WaterConditions.Conditions echo Polygon_1_1.Soil.WaterConditions.Conditions

• the use of the tabulate command for the polygon of interest, for example:

   tabulate SoilPolygons "Soil.WaterConditions.Conditions" tabulate Polygons "Soil.WaterConditions.Conditions"
