1.00E-08.

Modified Contents

• When the water table lies above the ground surface (e.g. dams) or if it lies outside the model (e.g. flooded

excavation), a line pressure corresponding to the water lying outside the model is added automatically along

the model boundary to equilibrate the volume pressure load.

in stress analysis. Unlike V300, there is no need to set a separate function for the ground water level water

in stress analysis to account for seepage analysis results. V1.1 also supports transient Seepage-Stress

coupled analysis. Pore water pressure generated from seepage analysis automatically transfers into stress

analysis.
