Water Table Setting in FLAC2D 8.1

How can I define a fixed groundwater table for an embankment slope in FLAC2D 8.1?

First, go to Utility-> Table, create a table used for the groundwater table, and then go to Settings->GW, under Properties, and set the table ID for groundwater.

Thank you for your kind help! :smiling_face_with_three_hearts:
