TUFLOW Message
CHECK 3520 - Found SGS cell face that has minimum Face elevation lower than the minimum cell centre elevations on both sides.
Alternate Message
Minimum U elevation must be higher than the minimum cell centre elevations on both sides in SGS. ZCmin left = "a", ZUmin = "b", ZCmin right = "c"
Minimum V elevation must be higher than the minimum cell centre elevations on both sides in SGS. ZCmin left = "a", ZUmin = "b", ZCmin right = "c"
Message Type
CHECK
Description
SGS model need to insure every cell face elevation is NOT lower than the minimum cell centre elevations on both sides. The warning suggest discontinuity in sub-grid elevation, which can happen occasionally during pre-processing of Sub-Grid Sampling. If this happens, the cell face elevation will be increased automatically to insure simulation stability.
Suggestions
Check in _message_p layer where this is happening and which Zpts command is causing this. If the input layers are all correctly set, you can also turn "SGS Face Elevation Warning == OFF" to omit this warning message.
