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
CHECK 3520 - 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"
CHECK 3520 - 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 needs 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
Although TUFLOW automatically correct the face elevations, users can turn SGS Face Elevation Warning == ON (the default is "OFF") to report every faces with the issue to the _message_p layer. If the geometries input layers are all correctly set around these faces, turn SGS Face Elevation Warning == OFF to omit this warning message.
