TUFLOW Message 2306
ERROR 2306 - WrF value must be greater than zero.
Occurs when a WrF (Weir calibration factor for upstream controlled weir flow) of zero has been found. For Wetting and Drying == ON Method B which has been the default method since 2012-05 a non zero WrF must be specified. For Wetting and Drying == ON or Defaults == Pre 2012 a zero value could be used to locally turn off the weir function.
Check for zero values that may have been inadvertently applied using one or a combination of the following commands: Read GIS WrF ==, Set WrF ==, Read RowCol WrF ==.
