TUFLOW Message 2222
ERROR 2222 - Period attribute (eg. time taken for failure) must be greater than zero.
WARNING 2222 - Period attribute (eg. time taken for failure) is very short.
The period attribute in a variable z shape layer (2d_vzsh) defines the time in hours over which the variation in Zpt elevations occurs. This must be greater than zero. From 2020-01-AB warning is issued if Period attribute is greater than zero, but below 0.01hr. Previously Period under 0.001hr was recognised as zero and error was issued.
Set a valid period in the GIS layer and/or check the very short period is intentional.
