TUFLOW Message
ERROR 3026: kappa must be >= 0.
Alternate Message
NA
Message Type
ERROR
Description
Materials may use use either fixed mannings, depth-varying mannings, or log-law roughness formulations for bed resistance.
When utilising log-law roughness, a value for kappa of less than zero is not permitted.
kappa is typically in the range 0.38 to 0.42 (recommend 0.4).
Suggestions
Ensure that all materials that utilise log-law roughness have positive values for kappa.
