TUFLOW Message
ERROR 3201: Error in U face proxy: face <id>, proxy face = <id>, proxy cells <id> and <id> not within the same sub-subdomain
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 maximum limit for equivalent mannings number is required as the formulation becomes singular at shallow depths.
This limit, provided as the fixed mannings n value in the material data, must be greater than zero.
Suggestions
Ensure that all materials that utilise log-law roughness have positive values for mannings n.
