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.
