TUFLOW Message 2080
ERROR 2080 - Bed Resistance Cell Sides == INTERROGATE must be used with Inside Region == Method B
Bed Resistance Cell Sides == INTERROGATE (.tcf) must be used with Inside Region == Method B (.tcf). Both of these are defaults. TUFLOW inspects the bed resitance from GIS layers (Read GIS Mat). The approach for Bed Resistance prior to 2007-07 was average M. Valid options for Bed Resistance Cell Sides == AVERAGE M or AVERAGE n or MAXIMUM n or INTERROGATE
This error should only occur if the default Inside Region == Method B is overwritten, Method B is vastly quicker the Method A and testing shows identical results.
