TUFLOW 2D Cell Size Selection: Difference between revisions

This page of the TUFLOW Wiki discusses 2D cell size convergence. In well designdesigned modelling software such as TUFLOW, cell size convergence refers to the tendency for model results to trend towards a common answer as cell size decreases. This behaviour occurs due to topographic features that influence the hydraulic flow behaviour better approximating reality as resolution increases. The series of creek cross-section images below demonstrate this. As model resolution increases from 20m to 5m the modelled topography progressively matches the real-world geometry more closely.<br>
