== Test Case 2 - Discussion==
The urban modellingmodel resultstesting indicateindicates result convergence occurs when the cell resolution is observedless forthan all20ft. casesThis observation agrees with the ARR guideline recommendation for urban models to use a cell resolution less than 20ft.of
2m (6.6ft) to 5m (16.4ft). <br>

As per Test Case 1, selection of the appropriate cell resolution during a real-world project requires consideration of the intended use of the results and also how the simulation times impact on the overall project timeline.
