This estimation also does not account for 1D computational time. In the majority of cases the 2D computational load is far greater than the 1D, and as such, is typically the dominant factor that influences the overall simulation runtime. The proportion of simulation time spent on the 1D and 2D hydraulic calculations, and also other tasks, can be reviewed via the [https://docs.tuflow.com/classic-hpc/manual/2023-03/Checks-and-Logs-1.html#run-stats-3 _run_stats.txt] log file.

The spreadsheets linked below can be used to estimate TUFLOW simulation times based on the cell size, catchment area and simulation time (i.e. event duration). The runtime depends on a number of factors such as the speed of the CPU and also the fraction of the model that is wet. The more wet cells the more calculations that are required and therefore the slower the simulation. <br>
