+ | ===== Simulation time ===== | ||
+ | The simulation time mainly depends on a) the model area size, more explicitly its number of grids in x,y and z and b) on the PC's hardware. Due to the non-linear nature of the microclimate and the many interactions between atmosphere, buildings, surfaces and vegetation, accurately simulating the microclimate is very computational heavy. | ||
+ | Especially large model areas benefit hugely from parallel processing i.e. the workload of simulating is distributed among all available cores of the model. So when ever you have the chance, you should enable multicore processing for the simulation. However, be aware, that for small model areas (less than 40 x 40 x 30 grids) single core processing might even be faster since the time needed to distribute the tasks to different cores might overcome the benefits of more cores working. | ||
+ | |||
+ | |||
+ | Either way, simulation time strongly depends on the hardware, the simulation settings (e.g. pollutant simulations with active chemistry take longer than standard simulations), | ||
