How to extend LES domain?
Whiffle Wind automatically suggests an LES domain based on your turbine and met mast positions, as described in Step 2 of Under the Hood. However, there may be cases that require manual extension of the LES domain, e.g. to include additional areas such as nearby mountains or landmasses.
On the Layout step we provide the possibility to customize the domain, by simply clicking the "Extend LES Domain" button.
You will then switch to drawing mode, in which you can draw a (rectangular) additional area of interest on the map. The automatically suggested LES domain will be extended instantly to incorporate the additional area.
Manual extension of the LES domain is at the user's own discretion. Please be advised to revise our best practices below and contact Whiffle Support when in doubt.
Best practices
Including a neigbouring landmass
To include an additional landmass or geographical feature close to your landmass, we recommend to draw the additional area only around the geographical feature. This will provide the optimal LES domain based on the additional area and turbines.
Horizontal extrapolation
To enlarge the LES domain in all directions, for example when defining an area for horizontal extrapolation, it is possible to draw the additional area around the LES domain.
