+ | ===== Purpose ===== | ||
+ | The model offers the possibility to change different timing settings for processes that are not calculated for each time step.\\ | ||
+ | You should not use larger intervals than the default values. | ||
+ | |||
+ | **ENVI-met will check the time steps and give error messages if problems exists. These errors must be taken seriously.** | ||

+ | |||
+ | === 01: Update Surface Data (Default 30.0 s)=== | ||
+ | Re-calculation of surface temperature and humidity. | ||
+ | |||
+ | === 02: Update Wind and Turbulence (Default: 900 s)=== | ||
+ | Interval for updating the flow field and the turbulence data (kinetic energy and the exchange coefficient) in the atmosphere.\\ | ||
+ | Turbulence is only updated, if turbulence mode " | ||
+ | |||
+ | === Continuous wind calculation NEW === | ||
+ | You can also choose to calculate the wind field for each time step.\\ | ||
+ | To do this, set update interval to " | ||
+ | However, this will require very small time steps for the flow field and makes the simulation very slow.\\ | ||
+ | This is a test option to make a tribute to high-end computers from your local supermarket. Not really tested, but should work. | ||
+ | |||
+ | === 03: Update Radiation and Shadows (Default: 600 s) === | ||
+ | Update of the sun position, the shadows and the radiative fluxes from the sky. | ||
+ | |||
+ | === 04: Update Plant Data (Default: 600 s) === | ||
+ | Recalculation of leaf temperature, | ||
