If you have a function (data table,...) providing the wind vector w =(wx, wy, wz) as a function of position and time, i.e. w (x,y,z,t), is it possible to make that work in FG, yes that is possible. | |||
Advanced Weather allows to specify a weather effect volume by function (like the distribution of lift inside thermals is implemented) and such a dedicated windshear function could be simulated close to the ground. The required tool is Nasal, FGs scripting language. | |||
There are other possibilities, you might for instance try to alter the generic boundary layer code of Advanced Weather to add automatic windshear detection, or you might alter the C++ code of Basic Weather - it really depends on what information you have and what you'd like to do. | |||
You probably want to have a look at the effect volume management routines. Basically you want to write something analogous to thermal_lift_start(), thermal_lift_stop() and thermal_lift_loop() in /Nasal/local_weather/local_weather.nas and use the management routines of effect_volume_loop() | You probably want to have a look at the effect volume management routines.
