6. PANEOLE FEATURES PANEOLE

7.  Roughness curves and altitude curves can be imported through map files  Mass consistent wind field model with Lagrangian multiplier technique and weighted interpolation schemes for one or more meteorological stations  According to the user specification, Cartesian or BFC grid generation techniques can be used for mesh generation  The influence of obstacles like buildings, hillocks on the wind pattern are considered  Turbulence models can be incorporated by selecting among the k-diff, k-l or k-eps models  Energy density with respect to the prevailing wind over the whole domain is calculated  Bar graphs show the power productions for the specified periods SALIENT FEATURES ….
