Because i found that most of time it uses TKE1.5 and Smagorinsky SGS-TKE schemes which are commonly used in ideal case. But i'm confused when i saw that some geographycal data and boundary layer condition are used to run the outer domain (Mesoscale) before the LES after running ndown.exe. </font></div><div style="margin-top: 0px; margin-bottom: 0px;" id="yui_3_16_0_ym19_1_1470961300861_56045" dir="ltr"><font size="3"><br></font></div><div style="margin-top: 0px; margin-bottom: 0px;" id="yui_3_16_0_ym19_1_1470961300861_56045" dir="ltr"><span style="font-size: medium;" id="yui_3_16_0_ym19_1_1470961300861_63761">ndown.exe is supposed to be run in real case but how is the connection with LES if LES is run only in ideal case?</span><font size="3"><br></font></div><div style="margin-top: 0px; margin-bottom: 0px;" id="yui_3_16_0_ym19_1_1470961300861_56045" dir="ltr"><span style="font-size: medium;"><br></span></div><div style="margin-top: 0px; margin-bottom: 0px;" id="yui_3_16_0_ym19_1_1470961300861_56045" dir="ltr"><font size="3" id="yui_3_16_0_ym19_1_1470961300861_56351">If somebody is an expert in such domain, please give me some references which can give me clear understanding about one-way nested mesoscale to LES.</font></div><div style="margin-top: 0px; margin-bottom: 0px;" dir="ltr" id="yui_3_16_0_ym19_1_1470961300861_56046"><font size="3" id="yui_3_16_0_ym19_1_1470961300861_56228">Wish to hearing from you all.</font></div><div style="margin-top: 0px; margin-bottom: 0px;" dir="ltr" id="yui_3_16_0_ym19_1_1470961300861_56046"><font size="3"><br></font></div><div style="margin-top: 0px; margin-bottom: 0px;" dir="ltr" id="yui_3_16_0_ym19_1_1470961300861_56046"><font size="3" id="yui_3_16_0_ym19_1_1470961300861_63762">Batebana</font></div></td></tr></tbody></table></div></body></html>
