Hello everyone I am using Phoenics for studying wind environment in downtown area,
Could you please tell me which Turbulence model is better for evaluation of wind environment in downtown area?
I try to use the KEMMK in KE Variants, is that ok?
but i found it looks the same as KEMODL according the the constants in both of them,

also can i change the roughness parameter in the setting of this RANS model, i want to change it to 0.27 the same as i did in wind tunnel experiments.

Thank you very much for your help
