WAsP-CFD in forest sites

[Gil]

Dear Team,

i am doing resource assessments in forest site with multi-masts mainly based on WAsP.  Western and southern parts of the site have a steep slope > 16.7 degree, so that I ordered WAsP-CFD. i read most of forest issues in this forum and also from webpage: https://www.wasp.dk/software/wasp-cfd/flow-model to understand better of WAsP-CFD.

However I still did not fully understand. I have some questions below. 

(Question 1) Are there any benefit of WAsP-CFD focusing on forest area? based on webpage above, it seems to me that WAsP-CFD use/interpret roughness data differently.

(Question 2) if WAsP-CFD has zero benefit compared to WAsP in terms of forest, should I apply same displacement heights in WAsP-CFD that were applied to WAsP?

(Question 3) based on WAsP, three main inputs are oro + rou + obs. How are obstacles dealt with in WAsP-CFD if they are not a part of input before run?

My last WAsP course was long time ago and i have used 3rd party CFD tools to handle forest. i think that could be the reason why I am still confused to understand how WAsP-CFD works. Could you please advise/guide me with details?

Thanks

still no answers? it seems like the forest has not considered at all but it would be great if expert(s) could explain this clearly because it could not find many information on the internet.
