Hi WAsP Team.
As you can see in https://www.wasp.dk/waspcfd/flow-model in section "Preparing the height countor map":
"..., the CFD model uses a fixed domain size (radius of 15 km) and grid resolution (grid size of 20 m) irrespectively of the digital map.""
"The zooming grid of the IBZ model as well as the CFD model indicates that the countor line description close (within 2km or so) to the prospected site(s) should be as detailed and accurate as possible (countor separation of less than 10 m)...."
I would like to understand if WAsP CFD have a limit to "accurate as possible" in terms of height contour lines discretisation. Like 30 cm, 1 m, 5 m or less than this... And if I use the less one, my result gonna be better?
Thank you.
