Velocity Validation

So I’m working on a project where i need to validate my software to see if it can give reasonably good results for along wind and across wind. I referred to a wind tunnel test that was done on velocity around several buildings and see whether i could get similar results. But i got very underestimated velocities from my simulation. I tried it on simscale and also Midas NFX. Both had similar results. I think i have made some error in my velocity input BC or somewhere else. Is there anyone who used midas NFX or simscale to achieve something similar? I wanna know what kind of velocity profile you need to input in an urban area

Hi there,
Welcome to SimScale and thank yo for posting on the forum!
Can you share your project link? We can take have a look
