I am trying to simulate on dyson Design on simscale.
but I am facing problem. the basic idea is because of the shape dyson create pressure drop at leading edge, and because of that air get suck and we get the more mass flow rate. I have given link below can you help me to set boundary condition in simScale.

Hello @5a50c85d3c2040
I see this is your first ever post in our forum, so, welcome to SimScale’s community!!! 
This is a really interesting simulation you are trying to achieve here
I had a quick look in our public database and could already obtain a couple of similar projects that other users have simulated.
Check out this one
Its really similar to what you are trying to achieve !
You can also navigate through our public projects database to check what other users tried to simulate
Good luck with your simulations

Thank you !
