Showing velocity field function on curved surface

jraekim95 · March 5, 2021, 02:48

Hi,

I am trying to simulate how wind flows around the buildings over some terrains. And I created a 5m high surface along the terrain using the shell region. But somehow the velocity does not appear on the shell region I created.

Would you be able to tell me how to show the velocity on shell region?

(I tried iso-surface wall distance and threshold but shell surface created the best plane that I want to see).

Thank you!

I suppose because wall velocity is zero (unless specified otherwise). Try plotting Cell/Wall relative velocity. It should give the profile of the next cell.

Thank you for your reply.

I tried to plot relative velocity and figured out that I cannot plot any functions on the shell region that I created.

Could you tell me how to plot functions on the shell region?
