Hi Josh,

Thanks for posting the link on polyhedral advantages. It was quite useful.

Anyway in my control volume, there are 2 buildings - one directly behind another. Each building is 20m by...

Ar.. thanks for helping out with the Turbulence Intenity. :)

Anyway I previously said that my velocity magnitude monitors "flattened" out when I ran the solution as unsteady, but it seems that it...

Hi Josh,

Thanks for the help. It seems that my solution converges after the first run as unsteady (my velocity magnitude monitors flattened out), although time time step was small and my inner...

Indeed, it did look like von Karman vortex developing behind the building. Thanks for pointing that out!

I did try running the simulation in implicit unsteady state, but I'm not sure if I was...

Hi Josh,

I've read several times that residuals are not good indicators of solution convergence. Hence, I have set up 3 velocity magnitude monitors behind my buildings to see if the velocity has...

Help with Wind Flow Across Buildings

Hi guys,

I'm trying to do some very simple simulation of wind blowing against some buildings (4 square buildings, set in a square, to be precise).

In my simulation, I noticed that at Z=0...
