ANSYS CFX Fluidflow around 30x15x35 (LxWxH) in 26 metre height. Timescale per step: 2.5*10^-2 sec. Total steps 1500. Each frame is taken every 10 steps. The inlet boundary condition is a velocity profile: 1.45*25[m/s]*(z/10[m])^0.12 where z is the height.
Very nice!
Why the velocity profile for the inlet condition instead of a normal velocity? Would you still get vortex shedding along the broadside of the object with a constant inlet velocity?

@JamesUWA the velocity profile is taken from the DIN 1055-4.
It was part of the thesis to verify rules of this DIN.
I'm sure you would get the vortex shedding with a constant velocity too. The vortex shedding happens just at the begin of the simulation. After some seconds there is no vortex shedding anymore and the flow pattern is stable.

study the comprehensive ansys help. there are a lot of tutorials.
