Hi all!
I do the analysis of flow over a building.
The inlet constant velocity at 30m/s.
My domain has size of 1000x1000x4000 m, and distance from inlet to building is 1000.
I use LES model to analysis with the turbulence properties at default (Synthetic Turbulence Generator)
........
After 30,000 of iterations using the Adaptive Time Method,
It showed me at console "time flow" = 1.49.....s
I wanna ask is it a "real time" flow?
And when I check the result: the velocity and also pressure on my building were balance.
But, how can after near 1.5 second, how can it make pressure on the building when it just came (30m x 1,5s).?
OR I got wrong about flow time?
Pls help me, thank so much
