algorithmic modeling for Rhino

Wind Speed is too Low, when calculating the outdoor_airflow using butterfly.

hi,

I ran the example file "01_0_outdoor_airflow.gh" in the "butterfly0004" folder which was downloaded from the plugin page.

I tried to run this case by click the following buttons :

WIND TUNNEL-->run

BlockMesh-->run

snappyHexMeshDict-->snap

snappyHexMesh-->run

solution-->write

solution-->run

But during the calculation, I got the wind speed lower and lower. After 10 iterations, it became too low to be observed.

 

I didn't modify any other parameters. Can anyone know how I can solve this and get the proper result?

Sincerely,

panyuqing
