hi,
I am doing a simulation,it is about the wind pressure on the building.there is a problem to set the velocity of the wind.It is ok to set the velocity by a exactly value,such as 5m/s,8m/s.but the fact is the velocity of wind is change by the height,such as 0.2Z(Z is the height of the building.)and I don't know how to fix it. I am very appreciate if someone can help me.thanks.and I am doing the simulation in turbFoam, |

You have some options for this situation:
1. Write your own utility 2. Use funkySetFields (is this possible?) 3. Modify the setParabolicInlet utility to give a linear variation in velocity with increasing height. Please search the forum for posts on funkySetFields and the parabolic inlet. |
