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.

I think , you can do that using funkySetFields executable...
If you are not successful with that, see sonicFoam's setShock utility. You will get some idea in doing it

Hi!

Our Laboratory-made-utility setDiscreteFields would help you.

This utility can set profiles of any vector/scalar fields at specified boundary patches with using discrete profile data.

See setDiscreteFieldsDict in the attached archived file for details!

I know, that's a stupid question, but,
where do I have to put the setDiscreteFields to compile it correctly?

Hi, Ivan!

Any locations could be used for the proper compilation!

But I usually put source of this kind of non-standard utility
at $WM_PROJECT_USER_DIR/applications/utilities.

In this case the compilation commands would be described like:

$ cd $WM_PROJECT_USER_DIR/applications/utilities
$ tar zxf setDiscreteFields-1.0.tar.gz
$ cd setDiscreteFields
$ wmake
