Wind speed input data in the LES model

[HEROISCOMING1]

Hi~~
When setting an area with a z grid of 2m, if the wind speed is input as follows, I understand that the input value is applied at an altitude of 2m and calculated by the wind speed profile equation above it, and I want to check whether I think it is correct.

"&WIND SPEED=10, DIRECTION=90, Z_0=1.0, L=-350. /"

Thank you~!

We recently changed the default reference height to 10 m. To be on the safe side, specify Z_REF explicitly. Then use the POINTS feature of a DEVC to produce a vertical profile of `QUANTITY='VELOCITY``.

Thank you for your answer.

I'm a beginner in fds, so I'm lacking a lot.
If so, can I write "&WIND SPEED=10, DIRECTION=90, Z_0=1.0, L=-350, Z_REF=00. /" to specify the location where the wind speed is input?

[mcgratta]

Z_REF=00.

What is the meaning of this? Do you want the wind speed to be 10 m/s right at the ground?

[HEROISCOMING1]

I would enter the altitude I wanted in place of '00'.
For example, if the wind speed is 10m/s in the model area of ​​25m,
I tried to write "&WIND SPEED=10, DIRECTION=90, Z_0=1.0, L=-350, Z_REF=25. /".
Is this correct?

[mcgratta]

You mean to say a height of 25 m. Yes, this is correct.
