Hello Erken,
If you want to use OPTION FOR WIND = 3, there are 2 possibilities:
- using an ASCII ATMOSPHERIC DATA FILE: in that case, you have to program something in Fortran as there are many ways to deal with your input file,
- using a BINARY ATMOSPHERIC DATA FILE: in that case, there is already a solution implemented in TELEMAC but your input file has to follow the expected format (see e.g. the WAQTEL user manual).
It would be strange to use the same file for options 2 and 3 as your file has only one value for every point.
hope this helps,
