Hi,
I tried many things suggested by you but still I am at the same level.
Below is the output of my screen:

name : wind
app : wind appClass 7
fatal:Number of dimensions in parameter (2) of (wrf_vector) is (3), (2)
dimensions were expected
fatal:["Execute.c":8640]:Execute: Error occurred at or near line 60 in file
Zwind.ncl
What I feel, the way as I fixed the pressure level is not working properly.
Kindly see my script (and) or give me any idea how can I plot U,V wind at
some 850 hPa obtained from WRF model output.
