problem with amean and aave

[Shailendra Rai]

Hello,
You can try
'set t 1'
'set x 1'
'set y 1'
'set z 1 17'
'd  aave(var,x=1,x=xdim,y=1,y=ydim)'
here var is the variable name of which you want to take area average and xdim and ydim is values of length of variable in x and y direction.

Shailendra.
