I am trying to use the "if else" statement to set the lower limit of negative values.
However, the script below is not working. u_ave_1 still has the value below -20. It's supposed to work and had worked before. I don't quite understand why.
let u_ave_1 = if u_ave[d=1] lt (-20) then (-20) else u_ave[d=1]
Thanks in advance for your help!
