[RegCNET]Re: Problem using NNPR2

[moetasim]

If it slows down and gives nan nan then there must be some problem with ICBCs. Can you check 
them before running regcm. And if you find problem in ICBC then check your NNRP window!

BTW, does it give same problem no matter what is the date of your experiment with NNRP window?
