[RegCNET] 1st, 2nd time deriv of ps = NaN

[Vincent Lanre Ajayi]

Dear all,
I am running RegCM3 for year 2000, everything was working fine initially until I got to April and it started displaying the following. I used prescribed dt =3*dx , my dx=25km and my dt =75.

Can anyone tell me what went work.
