Blowing up!

#1 Post by liangliang » Wed Jul 24, 2013 6:14 am

I try to couple ROMS with swan .But when i run it ,it is blowing up !
I find that :
Maximum grid stiffness ratios: rx0 = 6.666667E-01 (Beckmann and Haidvogel)
rx1 = 1.262620E+01 (Haney)
Does that mean i should smooth my grid ?

My grid is wrong . I change it ,and reduce time step . It is OK !
