My constant wind-induced case seems strange

[zhangtianhao]

I set a closed boundary pool(50m*50m), △x=1m, △t=0.2s.

There is just one forcing condition, a constant Uwind = 8m/s.

But my result looks so strange. (I think it should be a smooth parabola)

Here is my result.png. It looks unnatural.

The x-coordinate is u(m/s) ,and the y-coordinate is s_rho. I just want to draw the relationship between the velocity of flow and the water depth under the condition

of a constant Uwind.

!
! Each tracer variable requires [1:4,1:NAT+NPT,Ngrids] values. Otherwise,

! order is: 1=west, 2=south, 3=east, and 4=north. That is, anticlockwise

!
! The keyword is case insensitive and usually has three characters. However,
! it is possible to have compound keywords, if applicable. For example, the
! keyword "RadNud" implies radiation boundary condition with nudging. This
! combination is usually used in active/passive radiation conditions.

I think the result should be like this:
( I draw this picture by the analytical formula)

[jcwarner]

THETA_S == 8.0d0 ! surface stretching parameter
THETA_B == 0.5d0 ! bottom stretching parameter
TCLINE == 20.0d0 ! critical depth (m)

use something like Gout=get_roms_grid('ocean_his.nc',tidx);
this will give you a field Gout.s_rho that you can avg to get the vertical locations of your grid. how did you get the 'z' values in your plot?

Ok, then i saw your bc's and it says everything is closed. Try to do a periodic in N-S or E-W.

Thank you for your suggestion! By the way, I have another question, I try another case, a hurricane-induced flow field (set a hurricane on the centre of a square field). If I just do a periodic N-S or W-E, the field will be asymmetric. But if I do a periodic N-S-W-E, it seems strange...
