Parameter Theta s and theta b don't work

[hpd14thu]

I set theta s=5 and theta b=0.4 , these parameters should work on the spacing of near-surface.
But the value of s_rho shows that the grid is still equidistant.

I wonder how to solve this problems, look forward to your reply.

s_rho is not the final dimensional vertical coordinate. s_rho depends on the choice of TRANSFORM and the final z depths depend on the STRETCHING applied to s_rho.

There are Matlab and Python routines to compute z offline from the Vtransform, Vstretching choices and the parameters theta* etc.

Setting Hout(idpthR) == T in ocean.in will also write the time varying (because of zeta(t)) z coordinates to the history file.
