Yes, the units for the bottom and surface boundary conditions do not match. The boundary conditions can be computed in different ways. This corrected by a linear extrapolation.

  • Ticket #95 – Description

    initial v1  
    1 wvelocity.F, near the bottom we have:
    2 
     1'''wvelocity.F''', near the bottom we have:
     2{{{
    33          wvel(i,j,0)=cff1*(vert(i,j,1)-
    44     &                      (vert(i,j,2)-vert(i,j,1))*
    … …  
    66     &                cff2*vert(i,j,1)-
    77     &                cff3*vert(i,j,2)
     8}}}

    9 written out this is:
     10'''cff1''', '''cff2''', and '''cff3''' are coefficients for the interpolation (just numbers). '''vert''' has dimensions of m/s.  So this is:
     11{{{
     12( m/s - ( m/s - m/s)* 2 * (m))   +   m/s  +   m/s
     13}}}
     14This does not look dimensionally correct. Same issue for '''wvel(i,j,N)'''.

    11 wvel(i,j,0)=cff1*
    12 (vert(i,j,1)-(vert(i,j,2)-vert(i,j,1))*2.0_r8*(z_r(i,j,1)-z_w(i,j,0)))+
    13 cff2*vert(i,j,1)-cff3*vert(i,j,2)
    14 
    15 cff1, cff2, and cff3 are coefficients for the interpolation (just numbers).
    16 vert has dimensions of m/s.  so this is:
    17 
    18 ( m/s - ( m/s - m/s)* 2 * (m))   +   m/s  +   m/s
    19 This does not look dimensionally correct.
    20 Same issue for wvel (N).
