    v18 v19  
    1919== Summary of main features == 
    2020 
    21  * The following algorithms will be included in the first implementation: 
    22    * Clamped and Flow Relaxation Scheme. (Clamped is FRS with rimwidth=1). 
     21 * The following algorithms will be definitely be included in the first implementation: 
     22   * Clamped and Flow Relaxation Scheme for all variables. (Clamped is FRS with rimwidth=1). 
     23   * Zero gradient condition for all variables.  
    2324   * Flather radiation condition on barotropic solution. 
    24    * NPO version of Orlanski radiation condition as currently included in OBC. 
    25      Plan to code ''implicit'' time-stepping for greater stability and to avoid 
    26      OBC restarts. May also code normal, and fully 2D Orlanski condition. 
    27    * "Mercator-style" barotropic boundary conditions. 
    2825   * Tidal harmonic forcing (included in Flather boundary condition). 
     26   * Orlanski radiation condition with normal projection of oblique radiative velocities (NPO) 
     27     for T and S, 3D and 2D velocities. Plan to code ''implicit'' time-stepping for greater stability and to avoid 
     28     OBC restarts (''Marchesiello et al 2001'').  
     29   * sponge layer (enhanced viscosity near the boundary) 
     30 
     31 * The following algorithms may be included: 
     32   * Orlanski radiation condition with normal velocities and fully 2D velocities. 
     33   * Other conditions on barotropic solution from ''Chapman 1985'' 
    2934 
    3035 * There will be two ways of specifying the boundary geometry:
