v18 v19 19 19 == Summary of main features == 20 20 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. 23 24 * 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 avoid26 OBC restarts. May also code normal, and fully 2D Orlanski condition.27 * "Mercator-style" barotropic boundary conditions.28 25 * 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'' 29 34 30 35 * There will be two ways of specifying the boundary geometry:
