| 74 | !! ** Purpose : Compute the now trend due to the surface pressure |
|---|
| 75 | !! gradient in case of filtered free surface formulation and add |
|---|
| 76 | !! it to the general trend of momentum equation. |
|---|
| 77 | !! |
|---|
| 78 | !! ** Method : Filtered free surface formulation. The surface |
|---|
| 79 | !! pressure gradient is given by: |
|---|
| [1601] | 80 | !! spgu = 1/rau0 d/dx(ps) = 1/e1u di( sshn + btda ) |
|---|
| 81 | !! spgv = 1/rau0 d/dy(ps) = 1/e2v dj( sshn + btda ) |
|---|
| [358] | 82 | !! where sshn is the free surface elevation and btda is the after |
|---|
| [1438] | 83 | !! time derivative of the free surface elevation |
|---|
| 84 | !! -1- evaluate the surface presure trend (including the addi- |
|---|
| [358] | 85 | !! tional force) in three steps: |
|---|
| 86 | !! a- compute the right hand side of the elliptic equation: |
|---|
| 87 | !! gcb = 1/(e1t e2t) [ di(e2u spgu) + dj(e1v spgv) ] |
|---|
| 88 | !! where (spgu,spgv) are given by: |
|---|
| 89 | !! spgu = vertical sum[ e3u (ub+ 2 rdt ua ) ] |
|---|
| [2000] | 90 | !! - grav 2 rdt hu /e1u di[sshn + (emp-rnf)] |
|---|
| [358] | 91 | !! spgv = vertical sum[ e3v (vb+ 2 rdt va) ] |
|---|
| [2000] | 92 | !! - grav 2 rdt hv /e2v dj[sshn + (emp-rnf)] |
|---|
| [358] | 93 | !! and define the first guess from previous computation : |
|---|
| 94 | !! zbtd = btda |
|---|
| 95 | !! btda = 2 zbtd - btdb |
|---|
| 96 | !! btdb = zbtd |
|---|
| 97 | !! b- compute the relative accuracy to be reached by the |
|---|
| 98 | !! iterative solver |
|---|
| 99 | !! c- apply the solver by a call to sol... routine |
|---|
| [1438] | 100 | !! -2- compute and add the free surface pressure gradient inclu- |
|---|
| [358] | 101 | !! ding the additional force used to stabilize the equation. |
|---|
| 102 | !! |
