\noindent\textbf{Simple examples:} For a model grid with $ N_{x}\times |
| 272 |
|
N_{y} = 120\times144$ horizontal grid points with four open boundaries |
| 273 |
|
along the four egdes of the domain, the simplest way of specifying the |
| 274 |
|
boundary points in \code{data.obcs} is: |
| 275 |
|
\begin{verbatim} |
| 276 |
|
OB_Ieast = 144*-1, |
| 277 |
|
# or OB_Ieast = 144*120, |
| 278 |
|
OB_Iwest = 144*1, |
| 279 |
|
OB_Jnorth = 120*-1, |
| 280 |
|
# or OB_Jnorth = 120*144, |
| 281 |
|
OB_Jsouth = 120*1, |
| 282 |
|
\end{verbatim} |
| 283 |
|
If only the first $50$ grid points of the southern boundary are |
| 284 |
|
boundary points: |
| 285 |
|
\begin{verbatim} |
| 286 |
|
OB_Jsouth(1:50) = 50*1, |
| 287 |
|
\end{verbatim} |
