| |
| − | <p> </p> You should set it up according to your application. The first question to ask is whether a "pure S" model is
| |
| − | sufficient for your problem. We found it's adequate for most problems (99.9%) except when strong stratification encounters
| |
| − | steep bottom slope (e.g., strongly stratified Columbia River plume flows over a shelf break
| |
| − | with slope in excess of 1/20). In the S part of vgrid.in, adjust the constants h_c, theta_b, theta_f to resolve appropriate
| |
| − | boundary layers. Note that h_c also determines the boundary between S-zone and sigma-zone (where traditional sigma-coordinates
| |
| − | are used becasue S-transformation is invalid when h < h_c).
| |
| − |
| |
| − | If (in the unlikely case that) a SZ model is needed, h_s may be chosen as the max. depth of the shelf, and make sure there is
| |
| − | a smooth transition between S and Z coordinates. You can get a preview of some sample z-coordinates at various depths
| |
| − | by running the code with the pre-processor flag (ipre in param.in) turned on.
