Creating Save Points
Save points are cell-specific output that is used for CMS-FLOW simulations. To create save points do one of the following:
- Create Save Points from an existing CMS_FLOW grid.
- Click on the Select Grid Cell tool on the active grid.
- Right click on one or more selected cells and select Add Save Point(s)...
The CMS Save Point Manager is displayed showing the new cell(s). If no save points existed prior to this, a new save point coverage is created and a link will appear under the grid in the tree item data.
– OR –
- Right click on Map Data and select New Coverage. Find CMS-Flow Save Points under CMS-FLOW and click "Ok". A new save point coverage is created. Click on the new coverage so its active, then click the Create Feature Point tool. Click out some feature points. When finished, right click on the new coverage and select Properties. The CMS Save Point Manager is displayed showing the new cells.
Save Point Manager Dialog
The CMS Save Point Manager dialog is a spreadsheet showing individual save point cells. By default the "Name" column will display the grid cell id (if the save point was created from a grid). Attributes such as hydro, sediment salinity and waves and be turned on/off by toggling the values in the column. If the save points were loading into sms from a *.sp file, the cell row will be highlighted to indicate this.
Storing Save Points in the *.cmcards File
When saving the *.sms project. the save points get stored in the *.cmcards file. An example looks like this:
| !Save Points | |
| HYDRO_OUTPUT_INTERVAL | 5.0 MINUTES |
| SEDIMENT_OUTPUT_INTERVAL | 5.0 MINUTES |
| SALINITY_OUTPUT_INTERVAL | 5.0 MINUTES |
| WAVE_OUTPUT_INTERVAL | 5.0 MINUTES |
| SAVE_POINT | "6, 61" -2867.5 2022.0 HYDRO SEDIMENT WAVE |
| SAVE_POINT | "20, 59" -2517.5 1966.0 HYDRO |
| SAVE_POINT | "10, 31" -2767.5 1182.0 SEDIMENT |
| SAVE_POINT | "11, 31" -2742.5 1182.0 SEDIMENT |
| SAVE_POINT | "10, 32" -2767.5 1210.0 SALINITY |
| SAVE_POINT | "11, 32" -2742.5 1210.0 WAVE |
The SAVE_POINT is formatted [name][x location][y location][hydro (if on)][sediment (if on)][salinity(if on)][wave(if on)]
*.sp/*.spx File for Reading in Save Point Information
Simulation output data gets stored in *sp and *.spx file. The *.sp file is and individual output file. The 8.spx file simply identifies all of the *.sp files that should be loaded for a simulation. An *.sp file looks something like this:
| SAVE_POINT_OUTPUT | eta |
| REFERENCE_TIME | 2001/01/01 00:00 -0000 GMT |
| CREATION_DATE | 2012/05/28 09:02 -0600 GMT |
| CMS_VERSION | 4.00.11 |
| TIME_UNITS | HOURS |
| OUTPUT_UNITS | 'm' |
| NUMBER_POINTS | 2 |
| NAME_BEGIN | |
| '6, 61' | |
| '20, 59' | |

Sms will read in a *.sp file and create a cms-flow save point coverage with the points.
Time Series Plot Wizard
*.sp files that are read into sms can be plotted into a time-series curve. To view the curve do the following:
Load a *.sp file into sms Right-click on Display→Plot Wizard from the menu dialog. Select CMS Save Points from the plot type then click next. Change the coverage to Specified object(s). Now select the points you wish to plot. Now select the Solutions and Datasets then click "Ok". A time series plot is created.
