SMS:PTM Model Control

The PTM model control is used to create the program control file, which contains general simulation options. Refer to the PTM manual[SMS:PTM#External Links] for a more detailed description of how these parameters affect the model results.

Time

The Time tab is used to specify time information to be written to the program control file. If a control on the dialog is not enabled, the corresponding keyword will not be written to the program control file. Controls on the dialog are disabled based on the options you have chosen on the other model control tabs. For example, if no trap file is specified on the Files tab, the time controls related to traps will not be available. There is a plot on the dialog of the specified times.

Files

The Files tab is used to specify input and output file information to be written to the program control file.

Pressing the Create input file(s) from data... button on the Files tab will open the Create PTM External Input Files dialog.

Native Sediment Grain Size

1. If "Uniform bed" is selected from the "Options" column an "Options" button is displayed under "Filename". Pressing this button allows the user to create uniform grain sizes for D35, D50 and D90. If the project is saved, the :SEDIMENT_FORMAT card is created, with the keyword UNIFORM and the 3 grain sizes being written out.
2. If Sediment file is selected, the user can manually select the filename by pressing the button under "Filename".
3. Pressing the "Create input file(s) from data" and selecting to create a Native sediment grain size file will automatically toggle the native sediments grain size to "sediments file" and place the new file under the "Filename".

Computations

The Computations tab is used to specify model computation options to be written to the program control file.

Output

The Output tab is used to specify model output options to be written to the program control file.
