Stand-Damage Menus

The model uses a MENU bar with pull down sub-menus: Use the mouse to move through the menu bar and pull-down menus, then mouse-click to activate your selection. The menu choices are as follows:

Files: Access old or save new input files within the current directory. All input files have the .INP extension. This .INP extension is appended to input files when they are saved. A default data file is used when the program begins. "Reload defaults" reloads this file.

Save File: Saves input data file to disk for accessing later. Use a unique name to avoid overwriting an existing input file. When running many simulations, it helps to annotate each input file with a description and then save it.

Open File: Select from a pick list of available input data files in the current disk directory. All input files have an ".INP" extension.

Reload default file: Replaces current input data with default data, i.e., start with a clean slate. It loads the default data just as if you were starting to begin a new session.

Edit Stand: Edit stand parameters. General simulation data or stand data can be edited.

Edit General Data: Edit or view general simulation data, not specific to any biological component but pertaining to the simulation as a whole.

Stand data: Edit stand data, not specific to host trees but pertaining to the stand as a whole.

Stand details: Edit stand details, not specific to host trees but pertaining to the stand as a whole.

Trees: Edit host species data and defoliation data. You can add a tree host species, edit one or more host species, and delete a host species. You also can add a defoliation year, edit one or more defoliation years, delete a defoliation year, or remove all defoliation.

Add tree species: Adds a host species and all associated default parameters. Since no host can be void of trees, one tree always is supplied to the smallest diameter class. The User Defined tree type can be used to simulate a tree species that is not on the list.

Edit tree species: Select one or more of the current host tree species. Edit each host selected.

Delete tree species: CAUTION: Removes host species and all its associated data from the input data. Save data that you want to reference later. Once a host is removed, it can be recreated only by reentering all the associated data (except the default parameters). See the section on adding a host species.

Defoliation: Edit defoliation data. You can add a defoliation year, edit one or more defoliation years, and delete a defoliation year.

Add defoliation year: Adds a year and the associated defoliation data. The calendar year that you select must be within the simulation range, i.e., between the starting calendar year for the simulation and the last year of the simulation.

Edit defoliation data: Select previously scheduled defoliation years to edit the associated defoliation data. If a particular year is not shown, it has not been added to the list of defoliation years. ALL defoliation is scheduled by the user. The default data set has some scheduled as an example.

Delete defoliation year: Deletes defoliation year from list. Deleting a year removes all defoliation data for that simulation year.

Remove all defoliation: Removes all currently scheduled defoliation years and associated defoliation data. Use this option to run simulation without defoliation.

Manage: Edit management data. You can add a management year, edit one or more management years, and delete a management year.

Add management year: Add a year and the associated management data for stand management. The year that you choose must be within the range of the simulation.

Edit management data: Edit the management stipulations for the year chosen.

Delete management year: Removes a year and associated stand management data from the list of years in which stand management has been scheduled.

Weather: Edit the stand's annual accumulated heat, measured in degree-days. These data affect a tree's growth rate and are species-specific, that is, a value may be optimal for one species but not another.

Edit weather data: Edit the stand's annual accumulated heat, measured in degree-days. These data affect a tree's growth rate and are species-specific, that is, a value may be optimal for one species but not another.

Output: Select which files should be produced during a simulation with Options. After a simulation is run, one can View, Graph, Print, or Save these output files.

Production control: Determines which output files are produced during a simulation. There are two tabular formatted files and four plain ASCII files of numeric data. Two parameters are associated with ASCII output files: the first controls frequency of production and the other controls which portion of the canopy is "viewed" in the output produced.

View output files: Provides a viewing window for the table(s) produced during a simulation. The Arrow keys, Page-up key, and Page-down key allow you to navigate through the table. ESCape exits the viewing window.

Graph output files: Provides a graphics display of the table(s) produced during a simulation.

Print output files: Prints output file(s) produced during a simulation. Make sure the printer is turned on, is on-line, and is using parallel port LPT1. If the printer cannot be initialized (as is the case for laser printers), a WARNING message will be displayed. You can still send output to the printer by answering YES to the question: "Proceed with Print Job?." But proceed with CAUTION since no error checking will be done before the file is sent to the printer. If the printer is not functioning properly, proceeding with the print job may abort the program.

Save output files: Saves specified output files to disk from a list of files generated in the last simulation. Since the stand table is produced by default, it is assumed that you will review it on-screen. To save it you must make an explicit save request. ASCII files are not generated by default, so it is assumed that you want to save them when they have been generated.

Run: Performs simulation based on your input data.

Run Model: Performs simulation based on your input data.

Run Scenario: Performs predefined scenario simulations based on your input data. Runs 10 year simulation for scenarios with No Defoliation, Light Defoliation, and Heavy Defoliation. During simulation, annual notes chart the progression of the simulation. After simulation, view results in Output/View.
