Uninstall CHARM

To uninstall CHARM follow the directions given here. Files saved by CHARM will not be removed.

To see an example impact:

Start the program. A pair of tabbed dialogs will appear. For a new user, the tabbed dialogs are the easiest method to enter a release and meteorological description. To see the example results, it may be best to close the dialogs. They can be reopened by selecting Description Dialog Input… or Met Dialog Input… in the Options menu.

Flat terrain version (Charm9)–

  1. Select Plume… in the Displays menu
  2. Press the OK button on the dialog that appears.

Complex terrain version (Charm11) –

  1. Select Open… in the File menu and open the file you find there
  2. Select Open… in the Grid menu and open the file you find there
  3. Select Open… in the MetFile menu and open the file you find there
  4. Select Plume… in the Displays menu
  5. Press the OK button on the dialog that appears.
  6. If you become impatient, you can press Stop (show plume after next complete time step) or Cancel (show plume from last complete time step).

Unlocking the CHARM Software

First, the program must be purchased. That can be done from the Home page. The program is unlocked through the use of a License file supplied by us. The License is created using unique identifiers for the machine upon which it is to be run. The License is valid only for the machine that has those unique identifiers. The license file must be placed in the directory where the appropriate CHARM.exe resides. Next time CHARM starts the file will be read. When the CHARM software is running the unique identifiers are available on the dialog when CHARM starts or when About Charm, in the Help menu is selected.

The unique identifiers can be sent to us manually by you or have CHARM send it automatically. CHARM can send it automatically if you select Existing User Get Key… in the Help menu. Fill out the form and press the Send button.

To send the information manually, you can note the unique identifiers, called Site Code and Machine Identification (MID), and send it in an e-mail to Charm@CharmModel.com along with your name, company name, phone number, and e-mail address.

Each License file that will be returned when the identifiers are provided will be good only on the machine with those identifiers. They are not transferable to other machines. The identifiers for a machine are determined by its hardware configuration and some other factors. The identifiers may change if a machine is booted differently (e.g. to a different partition of the hard drive) or logged in to a different user. A different user may not see the same hard drive or RAM space.

Before you send the identifiers to us it is strongly recommended that the machine be in the configuration (boot and log in) that will be used when CHARM is to be run. Identifiers have changed in the past between initial installation (perhaps logged in as the administrator) and later when the final user is trying to use it.

Free Map Retriever

Maps can be an important feature in presenting the degree of impact from a release, fire, or explosion. For the complex terrain version a map is often the first step in creating a grid. CHARM does include an interface for downloading maps from Yahoo!® via the Internet. Maps from Google™ and Bing Maps™ are not internally available due to use restrictions in commercially available software. A program specifically designed to retrieve maps from Yahoo!®, Google™, and Bing Maps™ has been developed.

After retrieving a map it can be saved in CHARM's format for immediate use. The map is also loaded into the clipboard whenever a save is requested so that it can be used in other programs.

The program can also be used to retrieve a map for an existing grid. When a grid file is read its location and area coverage is used to determine the center point and zoom level for a map.

The program, CHARMInetMaps.exe, is available for downloading without purchase or having to register.

Technical Descriptions

The technical description documents for both versions are available for download. These documents are installed along with the program if the evaluation copies are downloaded and installed.

Non-CHARM Fun Stuff

These programs are just for fun or a waste of time, depending on your perspective. They are provided with no support.

NWSData

This program is only for diehard meteorological data nuts. It allows you to zoom into an area of the world. A region can be selected. The current meteorological data for that region will be downloaded and displayed in standard meteorological display format. The data can be analyzed to show isolines for pressure, temperature, or dew point. Wind streamlines can also be shown.

Download here and then run the program to install.

Sudoku

This program allows you to solve a Sudoku puzzle. Enter the initial definition of the problem or create a new game and save it. Then you select the other entries through the use of drop down boxes. As you progress, the numbers available in each drop down box is updated to only those that are possible. Hints and solving are available. Full undo of hints and your entries is present.

Download here and then run the program to install.
