- └─────────────────┘
-
- TEDDY (short for ThermoDynamics) is an ideal gas model
- simulator based on molecular dynamics. The simulated objects are
- particles confined to a two dimensional container made up of
- various types of walls. The particles playing the role of gas
- molecules collide elastically with each other. The different
- interactions modelled by the different walls are represented by
- the corresponding rules for collision against the walls.
-
- The program is useful as a visual aid and experimental tool
- in various levels of education. Includes the following topics:
- molecular motion, temperature, first and second laws of
- thermodynamics, speed distribution, fluctuations, molecule
- formation, relaxation phenomena.
-
- The program displays the moving particles confined to a
- rectangular vessel and two on-line diagrams simultaneously. There
- are three types of particles: red, green and invisible ones. The
- particle number and the mass of each particle type can be chosen
- independently. There can be maximum 999 particles.
-
- The on-line diagrams can show a variety of distribution
- functions (e.g. pressure, density, temperature versus position,
- velocity and energy) or time-evolution functions (e.g.
- temperature, entropy). Time averaged distribution functions may
- be displayed, as well.
-
- You can design your own experiments (container size and
- shape; type, number, mass, initial velocity and location of the
- particles; type of the diagrams, etc) with a powerful menu system
- and save them on disk for later use.

- │ About TEDDY DEMO │
- └──────────────────────┘
-
- TEDDY DEMO contains all features of the full product except
- the menu system. So you can only use the experiments pre-prepared
- and saved to disk by the full TEDDY program. Find in the TEDDY
- DEMO diskette some interesting experiments (*.MIC files), these
- experiments are intended to demonstrate the capabilities of TEDDY.
- However, TEDDY DEMO alone is a useful aid for classroom
- demonstrations.

- │ Configuration required │
- └────────────────────────────┘
-
- * IBM XT/AT or compatible computer
- * 8087/80x87 coprocessor is recommended
- * at least 320 kbyte main memory
- * hard disk recommended
- * CGA, EGA, VGA or Hercules Graphics Card
- * DOS 3.1 or higher
- * GRAFTABL.COM (DOS utility)
- * for Hercules the MSHERC.COM (Microsoft C utility) or
- a CGA emulator program
- * MORE.COM (DOS utility)
-

- │ Hard disc installation │
- └────────────────────────────┘
-
- If you have a hard disc (or RAM disc) installed in your
- system you should copy TEDDY DEMO there to get faster operation.
-
- Simply create a new directory on your hard disc and copy the
- contents of the TEDDY DEMO disc into this directory, i.e. perform
- the following steps:
-
- C:
- CD \
- MD TEDDEMO
- CD TEDDEMO
- COPY A:\*.*
-
-
- ┌──────────────────────────────────────────┐
- │ Configure your system for TEDDY DEMO │
- └──────────────────────────────────────────┘
-
- TEDDY DEMO needs the GRAFTABL.COM and MORE.COM DOS utilities
- in the DOS path.
-
- If you don't know whether these utilities are in your current
- DOS path or not, perform the following steps:
-
- 1. Type the command:
-
- GRAFTABL
-
- If the system answers "Bad command or file name", the
- GRAFTABL.COM utility is NOT in your current DOS path.
-
- 2. Type:
-
- MORE <NUL
-
- If the system answers "Bad command or file name", the
- MORE.COM utility is NOT in your current DOS path.
-
- If one or both of the two required DOS utilities is not in
- the path, you should modify the path. (Consult your DOS
- guidebook.)
-
- If you intend to run TEDDY DEMO on a Hercules Graphics Card
- do one of the following:
-
- * Before starting TEDDY DEMO load the MSHERC.COM program.
- This is a TSR (Terminate and Stay Resident) utility
- distributed as a part of the Microsoft C 5.1 software
- package.
-
- or
-
- * Before starting TEDDY DEMO load a CGA emulator program.
- There are a variety of such products in the market.

- │ Running TEDDY DEMO │
- └────────────────────────┘
-
- Enter the disc/directory where TEDDY DEMO is located and
- type:
-
- TEDDEMO
-
- This offers you a list of the prepared experiments. You can
- then run the selected experiment by pressing its label (A-H), get
- a short help about the experiment by pressing X followed by the
- experiment label or quit to DOS with the Q key.
