- NAME\n\
- xgas - animated simulation of an ideal gas\n\
- \n\
- SYNOPSIS\n\
- xgas [-option ...]\n\
- \n\
- DESCRIPTION\n\
- xgas is a physical simulation of an ideal gas in a heated\n\
- box. Gas molecules move around the box with velocities\n\
- dependent on their temperature. A chamber consisting of two\n\
- boxes contains the gas molecules; the temperature of each\n\
- box can be independently controlled by a scrollbar. When\n\
- gas molecules collide with the walls, their temperature\n\
- approaches that of the box.\n\
- \n\
- Use mouse button 1 to create molecules one at a time at the\n\
- cursor position. Use mouse button 2 to create the maximum\n\
- number of molecules at the cursor position.\n\
- \n\
- OPTIONS\n\
- This is a toolkit program;\n\
- all the usual toolkit options are available.\n\
- \n\
- X DEFAULTS\n\
- The xgas program uses the following X resources:\n\
- \n\
- timeStepSize\n\
- Specifies the simulated time duration in\n\
- microseconds for each cycle of computation.\n\
- \n\
- delay Specifies the real time interval between timestep\n\
- computations.\n\
- \n\
- randomBounce\n\
- In each wall collision, a molecule bounces elasti-\n\
- cally (angle of incidence = angle of reflection). A\n\
- component of randomness is added to this angle.\n\
- RandomBounce varies from 0.0 (no randomness) to 1.0\n\
- (completely random angle of incidence).\n\
- \n\
- ",
- "\
- equilibrium\n\
- During each wall collision, a molecule's kinetic\n\
- energy approaches that corresponding to the tempera-\n\
- ture of the wall. If equilibrium is 1.0, the\n\
- molecule reaches the wall temperature immediately.\n\
- For values between 1.0 and 0.0, the molecule\n\
- approaches the temperature of the wall more slowly.\n\
- \n\
- maxMolecules\n\
- Specifies the maximum number of molecules in the\n\
- simulation.\n\

- BUGS\n\
- When the chamber is resized, molecules should be rearranged\n\
- appropriately. Instead, the molecule arrays are reinitial-\n\
- ized.\n\
