XGAS, MOTIF_TOYS, Animated simulation of an ideal gas xgas is a physical simulation of an ideal gas in a heated box. Gas molecules move around the box with velocities dependent on their temperature. A chamber consisting of two boxes contains the gas molecules; the temperature of each box can be independently controlled by a scrollbar. When gas molecules collide with the walls, their temperature approaches that of the box. Use mouse button 1 to create molecules one at a time at the cursor position. Use mouse button 2 to create the maximum number of molecules at the cursor position. Copyright 1991, Massachusetts Institute of Technology. Larry Medwin XGas port under OpenVMS December 1995 ======================= XGas compiles out of the box under OpenVMS. However, you need DECUS X11R4 XAW & XMU library kit available on your system (you can grab it at ada.cenaath.cena.dgac.fr or ftp2.cnam.fr servers into [.DECWINDOWS] directory, or find it at DECUS Web server www.decus.org). Object and executables are also provided. To rebuild, various COMPILE*.COM and LINK*.COM procedure are provided. The resource file XGAS.DAT may be installed either under your SYS$LOGIN directory or (for a system-wide availability) under SYS$COMMON:[DECW$DEFAUKTS.USER] directory with World Read acces. Enjoy !!
