| Stop: Depressing the Stop button puts the simulator in Stop mode. Stop mode is the default operating mode for all simulators. In Stop mode, you can place elements, change container, heater and cannon parameters, and prepare setups for simulation runs. Only in Stop mode can you access the Standard Menu. Clicking on the Stop button during Run mode or Pause mode halts the simulation and resets the simulator to an initial state. Clicking on Stop also resets the clock.
