The name of the main output file is determined by the user during program execution, but defaults to twafer.out. That file begins with an echo back of the user input. For steady-state problems, depending on the print level specified, it then may print the initial guess, some statistics on the solution process, and the steady-state solution. This would be followed by the calculated thermocouple temperatures, and some statistics on work space (memory) used. For transient problems, the output file prints the conditions at time = 0, then prints the solution at the requested time intervals, and ends with the work space statistics.
