The AQWA Suite uses both ASCII files and binary files for its input and output. All the files are defined by a generic name with a 3 character file extension. The maximum length of the filename is 28 characters (32 with the extension). It is strongly recommended that the filename is related to the program used.
The extension names are related to the file type. The following is a list of the file extension names commonly used in AQWA and AQWA Graphical Supervisor (AGS).

AQWA的计算流程
All programs in the AQWA suite have a facility for gradual progression through any given
analysis. This facility is made possible by structuring each program into a number of distinct stages, called Restart Stages. These are common to all programs in the suite and the user may run, in sequence, any number (there are six stages). Since the restart stages are common to all programs, this allows the user to run more than one program within any analysis (e.g. the user may run the first three stages of AQWA-LINE and then run the last two stages of AQWA-FER, to complete a specific type of analysis).
