The program uses files extensively for data storage and retrieval, especially when solving an analysis. The files are named filename.ext, where filename defaults to the jobname, and ext is a unique two- to four-character extension identifying the contents of the file.
The jobname is a name that you can specify via the /FILNAME command. If you specify no jobname, it defaults to file.
Example 19.1: File Names
If the jobname is bolt, you may have files at the end of an analysis which could include:
| bolt.db | Database file |
| bolt.emat | Element matrices |
| bolt.err | Error and warning messages |
| bolt.log | Command input history |
| bolt.rst | Results file |
Files generated and then deleted before the end of an analysis session are called temporary files. Files that remain after the session are called permanent files. See Table 19.1: Program-Generated Temporary Files and Table 19.2: Program-Generated Permanent Files.
