is a file identifier such as .DB.) By using a jobname for each analysis,
you insure that no files are overwritten. If you do not specify a jobname,
all files receive the name FILE or file, depending on the operating sys-
tem. You can change the default jobname as follows: by using the initial
jobname entry option when you enter the ANSYS program, either via the
launcher or on the ANSYS execution command. From within the ANSYS
program, you can use either of the following: Command(s):/FILNAME or
GUI: Utility Menu > File > Change Jobname. The /FIL NAME command
is valid only at the Begin level. It lets you change the jobname.

2.2.1.2 Defining an Analysis Title

The /TITLE command (Utility Menu > File > Change Title), defines a title
for the analysis. ANSYS includes the title on all graphics displays and on
the solution output. You can issue the /STITLE command to add subtitles;
these will appear in the output, but not in graphics displays.

2.2.1.3 Defining Units

The ANSYS program does not assume a system of units for your analysis.
Except in magnetic field analyses, you can use any system of units so
long as you make sure that you use that system for all the data you enter.
(Units must be consistent for all input data.) For micro-electro mechanical
systems (MEMS), where dimensions are on the order of microns, see
the conversion factors in System of Units in the ANSYS Coupled-Field
Analysis Guide. Using the /UNITS command, you can set a marker in the
ANSYS database, indicating the system of units that you are using. This
command does not convert data from one system of units to another; it
simply serves as a record for subsequent reviews of the analysis.
