Chapter 1: Getting Started with ANSYS<br />

The ANSYS program has many finite-element analysis capabilities, ranging from a simple, linear, static analysis<br />

to a complex, nonlinear, transient dynamic analysis. The analysis guides in the ANSYS documentation<br />

set describe specific procedures for performing analyses for different engineering disciplines.<br />

The process for a typical ANSYS analysis involves three general tasks:<br />

1.1. Building the Model<br />

1.2. Applying Loads and Obtaining the Solution<br />

1.3. Reviewing the Results<br />

1.1. Building the Model<br />

Building a finite element model requires more of your time than any other part of the analysis. First, you<br />

specify a jobname and analysis title. Then, you use the PREP7 preprocessor to define the element types,<br />

element real constants, material properties, and the model geometry.<br />

1.1.1. Specifying a Jobname and <strong>Analysis</strong> Title<br />

This task is not required for an analysis, but is recommended.<br />

1.1.1.1. Defining the Jobname<br />

The jobname is a name that identifies the ANSYS job. When you define a jobname for an analysis, the jobname<br />

becomes the first part of the name of all files the analysis creates. (The extension or suffix for these files'<br />

names is a file identifier such as .DB.) By using a jobname for each analysis, you ensure that no files are<br />

overwritten.<br />

If you do not specify a jobname, all files receive the name FILE or file, depending on the operating system.<br />

You can change the default jobname as follows:<br />

• By using the initial jobname entry option when you enter the ANSYS program, either via the launcher<br />

or on the ANSYS execution command.<br />

• From within the ANSYS program, you can use either of the following:<br />

Command(s): /FILNAME<br />

GUI: Utility Menu> File> Change Jobname<br />

The /FILNAME command is valid only at the Begin level. It lets you change the jobname even if you specified<br />

an initial jobname at ANSYS entry. The jobname applies only to files you open after using /FILNAME and<br />

not to files that were already open. If you want to start new files (such as the log file, Jobname.LOG, and<br />

error file Jobname.ERR) when you issue /FILNAME, set the Key argument on /FILNAME to 1. Otherwise,<br />

those files that were already open will still have the initial jobname.<br />
