Chapter 1: Getting Started
The program has many finite-element analysis capabilities, ranging from a simple, linear, static analysis
to a complex, nonlinear, transient dynamic analysis. The analysis guides in the documentation set describe
specific procedures for performing analyses for different engineering disciplines.
The process for a typical analysis involves three general tasks:
1.1. Building the Model
1.2. Applying Loads and Obtaining the Solution
1.3. Reviewing the Results1.1. Building the Model
Building a finite element model requires more of your time than any other part of the analysis. First,
you specify a jobname and analysis title. Then, you use the PREP7 preprocessor to define the element
types, element real constants, material properties, and the model geometry.
1.1.1. Specifying a Jobname and Analysis Title
This task is not required for an analysis, but is recommended.
1.1.1.1. Defining the Jobname
The jobname is a name that identifies an analysis job. When you define a jobname for an analysis, the
jobname becomes the first part of the name of all files the analysis creates. ( The ext ension or suffix for
these files' names is a file identifier such as .DB.) By using a jobname for each analysis, you ensure that
no files are overwritten.
If you do not specify a jobname, all files receive the name FILE or file, depending on the operating
system. You can change the default jobname as follows:
- By using the initial jobname entry option when you enter the program, either via the launcher or on
the execution command. - From within the program, you can use either of the following:
Command(s):/FILNAME
GUI: Utility Menu> File> Change Jobname
The /FILNAME command is valid only at the Begin level. It lets you change the jobname even if you
specified an initial jobname after starting the program. The jobname applies only to files you open after
using /FILNAME and not to files that were already open. If you want to start new files (such as the log
file,Jobname.LOG, and error file Jobname.ERR) when you issue /FILNAME, set the Key argument
on /FILNAME to 1. Otherwise, those files that were already open will still have the initial jobname.
