Finite Element Models are representations
used for performing computeraided engineering analysis (CAEA) of
products. They are complementary to computeraided design (CAD)
models, which are mainly geometric representations of products.
A Finite Element Model consists of:
 a system representation, consisting of:
 a Mesh objects set (containing Node and Element objects) 
 a Properties objects set (containing Propertytype
objects) 
 a Materials objects set (containing Materialtype
objects) 
 an Axis objects set (containing Axistype objects) 

 various environment actions representations, each consisting
of:
 an Analysis Case object sets, defining implicitly the type of analysis
(solution procedure) expected, and possibly containing:
 a Restraints objects set (containing Restrainttype
objects) 
 a Loads objects set (containing Loadtype objects) 
 a (NS) Masses objects set (containing Masstype objects 

 for each Analysis Case, a Solution objects set, defining the
type of results sought:
 images 
 analyses 
 reports 
 graphs... 


The Finite Element Model can initiate a solution process when a sufficient amount
of specifications have been captured in the objects constituting the
representations of the model.
At the creation of a Finite Element Model, the program automatically
generates the system representation template, and proposes to also
generate an Analysis Case template for the environment representation
and also for indicating the type of solution procedure sought.


This task shows you how to
create a Finite Element Model, and optionally an Analysis Case.


If you do not have the
ELFINI Structural Analysis product license, your Finite Element Model can
simultaneously contain at most one Static Analysis Case and one Frequency Analysis
Case.


You can use the sample01.CATPart document from the
samples directory for this
task.


1. Select Start > Analysis & Simulation >
Generative Structural Analysis.
The New Analysis Case dialog box is displayed. You can create several
types of template:
 Static
Analysis Case 
 Frequency Analysis Case 
 Free Frequency Analysis Case 


2. Activate the Static Analysis item in the list and click
OK.
An empty Analysis document containing the Analysis toolbar is created.
The Finite Element Model specification tree template displayed on the left
shows the standard system representation objects sets and a Static
Analysis Case representation, consisting of the following (empty) object
sets:
 Restraints 
 Loads 
 Solution 


You could also have activated the
Frequency Analysis item in the New Analysis Case dialog box.
The Finite Element Model specification tree template displayed on the left of
the created Analysis document would then contain a Frequency Analysis Case representation, consisting of the following (empty) object
sets:
 Restraints 
 Masses 
 Solution 


You can activate the Keep As
Default switch in the New Analysis Case dialog box if you want to set the
current choice as a default choice.
When you have the ELFINI Structural
Analysis product installed, the Finite Element Model can contain an arbitrary number
of (Static and/or Frequency) Analysis Cases.
