The document discusses the use of computer simulation software in forging industries. It describes what a simulation is and provides examples of forging simulation software, including Transvalor forge, Deform 3D, and QForm. It then focuses on the DEFORM software, outlining that it is a finite element method simulation system designed for metal forming processes. The major components of DEFORM are described as the pre-processor, simulation, and post-processor. The functions of each component, such as creating input data and displaying results, are summarized. Finally, the advantages and disadvantages of using simulation software are briefly presented.

2. What is Simulation ?
 A simulation is attempt to model a real-life
or hypothetical situation on a computer so
that it can be studied to see how the system
works.
 By changing the variables in the simulation,
prediction may be made about the
behaviour of the system.
 It is a tool to virtually investigate the
behaviour of the system of the system
under study.

3. Forging Simulation Softwares
Transvalor forge
Deform 3d
QForm

4. Overview of DEFORM
 DEFORM is a Finite Element Method (FEM) based
process simulation system designed to analyze
various forming and heat treatment processes
used by metal forming and related industries.
 Unlike general purpose FEM codes, DEFORM is
tailored for deformation modelling. A user friendly
graphical user interface provides easy data
preparation and analysis so engineers can focus
on forming, not on learning a cumbersome
computer system.
 A key component of this is a fully automatic,
optimized remeshing system tailored for large
deformation problems.

5. Major component of DEFORM
 Pre Processor
 Simulation
 Post Processor

6. Pre Processor
 A pre-processor for creating, assembling, or
modifying the data required to analyze the
simulation, and for generating the required
database file.
 The DEFORM pre processor uses a graphical user
interface to assemble the data required to run the
simulation.
 INPUT DATA INCLUDES FOLLOWING THINGS:
a)Objet description
b)Material data
c)Inter object conditions
d)Inter material data
e)Simulation controls

8. Simulation
 A simulation engine for performing the
numerical calculations required to analyze
the process, and writing the results to the
database file.
 The simulation engine reads the database
file, performs the actual solution calculation,
and appends the appropriate solution data
to the database file.
 The simulation engine also works
seamlessly with the Automatic Mesh
Generation (AMG) system to generate a
new FEM mesh on the workpiece whenever

10. Post Processor
 A post-processor for reading the database
file from the simulation engine and
displaying the results graphically and for
extracting numerical data.
 The postprocessor features a graphical
user interface to view geometry, field data
such as strain, temperature, and stress, and
other simulation data such as die loads.
 The postprocessor can also be used to
extract graphic or numerical data for use in
other applications.

12. Advantages
 Study the behaviour of a system
without building it.
 Results are accurate in general,
compared to analytical model.
 Helps to find out unexpected
phenomenon, behaviour of the
system.
 Easy to perform “WHAT- IF” analysis.

13. Disadvantages
 Expensive to build a simulation
model.
 Expensive to conduct simulation.
 Sometimes it is difficult to
interpret the simulation result.
 It is costly to buy.
