Practical use of FEM

• Examples

2
FEM Process Steps
Pre-Processor (INPUT)
Equation Solver (FEA CODE)
Post Processor Displacements Stress
Graphical Outputs
3
SAE Car

• Automotive components require advanced FEM in
  their design and optimization to maximize
  performance and minimize weight and manufacturing
  costs.
• Students at a US university used ALGOR FEA
  software to design components for their SAE car
  which competed in in Michigan in 2002 and took
  6th place
