FEA (Finite Element Analysis) is a computer simulation technique used in engineering analysis.

FEA allows us to simulate real life scenarios and assists in answering some of the following questions: -

Will it break under load?
Can I save weight in my design?
What is the effect of shock or vibration?
What effect does heat or cold have on my product performance?
Will my product pass a drop test?
How does heat transfer through my part?
