FEA means

To understand the geometric behaviour of any object by creating virtual environment al in computers applying Material and loading conditions and constraints to understand from where the object may fail and do the required changes before realization

Use below four simple steps

1) prepare a 3D model

2) Apply material

3) create meshing (elements)

4) Apply loading and boundary conditions

5) Run the result

Rerun the above study till your desired output is not satisfied

By this way one can save time and money invested in prototype
