Step 4 is to create a solid CAD model of the hub. This is a complex process which involves a series of assumptions and simplifications which need to be taken into account to get a true picture of the hub's behaviour.

Step 5 is to create a mesh model of the hub, with 72 000 elements. The mesh density is at its greatest in areas of particular interest.

Step 6 is to input the various stresses and loads that the hub will have to cope with, and use a computer programme to solve the model. Today this can be done quickly and reliably though it still needs a lot of interpretation by the engineers and designers.

The final step is to put the lessons learned through FEA and use them to manufacture new improved components which increase your chance of success.

The same FEA process that was used to redesign a car's hub can also be used to improve its 'tub', otherwise known as its chassis.
