In this blog I wanted to explore the age-old question facing most FEA analysts: Is my model good enough? with examples from my PhD work in knee joint biomechanics.

To create an FE model and run it in a reasonable amount of time, several assumptions and simplifications are needed. One of the aims of one of the knee joint FE models I developed previously was to rapidly identify locations at risk of OA in a patient-specific manner. To achieve the rapid part we used simplified materials models for the main tissues in the knee joint, based on previous literature studies:
