Finite Element Libraries: Mixing the “What” with the “How”
Engineering students first learn statics, then strength of materials, and progress to the theories of plates and shells, continuum mechanics, and so on. As the course material advances from simple to complex, students often think that each theory (model) stands on its own, overlooking the fact that simpler models are special cases of the more complex ones. This view guided the development of the finite element (FE) method in the 1960s and 70s, and ultimately led to legacy FE codes adopting an “element-centric” approach.
