This is the section where it all comes together - all of earlier theory and the mesh data we generated in the previous section. In this section we’re going to  build the core of our solver. This means we’ll build the structure stiffness matrix and solve the system of equations that is the mathematical representation of our structure. 

We’ll round out the section with a validation exercise and compare the deflections from our finite element analysis with those from a simple Euler-Bernoulli deflection calculation. 

Completing this section is a key milestone in our development as we’ll have implemented the core solver. After this our job is to squeeze as much additional information from our model as possible….and generate those nice stress distribution plots!
