Why are "MATLAB codes for finite element analysis" currently ? Because they offer transparency, customizability, and zero licensing barriers for basic solvers. In this article, we will dive deep into the most sought-after, high-temperature (pun intended) FEA MATLAB scripts, covering everything from 1D trusses to 2D steady-state heat transfer.
