Topology optimization (determining the optimal material layout within a given design space) is widely used in aerospace and additive manufacturing. The "88-line" code is a famous benchmark in the FEA community. : Handles complex effects like radiation, where thermal
Here’s a complete, minimal M-file that assembles and solves a 2D truss bridge: Pre-Processing (Geometry and Meshing)
Fixed temperatures (e.g., a surface held at 100°C).
