Topology Optimisation
Overview
Section titled “Overview”This guide will cover rfx’s topology optimisation pipeline:
- Density parameterisation — continuous relaxation of material presence
- Cone filter — minimum feature-size enforcement via spatial filtering
- Smooth Heaviside projection — binarisation with differentiable thresholding
- Beta continuation schedule — progressive sharpening toward 0/1 designs
- Gradient computation —

See Gradient Behavior for where gradients are reliable and Inverse Design for the broader design framework.
