Mapped shape optimization method for rational design of cellular mechanical metamaterials under large deformation

This repository contains an implementation of our paper on International Journal of Numerical Methods in Engineering: "Mapped shape optimization method for rational design of cellular mechanical metamaterials under large deformation". We proposed an adjoint-based method for shape optimization of cellular mechanical metamaterials. We discussed three numerical examples in the paper.

Besides what's already in the paper, we also show an educational example of solving the classic compliance minimization problem by running

python -m src.compliance

and the result is as follows:

compliance.mp4

Here is the objective value versus optimization steps:
