HASEL Pressure-Actuated Topology Optimization (FEniCS)

This repo contains a mixed u–p (displacement–pressure) topology optimization for HASEL-like actuators in FEniCS with fenics_adjoint + IPOPT.

Quick start

• Run forward/opt: python3 solid-topopt-hasel2.py
• Outputs: ./<folder_name>/* (displacements, stress, pressure, densities)

Notes

• Two load cases: low- and high-pressure boundary conditions.
• Objective: maximize upward tip motion at low P with smoothing.
• Extra hard constraint: force near-zero tip motion at high P.

See the code comments for details.
