Fenics shape optimization

WebThis educational code written for FEniCS is for compliance minimization in structural optimization, in two dimensions. The code is based on a level set formulation and on the distributed expression of the shape derivative, and exploits the powerful features of FEniCS to solve complicated PDEs with a simple implementation. The code is written for … WebWith the forward problem solved once, dolfin_adjoint has built a tape of the forward model; it will use this tape to drive the optimisation, by repeatedly solving the forward model and the adjoint model for varying control …
