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 … WebFEniCS implementation ¶ We first define some parameters of the algorithm. The most important ones concern the number of total alternate minimizations (AM) niter and the parameters controlling the exponent update strategy: niternp corresponds to the number of first (AM) for which p = 1.

Instead of optimizing over a set of admissible shapes, a reference domain is introduced, and it is optimized over a set of admissible transformations. The focus is on the choice of the set of transformations, which we motivate from a continuous …
Web2 PDE-constrained optimization problems Partial di erential equations are used to model physical processes. Optimiza-tion over a PDE arises in at least two broad contexts: determining parameters of a PDE-based model so that the eld values match observations (an inverse problem); and design optimization: for example, of an airplane wing.
