Optimal control under uncertainty with joint chance state constraints: almost-everywhere bounds, variance reduction, and application to (bi-)linear elliptic PDEs
Rene Henrion, Georg Stadler, Florian Wechsung
We study optimal control of PDEs under uncertainty with the state variable subject to joint chance constraints. The controls are deterministic, but the states are probabilistic due…
Single-stage gradient-based stellarator coil design: stochastic optimization
Florian Wechsung, Andrew Giuliani, Matt Landreman +2
We extend the single-stage stellarator coil design approach for quasi-symmetry on axis from [Giuliani et al, 2020] to additionally take into account coil manufacturing errors. By m…
Fireshape: a shape optimization toolbox for Firedrake
Alberto Paganini, Florian Wechsung
We introduce Fireshape, an open-source and automated shape optimization toolbox for the finite element software Firedrake. Fireshape is based on the moving mesh method and allows u…
Shape optimisation with nearly conformal transformations
José A. Iglesias, Kevin Sturm, Florian Wechsung
In shape optimisation it is desirable to obtain deformations of a given mesh without negative impact on the mesh quality. We propose a new algorithm using least square formulations…
