Optimization of an eigenvalue arising in optimal insulation with a lower bound
Sören Bartels, Giuseppe Buttazzo, Hedwig Keller
An eigenvalue problem arising in optimal insulation related to the minimization of the heat decay rate of an insulated body is adapted to enforce a positive lower bound imposed on…
Numerical Approximation of Optimal Convex Shapes in
Sören Bartels, Hedwig Keller, Gerd Wachsmuth
In the optimization of convex domains under a PDE constraint numerical difficulties arise in the approximation of convex domains in . Previous research used a restric…
Numerical Approximation of Optimal Convex and Rotationally Symmetric Shapes for an Eigenvalue Problem arising in Optimal Insulation
Hedwig Keller, Sören Bartels, Gerd Wachsmuth
We are interested in the optimization of convex domains under a PDE constraint. Due to the difficulties of approximating convex domains in , the restriction to rotati…
Numerical solution of a nonlinear eigenvalue problem arising in optimal insulation
Sören Bartels, Giuseppe Buttazzo
The optimal insulation of a heat conducting body by a thin film of variable thickness can be formulated as a nondifferentiable, nonlocal eigenvalue problem. The discretization and…
