A Finite Element Approximation of an Optimal Insulation Problem with Convective Heat Transfer

Harbir Antil, Alex Kaltenbach, Keegan L. A. Kirk

A finite element discretization of an optimal insulation problem with convective heat transfer is considered. The model is formulated as a non-smooth, two-variable convex minimizat…

A Priori and A Posteriori Error Identities for Vectorial Problems via Convex Duality

P. A. Gazca-Orozco, A. Kaltenbach

Convex duality has been leveraged in recent years to derive a posteriori error estimates and identities for a wide range of non-linear and non-smooth scalar problems. By employing…
