Fisher-Information-Based Sensor Placement for Structural Digital Twins: Analytic Results and Benchmarks
Harbir Antil, Animesh Jain, Rainald Löhner
High-fidelity digital twins rely on the accurate assimilation of sensor data into physics-based computational models. In structural applications, such twins aim to identify spatial…

Optimal Boundary Control of Diffusion on Graphs via Linear Programming
Harbir Antil, Rainald Löhner, Felipe Pérez
We propose a linear programming (LP) framework for steady-state diffusion and flux optimization on geometric networks. The state variable satisfies a discrete diffusion law on a we…

Adjoint-based Recovery of Thermal Fields from Displacement or Strain Measurements
Talhah Shamshad Ali Ansari, Rainald Löhner, Roland Wüchner +4
A finite-element method dependant adjoint-based procedure to determine the temperature field of structures based on measured displacements or strains and a set of standard loads is…
