Read, Write, Relax: Why Neural PDE Surrogates Need Both Global and Local Processing
Anuj Kumar, Heiko Zimmermann, Josiah Bjorgaard +4
Recent mesh-based simulation advances have, in no small part, relied on neural surrogates of two distinct families: global models that route information through a small set of late…

Differentiation Strategies for Acoustic Inverse Problems: Admittance Estimation and Shape Optimization
Nikolas Borrel-Jensen, Josiah Bjorgaard
We demonstrate a practical differentiable programming approach for acoustic inverse problems through two applications: admittance estimation and shape optimization for resonance da…

Surrogate-Based Differentiable Pipeline for Shape Optimization
Andrin Rehmann, Nolan Black, Josiah Bjorgaard +5
Gradient-based optimization of engineering designs is limited by non-differentiable components in the typical computer-aided engineering (CAE) workflow, which calculates performanc…
