Courant: a State-Adaptive Perceiver-Based Neural Surrogate with Local Support and Interpretable Field Decomposition
Anuj Kumar, Josiah Bjorgaard, Nikolaos Bouklas +2
We introduce "Courant", a Perceiver-based encoder-processor-decoder surrogate model that has latent features exhibiting adaptive specialization and local support in the physical sp…

Case study of a differentiable heterogeneous multiphysics solver for a nuclear fusion application
Jack B. Coughlin, Archis Joglekar, Jonathan Brodrick +1
This work presents a case study of a heterogeneous multiphysics solver from the nuclear fusion domain. At the macroscopic scale, an auto-differentiable ODE solver in JAX computes t…

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…
