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…

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…
