Arena Physica Brings Heaviside EM Model to Microsoft Discovery

Arena Physica said on October 13, 2026 that Heaviside, its foundation model for electromagnetism, is now available on Microsoft Discovery, the company's agentic engineering platform. The 350-million-parameter model predicts full 3D electromagnetic field responses in milliseconds, roughly 100,000 times faster than a traditional solver.

• Heaviside-1: 350M parameters trained on 250,000 3D simulations and 500B field samples
• Returns full 3D field responses in milliseconds, up to 100,000x faster than a traditional solver
• Accuracy within one decibel of commercial solvers; 19% error on seen geometries, 33% on unseen
• On Microsoft Discovery it connects to HPC and can switch to a full solver for final validation
