The coding agent that understands physics.

Ask how a particle-in-cell code deposits charge. PhysicsCode reads the source, reasons about the physics, and answers in your terminal.

A real session: PhysicsCode explains charge deposition in the IPPL particle-in-cell code.

Reads the source

Navigates large simulation codebases and traces how the numerics are actually implemented, not how the paper says they are.

Reasons about the physics

Connects code to equations: discretisations, conservation laws, units, and the assumptions hiding in a kernel.

Cites its sources

Answers are grounded in a retrieval index of scientific codes, with the repositories, files and symbols it used listed alongside.
