# AgentFEM Case Instructions

- Export through `step.solve_result(output=...)`; for custom loops use
  `io.ResultWriter`. Do not hand-write connectivity, node permutations or XDMF
  blocks. Use the result manifest's recommended visualization artifact.
- Keep point/cell/quadrature fields distinct. Use explicit cell identities for
  external arrays, not equal-length assumptions or default interface smoothing.
- Apply Warp once to reference geometry, never again to already deformed output.

- Keep temperature constraints, heat sources, heat fluxes, and convection as
  distinct engineering concepts.
- Run `agentfem doctor`, `agentfem check`, and `agentfem run` in that order.
- Inspect the result manifest referenced by
  `outputs/latest.json` before interpreting the field.
- Preserve units and sign conventions in every change.
