cfdpilot

cfdpilot is an AI CFD engineer for OpenFOAM cases. It is meant for users working directly in a terminal, where it reads an existing case from disk, explains what is happening, applies fixes as diffs that require approval, and then runs the solver. The product is built around troubleshooting OpenFOAM simulations from the user’s own files rather than through uploads or a browser.

Its workflow centers on inspecting the actual setup and logs in a case directory. cfdpilot says it can read folders such as 0/, constant/, and system/, parse logs into structured residuals and divergence events, and report why a simulation diverged. It can auto-detect the solver, turbulence model, whether blockMesh ran, and which log file to parse. The page also shows the agent invoking OpenFOAM commands including blockMesh, checkMesh, setFields, decomposePar, and the relevant solver, while streaming residuals and Courant numbers live to the terminal. When it proposes a fix, it shows a colored diff, waits for confirmation, writes a backup first, and stops after three failed patch attempts.

The tool is described as working over SSH and requiring Python 3.8+ plus an OpenFOAM case directory. Once access is granted, the example flow is to run cfdpilot login and then launch it inside a case directory. It is presented as an access-by-request product. The site also names a set of supported solvers, including simpleFoam, pimpleFoam, interFoam, and rhoPimpleFoam, and says it supports more than 18 solvers in total. In its FAQ, cfdpilot says it is an AI assistant for CFD that works as a copilot for OpenFOAM cases, and the interface is explicitly terminal-based with no browser and no upload.
