Run OpenFOAM on Cloud HPC with AI Agents
SimuXAI is an AI-powered platform for running OpenFOAM in the cloud. Instead of hand-editing dictionaries and managing HPC clusters, you describe your CFD problem in plain English. An LLM-based AI agent builds the complete OpenFOAM case — geometry handling, meshing, boundary conditions, turbulence model, solver settings — and executes it in parallel on managed high-performance computing (HPC) infrastructure. You get post-processed results in your browser, not a folder of raw time directories.
An AI agent that builds your OpenFOAM case
The SimuXAI OpenFOAM agent is a multi-agent LLM system trained on OpenFOAM workflows. It interviews you about your problem — flow regime, geometry, boundary conditions, target quantities — and generates a complete, consistent case: blockMeshDict or snappyHexMeshDict, fvSchemes, fvSolution, turbulence properties, and initial fields. Errors that would normally cost hours of forum searching are caught and fixed automatically during execution.
Parallel OpenFOAM on HPC compute
Every simulation runs on managed cloud HPC nodes. Domain decomposition (decomposePar), parallel execution with MPI, and reconstruction are fully automated — you never write a job script or size a cluster. Compute scales with your case: small teaching cases run on a few cores, while large industrial meshes are distributed across many-core nodes. You pay for compute time used, with no idle infrastructure.
OpenFOAM post-processing in the browser
Results are post-processed in the cloud and served to your browser through CloudView: contour plots, streamlines, slices, force coefficients, and residual monitoring — no ParaView installation required. The AI agent can also summarize results and generate report-ready figures on request.

Frequently asked questions
Can I run OpenFOAM in the cloud without installing anything?
Yes. SimuXAI runs OpenFOAM entirely on managed cloud infrastructure. You interact through your browser — describe the problem, review the AI-generated case, launch, and inspect results. No local OpenFOAM installation, Docker image, or Linux environment is needed.
Does SimuXAI run OpenFOAM in parallel on HPC?
Yes. Cases are automatically decomposed and executed in parallel with MPI on cloud HPC compute nodes. Decomposition strategy and core count are chosen based on mesh size, and results are reconstructed automatically.
How does the OpenFOAM AI agent (LLM) work?
A multi-agent large language model system guides an interview about your CFD problem, then generates the full OpenFOAM case files, validates them, executes the run, monitors convergence, and post-processes the output. It is grounded in OpenFOAM documentation and validated tutorial workflows.
What kinds of CFD problems can I solve?
Incompressible and compressible flows, RANS and LES turbulence, heat transfer, multiphase (VOF) flows, porous media, and species mixing — including classic benchmarks like the Ahmed body and von Kármán vortex street, and applied cases like pedestrian wind comfort and clean-room airflow.
How much does it cost to run OpenFOAM on cloud HPC?
SimuXAI has a free tier for getting started, and paid plans where you pay for the compute you use. See the pricing page for current plans.
