OpenFOAM — Neural CFD Surrogates

OpenFOAM + NVIDIA Apollo neural CFD surrogates via API

OpenFOAM is the standard open-source CFD solver — but it requires meshing, boundary condition setup, and hours of compute. SciRouter pairs it with neural surrogates (NVIDIA Apollo, PhysicsNeMo) that give you 500x speedups on standard geometries. Pass a CAD file and boundary conditions, get back drag coefficient, pressure fields, and vorticity.

Quick Start

OpenFOAM + NVIDIA Apollo — Python Examplepython
import requests

r = requests.post(
    "https://scirouter-gateway-production.up.railway.app/v1/physics/cfd-simulate",
    headers={"Authorization": "Bearer sk-sci-..."},
    json={
        "geometry": "cylinder",
        "solver": "apollo",
        "inlet_velocity": 10.0,
        "reynolds": 1e5,
    },
)
result = r.json()["data"]
print(f"Drag coefficient: {result['drag_coefficient']:.3f}")
print(f"Mesh cells: {result['mesh_cells']:,}")
