Stability for compressible CFD
when standard runs fail
UCF FlowEngine helps difficult OpenFOAM cases keep evolving inside a bounded stability envelope, so engineers spend less time fighting divergence and more time making decisions.
When the solver becomes the problem
Divergence before useful physics
The solver crashes early, before the flow field develops enough to inform engineering decisions. You get noise, not signal.
Restart roulette
Timestep babysitting, relaxation tuning, manual restarts. Each attempt consumes hours with no guarantee of progress.
Fragile runs consume schedule
Runs that technically start but never finish. They burn compute budget and calendar time without producing usable results.
Compressible regimes too risky to explore
Shocks, high Mach, steep density ratios. The standard solver continuation becomes fragile or simply impossible.
A bounded continuation engine for compressible CFD
UCF FlowEngine is not a general-purpose platform. It is built for a specific, high-value problem.
- Built for compressible OpenFOAM cases where standard solver continuation becomes fragile
- Governs time evolution inside a stable basin — adaptive relaxation, divergence containment, early-stop detection
- Does not claim to replace physics, turbulence models, or mesh design — works with the case you already have
- Turns solver survival into usable signal — if the case can converge, FlowEngine finds the path
Works with the case you already have
No proprietary formats. No special setup. Your standard OpenFOAM bundle.
Upload your OpenFOAM bundle
Standard .zip with controlDict, mesh, and boundary conditions. No special format required.
Automated validation
Multi-stage screening: mesh estimation, dictionary parsing, parameter bounds, and security checks. Results in minutes.
Case-fit decision
Validation report tells you whether your case fits. If it does, upgrade to a managed converge run.
Evidence-backed results
Download your evidence pack: PDF report, stability analysis, solver logs, SHA256 checksums, HMAC seal.
What You Get
Every intake produces a cryptographically verified evidence pack
Stability Report
Customer-facing risk assessment: mesh quality, boundary conditions, solver compatibility, and recommended tier.
Intake Manifest
JSON manifest with deterministic run ID, input/output hashes, stage results, and timestamps. Schema-validated.
SHA256 Checksums
Every artifact in the evidence pack is hashed. HMAC-SHA256 seal for Converge runs prevents tampering.
