HPC for ANSYS Fluent

⚙️ Balanced Mid‑Range Computing Solution for CFD

When your CFD workload is too big for entry-level hardware but doesn’t require a full enterprise cluster, a balanced mid‑range platform is the sweet spot. This 20‑core (2.50 GHz) server delivers the parallel throughput, stability, and responsiveness needed for 12–20 million element models—ideal for graduate research, small engineering teams, and advanced student projects.

With ~25% more cores than typical 16‑core entry options, it shortens wall‑clock time for complex physics while keeping costs controlled—perfect for medium‑scale 3D models and coupled multiphysics studies.

💻 High‑Performance Configuration
Key Specifications

CPU: 20 cores @ 2.50 GHz (dual‑socket, server‑class platform)

Workload Size: 12–20M elements (steady + transient)

Use Case Focus: Medium‑scale CFD with complex physics and multiphysics coupling

Reliability: Datacenter‑grade components for 24/7 runs

Why it’s balanced: You get enough core count for efficient domain partitioning and enough per‑core frequency to keep meshing, preprocessing, and post‑processing snappy.

🚀 Built for Medium‑Scale, High‑Fidelity CFD

This system is tuned for ANSYS Fluent, OpenFOAM, and STAR‑CCM+ workflows that push past desktop limits but don’t need a full HPC cluster:

Advanced turbulence: RANS (k‑ε, k‑ω SST), hybrid RANS‑LES, DES

Multiphase & reacting flows: VOF/Eulerian, cavitation, combustion

Thermal & CHT: Conjugate heat transfer with detailed boundary conditions

Transient studies: Time‑accurate aero/thermal events and startup/shutdown cycles

Optimization: DOE, parametric sweeps, and response surfaces

Expect material reductions in wall‑clock time versus 8–16 core desktops, enabling more iterations per week and higher mesh fidelity within project schedules.

🧠 Designed for Coupled Multiphysics (CFD + Thermal + Structural)

Medium‑scale programs increasingly require coupled analyses. This platform sustains:

CFD ⇄ Thermal (CHT) for electronics cooling and heat exchangers

CFD ⇄ FEA (FSI one‑way/two‑way) for aeroelastic or flow‑induced effects

CFD ⇄ EM/Controls co‑simulation pipelines common in R&D

The 20‑core layout provides efficient partition sizing for coupled solvers without starving per‑core performance.

💼 Ideal Use Cases

Aerospace / UAV: external aero, high‑lift, propeller/ducted flows

Automotive: external aero, underhood/underbody cooling, brake/rotor flows

Energy / Process: burners, reacting flows, recuperators, turbomachinery stages

Built environment / HVAC: large‑zone ventilation and thermal comfort

Electronics cooling: CHT with detailed materials and interface resistances

🔧 Quick Wins to Maximize Throughput

Partitioning: Start at ~0.8–1.5M cells per process, then tune after a pilot run.

Time‑step strategy: Use CFL‑guided ramps and dual‑time stepping for transients.

Refinement discipline: Focus mesh on shear layers, recirculation, shocks/gradients; avoid blanket refinement.

Solver order: Run first‑order to reach stability, switch to second‑order for accuracy.

Checkpointing: Frequent autosaves prevent lost progress on long runs.

📊 Why Mid‑Range Over Entry‑Level?

25% more cores means denser partitioning with less per‑core memory pressure.

Higher sustained utilization on complex physics (multiphase/combustion/FSI).

Shorter iteration cycles → more design variants evaluated per week.

You get practical, measurable speed‑ups without the overhead of an enterprise cluster.
