HPC for ANSYS Fluent

⚙️ Balanced Mid-Range Computing Solution for CFD

When your simulation scale exceeds desktop limits but doesn’t yet justify an enterprise cluster, a balanced mid-range platform is the sweet spot. This 20-core (2.50 GHz) server delivers the parallel throughput and per-core responsiveness required for 24–40 million element CFD models—ideal for graduate research, small engineering teams, and advanced student projects tackling complex physics and coupled multiphysics.

With ~25% more cores than 16-core entry systems, it shortens wall-clock time on demanding 3D models and lets you increase mesh fidelity without blowing budgets or schedules.

💻 High-Performance Configuration

Key Specifications

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

Target Mesh Size: 24–40M elements (steady & transient)

Best For: Research labs, small engineering teams, advanced coursework/theses

Focus: Balanced parallel scaling + strong single-core speed for pre/solve/post

Why it’s “balanced”: Enough cores for efficient domain partitioning and enough clock speed to keep meshing, preprocessing, and post-processing responsive.

🚀 Built for High-Fidelity Medium-to-Large CFD

This system is tuned for workloads that demand credible, publishable fidelity:

Turbulence: RANS (k-ε, k-ω SST), hybrid RANS-LES, DES; LES “starts” where appropriate*

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

Thermal/CHT: Conjugate heat transfer with detailed material stacks

Transient physics: Time-accurate aero/thermal events, startups/shutdowns

Design exploration: DOE, response surfaces, and optimization loops

*Full-fidelity LES at 30–40M cells is compute-intensive on any platform; use adaptive refinement, fit-for-purpose models, and smart time-stepping to maximize ROI.

🧩 Designed for Multiphysics: Fluid ⇄ Thermal ⇄ Structural

Modern programs often require coupled analyses. This platform sustains:

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

CFD ⇄ FEA (one-/two-way FSI) for aeroelastic and flow-induced effects

Co-simulation pipelines common in R&D and product development

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, propulsive interactions

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

Energy / Process: combustors, burners, recuperators, turbomachinery stages

Built environment / HVAC: zone ventilation, thermal comfort, wind studies

Electronics cooling: detailed CHT with interface resistances & anisotropy

🔧 Quick Wins to Maximize Throughput

Partitioning: Start around 0.7–1.1M cells per process; tune after a pilot run.

Solver order: Stabilize with first-order, then switch to second-order for accuracy.

Time-step control: CFL-guided ramps + dual-time stepping for transients.

Targeted refinement: Focus on shear layers, recirculation, shocks/gradients; avoid blanket refinement.

Checkpointing: Frequent autosaves protect long runs and enable restartable studies.

📊 Why Mid-Range Over Entry-Level (and Not Enterprise Yet)?

+25% cores vs. 16-core entry → denser partitioning and better scaling on complex physics.

Higher sustained utilization with multiphase/combustion/FSI workloads.

Shorter iteration cycles → more design variants evaluated per week.

Lower TCO and simpler ops than enterprise clusters—great for small teams.

🏁 Final Thoughts

The Balanced Mid-Range Computing Solution for CFD (20 cores @ 2.50 GHz) is the pragmatic choice when you need serious performance for 24–40M element models—without the cost and complexity of enterprise HPC. It delivers the right mix of parallel scalability and per-core speed for advanced turbulence, multiphase physics, and coupled thermal/structural analyses.

Scale your simulations—without overspending.
