HPC for ANSYS Fluent

⚙️ Balanced Mid-Range Computing Solution for CFD

When your projects outgrow entry-level desktops but don’t yet need an enterprise cluster, a balanced mid-range server is the sweet spot. This 20-core (2.50 GHz) platform delivers the parallel throughput and per-core responsiveness required for 3–5 million element CFD models—ideal for researchers, small engineering teams, and advanced students using ANSYS Fluent, OpenFOAM, or STAR-CCM+.

With ~25% more cores than 16-core entry options, you’ll see meaningful reductions in wall-clock time on complex physics and better efficiency for coupled multiphysics workflows (fluid, thermal, structural).

💻 High-Performance Configuration

Key Specifications

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

Target Mesh Size: 3–5M elements (steady & transient)

Best For: Graduate research, small teams, advanced coursework/theses

Focus: Balanced parallel scaling + solid 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 Medium-Scale, High-Credibility CFD

This system is tuned for workloads that exceed desktop limits and demand reliable, publishable results:

Turbulence: RANS (k-ε, k-ω SST), transition models, hybrid RANS-LES/ DES “starts”

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

Thermal/CHT: Conjugate heat transfer with detailed materials/interfaces

Transient physics: Time-accurate aero/thermal events and start-up/shut-down cycles

Design exploration: DOE, response surfaces, and parametric sweeps

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

🧩 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 product development and research

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: zone ventilation, thermal comfort, wind studies

Electronics cooling: detailed CHT with interface resistances & anisotropy

🔧 Quick Wins to Maximize Throughput

Partitioning: Start around 1.0–1.5M cells per process (for 3–5M total); refine 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?

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

Higher sustained utilization with multiphase/combustion/FSI workloads.

Shorter iteration cycles → more design variants evaluated each week.

Lower TCO and simpler ops than jumping straight to enterprise clusters.
