SC39 — 44-Core, 96 GB CFD HPC Node for Large, Fast ANSYS Fluent Simulations

The SC39 node pairs the highest core count we offer — 44 cores and 88 threads — with 96 GB of RAM. It is built to solve large CFD cases as fast as the range allows in ANSYS Fluent, while still fitting large meshes comfortably in memory. Just below our flagship, SC39 is one of the most capable nodes in the lineup — maximum parallel throughput with substantial memory.

It is a large-case, maximum-performance tier: the most cores in the range, paired with the memory to take on large meshes.

Specifications

SC39 pairs 44 Broadwell cores (the highest count in the lineup, with a large 55 MB cache per CPU) with 96 GB of RAM — maximum parallel throughput combined with the memory to handle large cases.

What's included with SC39

Every SC39 rental comes with extras to help you get the most from it:

• A comprehensive CFD course, free — a full training course to sharpen your simulation skills, included at no extra cost.

• One month of Claude AI Premium — AI assistance to support your engineering, scripting, and problem-solving.

• One hour of free CFD consultation — direct time with our CFD engineers to help set up, troubleshoot, or optimize your case.

These come standard with the node — practical support alongside the compute.

What this node is built for

SC39 is the large-case, maximum-performance tier — strong on both capacity and speed. It suits:

• Large meshes solved as fast as possible — well into the tens of millions of cells, with 44 cores keeping solve times to a minimum.

• Multiphase flows — VOF, Eulerian, and particle models (DPM/DDPM) that demand more memory per cell.

• Combustion and reacting flows — chemistry and species transport at real scale.

• Conjugate heat transfer and thermal models — large coupled fluid-solid domains.

• Large parameter studies on a deadline — the most cores in the range means the most throughput.

With 44 cores (up to 3.6 GHz turbo) and 96 GB of RAM, large cases both fit and run, then solve as fast as the lineup allows.

Maximum cores with large memory — and how to choose

In CFD, memory sets the largest mesh you can run — roughly 1 GB of RAM per million cells for a typical steady, single-phase case, more for complex physics — while cores set how fast it solves. SC39 leads on cores and pairs them with substantial memory: 96 GB loads large meshes, and 44 cores solve them at maximum speed.

• Need more memory or storage? Our flagship SC40 offers 128 GB and ~2 TB of SSD on the same 44-core platform.

• Running very large, memory-bound cases — hundreds of millions of cells? Our 1 TB high-memory node trades cores for maximum memory.

• Working on moderate cases? A lower-memory node will serve you for less.

Tell us your cell count and physics, and we will match you to the tier that fits.

Fast SSD storage

The two 500 GB SATA SSDs deliver responsive read/write for loading case files, writing data, and handling autosaves — keeping a large, fast solve from being held up by slow disk I/O.

How parallel solving works on this node

When you run Fluent in parallel, the solver partitions your mesh across all 44 cores (using algorithms such as METIS), each core solving its share of cells and exchanging boundary data each iteration via MPI. On a single node, that communication runs through fast on-board channels rather than a network, keeping parallel overhead low. With 96 GB of memory behind 44 cores, large cases load comfortably and solve as fast as the range allows.

Why rent instead of buy

A dual-CPU server with flagship 44-core Xeons and 96 GB of ECC RAM is a major purchase that depreciates between projects. Renting matches cost to workload:

For teams running large CFD cases on deadlines, SC39 provides near-flagship performance on demand — with the SC40 flagship and the 1 TB node available when a case calls for more.

How it works — you're in full control

SC39 is yours to drive directly. You connect to the node over a secure remote desktop connection and run everything yourself, exactly as you would on a local workstation:

1. Connect via remote desktop — you get full remote access to the SC39 node.

2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 44 cores at your command.

3. Run and monitor in real time — start, pause, adjust, and watch the solution as it progresses, with complete control throughout.

4. Keep your results — post-process on the node or download your solution and data files whenever you're ready.

You have full authority over the node for the duration of your rental: we provide the hardware and the support, and you run the simulations your way.

Frequently asked questions

How large a mesh can SC39 handle? With 96 GB of RAM, count on large meshes — well into the tens of millions of cells for simpler steady single-phase cases, with complex physics (multiphase, combustion, many transported scalars) needing more memory per cell and so supporting a somewhat smaller mesh. As a guide, allow about 1 GB of RAM per million cells. Send us your case for a precise estimate.

How is SC39 different from the SC40 flagship? Both use the same 44-core E5-2699 v4 platform. SC39 has 96 GB of RAM and ~1 TB of SSD; SC40 has 128 GB and ~2 TB. Choose SC39 when 96 GB fits your case; step up to SC40 for more memory and storage headroom.

What makes SC39 a strong choice at 96 GB? It combines the highest core count in the range (44 cores) with 96 GB of RAM — so it solves large cases as fast as the lineup allows while still fitting them comfortably.

When would I need the 1 TB node instead? For very large, memory-bound simulations where even 96–128 GB is not enough. We will tell you honestly which tier your case needs.

Is my data kept confidential? Yes. Your geometry, case files, and results stay private to you, treated as strictly confidential — and because you run everything yourself over remote desktop, your work stays under your control throughout.
