SC28 — 28-Core, 64 GB CFD HPC Node for Fast ANSYS Fluent Solves

The SC28 node brings a newer-generation 28-core platform to larger CFD work at a practical memory budget. A pair of Broadwell Xeons delivers 28 cores and 56 threads of high-clocked compute, paired with 64 GB of RAM — strong solve speed and the memory to take on larger meshes in ANSYS Fluent. For cases that have outgrown the 32 GB nodes but do not yet need the very top capacity, SC28 is a strong fit.

It is a high-performance, larger-case tier: more cores and a newer architecture than the earlier nodes, with 64 GB of memory and a clear path up when your meshes grow.

Specifications

SC28 pairs 28 high-clocked Broadwell cores (2.6 GHz base, 3.5 GHz turbo, 35 MB cache each) with 64 GB of RAM — a newer architecture and higher core count than the Ivy Bridge nodes, combined with the memory to handle larger cases.

What's included with SC28

Every SC28 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

SC28 is the larger-case, high-performance tier for work that needs more than 32 GB but not the top capacity. It suits:

• Larger meshes solved fast — into the tens of millions of cells, with 28 newer-generation cores keeping solve times down.

• Moderate multiphase flows — VOF, Eulerian, and particle models whose extra equations need more memory per cell.

• Conjugate heat transfer and thermal models — coupled fluid-solid domains at a useful scale.

• Transient simulations — unsteady cases that benefit from the extra memory and the strong cores.

• Professional CFD that has outgrown a mid node — the right step up when 32 GB is no longer enough.

With 28 cores at 2.6 GHz (turbo to 3.5 GHz) and 64 GB of RAM, larger cases load comfortably and solve fast across all cores.

Where SC28 fits — and when to size up or down

In CFD, cores set how fast a case solves, and 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. With 64 GB, SC28 is built for larger meshes at strong speed:

• Need more memory? SC29 (96 GB) offers more headroom on the same 28-core platform, and our 128 GB nodes and the 1 TB high-memory node go further.

• Want even more cores for the fastest solves? Our 44-core nodes (SC32 / SC33) push parallel throughput further.

• Working on smaller cases? A 16–32 GB 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 larger, 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 28 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 64 GB of memory behind 28 newer-generation cores, larger cases load comfortably and solve fast.

Why rent instead of buy

For high-performance solves on larger CFD cases, SC28 gives you newer-generation cores and real memory on demand — plus a free course, a month of Claude AI Premium, and a consultation hour — with an easy step up to SC29, the 128 GB nodes, or the 1 TB node when a case calls for more.

How it works — you're in full control

SC28 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 SC28 node.

2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 28 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 SC28 handle? With 64 GB of RAM, count on larger meshes — 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 SC28 different from SC29? Same 28-core Broadwell platform. SC28 has 64 GB of RAM; SC29 has 96 GB. Choose SC28 when 64 GB fits your case; step up to SC29 for more memory headroom.

How is SC28 different from the 32 GB nodes? Same class of newer-generation compute, but SC28 has double the RAM — 64 GB — so it loads larger meshes the 32 GB nodes cannot, the right step up when your cases have grown.

When would I need more cores or more memory? For the fastest solves on cases that fit in less memory, our 44-core nodes push throughput further. For larger, memory-bound cases, our 96–128 GB nodes and the 1 TB node go further. 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.

Get started with SC28

If your CFD cases have outgrown a 32 GB node, SC28 gives you 64 GB and 28 newer-generation cores to run larger meshes fast — with a free CFD course, a month of Claude AI Premium, and a consultation hour included.
