SC38 — 44-Core, 64 GB CFD HPC Node for Fast ANSYS Fluent Solves

The SC38 node pairs the highest core count we offer — 44 cores and 88 threads — with 64 GB of RAM. It is built to solve larger CFD cases as fast as the range allows in ANSYS Fluent, at a practical memory budget. When your case fits in 64 GB and you want maximum parallel throughput behind it, SC38 is part of our top-performing 44-core family.

It is a high-performance, larger-case tier: the most cores in the range, paired with 64 GB of memory and a clear path up when your meshes grow.

Specifications

SC38 pairs 44 Broadwell cores (the highest count in the lineup, with a large 55 MB cache per CPU) with 64 GB of RAM — maximum parallel throughput combined with the memory to handle larger cases.

What's included with SC38

Every SC38 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

SC38 is the larger-case, maximum-performance tier for work that needs more than 32 GB but not the top capacity. It suits:

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

• 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 maximum cores.

• 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 64 GB of RAM, larger cases load comfortably and solve as fast as the lineup allows.

Where SC38 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. SC38 leads on cores and pairs them with 64 GB — built for larger meshes at maximum speed:

• Need more memory? SC39 (96 GB) and the flagship SC40 (128 GB, ~2 TB storage) offer more headroom on the same 44-core platform.

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

• 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 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 64 GB of memory behind 44 cores, larger cases load comfortably and solve as fast as the range allows.

Why rent instead of buy

For maximum-throughput solves on larger CFD cases, SC38 gives you the most cores in the range 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 SC39, the SC40 flagship, or the 1 TB node when a case calls for more.

How it works — you're in full control

SC38 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 SC38 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 SC38 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 SC38 different from SC39 and SC40? All three use the same 44-core E5-2699 v4 platform; they differ in memory: SC38 has 64 GB, SC39 96 GB, and the flagship SC40 128 GB (plus more storage). Step up when your meshes need more memory.

How is SC38 different from the 32 GB 44-core node? SC38 has double the RAM — 64 GB — so it loads larger meshes than a 32 GB node while keeping the same maximum 44-core throughput. The right step up when your cases have grown.

When would I need the 1 TB node instead? For very large, memory-bound simulations where 64–128 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.

Get started with SC38

If your CFD cases have outgrown a 32 GB node, SC38 gives you 64 GB and the most cores in the range to run larger meshes as fast as possible — with a free CFD course, a month of Claude AI Premium, and a consultation hour included.
