SC47 — Modern 8-Core, 64 GB CFD Node with Fast Cores and NVMe Storage

The SC47 node is a modern, fast workstation for moderate CFD. An AMD Ryzen 7 7700 (Zen 4) delivers 8 cores and 16 threads at high clock speeds — boosting to 5.3 GHz — paired with 64 GB of RAM and fast NVMe storage. For moderate cases where per-core speed and responsive I/O matter more than raw core count, SC47 is a sharp, current-generation choice.

It is a high-clock, fast-storage node: modern cores, generous memory, and NVMe speed for snappy file handling in ANSYS Fluent.

Specifications

SC47 pairs modern Zen 4 cores at high clock speed (up to 5.3 GHz) with NVMe storage — significantly faster than SATA SSDs for loading and writing large case and data files. With 64 GB of RAM behind 8 fast cores, you also get generous memory headroom for the cases this node targets.

What's included with SC47

Every SC47 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

SC47 plays to modern per-core speed and fast I/O rather than high core count. It suits:

• Moderate meshes with strong per-core performance — where fast cores matter more than many cores.

• Pre- and post-processing — meshing, case setup, and results handling, where single-thread speed keeps the workflow responsive.

• I/O-heavy transient runs — fast NVMe storage keeps autosaves and frequent data writes from stalling the solve.

• A modern, snappy CFD machine — for engineers who want a fast, current-generation node with comfortable memory.

• Smaller-to-moderate cases on a deadline — 8 fast Zen 4 cores plus quick storage give a brisk turnaround.

The 64 GB of RAM means memory rarely limits this node for the cases it targets; its strengths are clock speed and storage speed.

Where SC47 fits — fast cores vs. many cores

In CFD, raw core count drives parallel speed-up on large meshes, while per-core performance drives how fast each core works — important for moderate cases and for the many single-threaded steps in a CFD workflow. SC47 leads on modern per-core speed and storage speed, not core count.

• If your work is large, highly parallel meshes needing many cores, our multi-core server nodes (40, 48, even 128 cores) are the better fit.

• If your work is moderate and benefits from fast modern cores, generous memory, and quick NVMe I/O, SC47 is an excellent choice.

• For more cores or a larger cache in a workstation, see our 16-core Ryzen 9 (SC49) or 24-core Core i9 (SC48) nodes.

Fast NVMe storage

The two 1 TB NVMe SSDs (about 2 TB total) deliver much higher read/write speeds than SATA — so loading large case files, writing data, and handling frequent autosaves all happen faster. For transient simulations that write data at many time steps, that speed keeps the workflow moving.

How parallel solving works on this node

When you run Fluent in parallel, the solver partitions your mesh across the 8 cores (using algorithms such as METIS), each core solving its share of cells and exchanging boundary data each iteration via MPI. On a single modern CPU, that communication is fast and overhead is low — and because each core is high-clocked, the per-core work is done quickly. For moderate cases, that delivers a brisk solve, and the NVMe storage keeps file I/O from becoming a bottleneck.

Why rent instead of buy

For a fast, modern CFD node with quick storage and no hardware to own, SC47 gives you per-core speed on demand — with our multi-core server nodes available when a case needs many cores.

How it works — you're in full control

SC47 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 SC47 node.

2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 8 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

Why choose SC47 over a multi-core server node? SC47 trades core count for modern per-core speed and fast NVMe storage. For moderate cases and the many single-threaded steps in a CFD workflow — meshing, setup, post-processing — fast Zen 4 cores and quick I/O make the work snappy. For large, highly parallel meshes, a multi-core server node is the better fit.

How is SC47 different from the entry consumer node? SC47 uses a newer architecture (Zen 4), more cores (8 vs 6), higher clocks, and fast NVMe storage — a clear step up from our entry-level consumer node for moderate, per-core-bound CFD.

How large a mesh can it handle? With 64 GB of RAM, memory allows fairly large meshes, but with 8 cores the practical sweet spot is moderate cases where the fast cores give a brisk solve. Choose this node for speed-per-core, not maximum mesh size. Send us your case and we will advise.

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.
