What This Means for Your Simulations

12 Cores means this server can perform 12 calculations simultaneously.

Why this matters: CFD simulations divide your fluid domain into millions of cells. Each core can solve equations for different cells at the same time - more cores = dramatically faster solutions. A simulation that takes 24 hours on a 4-core laptop could finish in 3-4 hours with 12 cores.

Perfect for: Standard CFD projects - significantly faster than typical 4-8 core workstations, allowing quicker design iterations.

The 4.3 GHz clock speed determines how fast each core performs individual calculations - higher means faster processing for mesh generation, solving, and post-processing.

Memory (RAM)

64 GB
Type
DDR5

What This Means

64 GB is your simulation's "working space" - it holds all active data: mesh geometry, fluid properties, boundary conditions, and results during solving.

DDR5 provides high-bandwidth data access essential for CFD solvers that read and update millions of cell values thousands of times during iterations. This capacity handles standard to medium simulations with headroom for mesh refinement - significantly more than typical workstations with 16-32GB. Adequate RAM prevents solver crashes and slow virtual memory usage.

High-bandwidth memory for lightning-fast data access

Storage

2 x 1 TB
Type
SATA SSD

What This Means

This server has 2 storage drives installed. Each drive is 1 TB, giving you a total storage capacity of 2 TB.

SATA SSD storage provides extremely fast read/write speeds for your simulation files and results. SSDs are much faster than traditional hard drives - ideal for loading large mesh files and saving iteration data quickly. Multiple drives provide redundancy and can be configured for increased performance or data protection.

Ultra-fast storage for rapid I/O operations

Network Speed

1 Gbit/s

Fast file transfers and remote access. Upload meshes and download results quickly from anywhere.

Monthly Traffic

Unlimited

Generous bandwidth allowance for uploading/downloading large simulation files without limits or overage fees.

Operating System

Windows 11

Pre-installed and ready to use. Compatible with ANSYS, OpenFOAM, and other CFD software.

About This Server

SC69 — 12-Core CFD Node for Cost-Effective ANSYS Fluent Solves

The SC69 node offers accessible multi-core CFD for ANSYS Fluent, pairing a 12-core AMD Ryzen™ 9 3900 (up to 4.3 GHz) with 64 GB of RAM and 2 TB of SATA SSD storage. With a solid core count at a cost-effective price point, it's well suited to small-to-moderate cases, everyday work, and getting CFD done without a high-end server. When you want a dependable, value-oriented node with a decent core count, SC69 is the choice.

It is the value, multi-core entry tier in our range: a capable 12-core CPU, a sensible 64 GB memory budget, and responsive SSD storage — with a clear path up to higher-core, higher-memory, and GPU nodes as your needs grow.

Storage

2 × 1 TB SATA SSD

SC69 uses a Ryzen 9 3900: 12 cores boosting to 4.3 GHz with 64 MB of L3 cache — a solid multi-core CPU for the tier. Behind it, 64 GB of RAM holds small-to-moderate meshes, and two 1 TB SATA SSDs give you 2 TB for case files, solution data, and autosaves.

What's included with SC69

Every SC69 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

SC69 is the value, multi-core entry tier in our range. It suits:

  • Small-to-moderate meshes solved in parallel — 12 cores spread the work for a solid speed-up.

  • Learning, prototyping, and everyday CFD — a capable, cost-effective node for routine work.

  • Steady and lighter transient runs — wherever the case fits in 64 GB and turnaround needs are modest.

  • Cost-conscious simulation — a real multi-core CPU without the expense of a high-end server.

With 12 cores at up to 4.3 GHz, Fluent partitions your mesh across them for a solid speed-up on small-to-moderate cases, while 64 GB of RAM keeps everyday simulations in memory.

Cores vs. memory: choosing SC69

In CFD, cores determine how fast a case solves, while memory sets the largest mesh you can run — roughly 1 GB of RAM per million cells for a typical steady, single-phase case. With 64 GB and 12 cores, SC69 is matched to small-to-moderate cases solved at a steady pace.

  • Want the same CPU class but more memory? Step up to SC72 (Ryzen 9 3900X, 128 GB).

  • Need more memory generally? See SC56 (1 TB high-memory).

  • Want fast per-core performance? See SC70 (8-core, 5.0 GHz) or SC57 (16-core, 5.7 GHz).

  • Need a high core count? See SC58 (48-core EPYC), SC62 (48-core dual Xeon), or SC63 (96-core quad Xeon).

  • Want GPU acceleration? Our GPU tiers (GP1, GP2) run Fluent's native GPU solver.

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

Fast SSD storage

The two 1 TB SATA SSDs give you 2 TB of responsive storage — quick read/write for loading case files, writing solution data, and handling autosaves, so a fast solve is never held up by slow disk I/O. (If you need the higher throughput of NVMe for very I/O-heavy work, ask us about our NVMe-equipped nodes.)

How parallel solving works on this node

When you run Fluent in parallel, the solver partitions your mesh across all 12 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-chip channels rather than a network, keeping parallel overhead low. For small-to-moderate cases that fit in 64 GB, those 12 cores deliver a solid speed-up.

For cost-effective multi-core CFD, SC69 gives you a capable 12-core CPU — plus a free course, a month of Claude AI Premium, and a consultation hour — with an easy step up when your meshes or core needs grow.

How it works — you're in full control

SC69 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 SC69 node.

  2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 12 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

Who is SC69 for?
Anyone who wants a cost-effective node with a real multi-core CPU for small-to-moderate CFD cases — everyday work, learning, and prototyping.

How large a mesh can it handle?
With 64 GB of RAM, plan for small-to-moderate meshes — into the low tens of millions of cells for simpler steady single-phase cases, fewer for transient or multiphase physics (about 1 GB of RAM per million cells is a good starting estimate). Send us your case for a precise answer.

How is SC69 different from SC72?
Both use a 12-core Zen 2 Ryzen. SC69 pairs the Ryzen 9 3900 with 64 GB of RAM and 2 TB of storage; SC72 steps up to the higher-clocked 3900X with 128 GB of RAM and 4 TB of storage. Choose SC72 when you need more memory headroom.

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.
