SC56

SC56 — 1 TB High-Memory CFD Node for Very Large ANSYS Fluent Cases

The SC56 node is our maximum-memory platform for ANSYS Fluent, pairing a 24-core Intel® Xeon® Gold 5412U CPU with a remarkable 1 TB of RAM and nearly 4 TB of fast NVMe datacenter storage. Where our other nodes lead with core count or GPU acceleration, SC56 leads with capacity: enough memory to hold the very large, memory-bound meshes that overwhelm smaller nodes. When your case is limited by memory, not solve speed — huge meshes, fine resolution, or complex multiphase physics — SC56 is the choice.

It is the memory-first tier in our range: the largest RAM we offer, solid modern compute, and fast NVMe storage for the heavy datasets large cases produce.

Specifications

SC56 leads with memory: 1 TB of RAM — the largest in our lineup — matched to a 24-core Xeon Gold 5412U (up to 3.9 GHz turbo, 45 MB cache). That capacity lets Fluent hold meshes far too large for smaller nodes, while fast NVMe storage keeps case loading and data writes responsive.

What's included with SC56

Every SC56 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

SC56 is the maximum-memory tier in our lineup. It suits:

• Very large meshes — 1 TB of RAM holds cases that simply won't fit on smaller nodes.

• Fine-resolution and high-fidelity models — where cell count climbs into the hundreds of millions.

• Complex multiphase and reacting flows — physics that demand far more memory per cell than simple steady cases.

• Memory-bound work of any kind — where the limit is capacity, not solve throughput.

With 1 TB of RAM behind 24 cores, SC56 lets you run the largest, most memory-hungry cases in our range, while fast NVMe keeps the rest of the workflow flowing.

Memory vs. cores: choosing SC56

SC56's headline is memory, not core count. 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 — while cores determine how fast it solves. With 1 TB, SC56 is matched to very large, memory-bound cases: as a rough guide, hundreds of millions of cells for simpler steady single-phase work, fewer for transient or multiphase physics that use more memory per cell.

• Your bottleneck is solve speed, not memory? Our high-core nodes — SC58 (48-core EPYC), SC62 (48-core dual Xeon), or SC63 (96-core quad Xeon) — spread the work across more cores.

• Want fast per-core performance on moderate cases? See SC57 (high-clock 16-core).

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

Tell us your cell count and physics, and we'll confirm SC56 is the right tier — or point you to one that better balances memory and cores for your case.

Fast NVMe storage

The two 1.88 TB NVMe datacenter SSDs give you nearly 4 TB of high-speed storage — and NVMe delivers markedly faster read/write than SATA. Loading very large geometries and case files, writing solution data, and handling autosaves all run quickly, so a fast solve is never held up by slow disk I/O. With large cases comes large data, and SC56's NVMe keeps that data moving.

How parallel solving works on this node

When you run Fluent in parallel, the solver partitions your mesh across all 24 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. On SC56, the 1 TB of RAM is the key enabler: it lets the solver hold a very large mesh entirely in memory, which is essential for the cases this node is built for.

Why rent instead of buy

A 1 TB server is a major investment to own and maintain — and for many teams, the very large cases that need it are occasional rather than constant. Renting SC56 gives you that capacity on demand — plus a free course, a month of Claude AI Premium, and a consultation hour — without the capital cost or the upkeep.

How it works — you're in full control

SC56 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 SC56 node.

2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 24 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

What makes SC56 special?
Its 1 TB of RAM — the most in our range. That capacity lets Fluent hold very large meshes entirely in memory, making SC56 the right tool for memory-bound cases that other nodes can't fit.

How large a mesh can it handle?
With 1 TB of RAM, plan for very large meshes — into the hundreds 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.

When should I choose SC56 over a high-core node?
Choose SC56 when your case is limited by memory — when it's too large to fit on a smaller node. If your case already fits in memory and you simply want it solved faster, a high-core node like SC58, SC62, or SC63 may serve you better. We'll help you decide.

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.
