SC68

SC68 — Entry 4-Core CFD Node for Learning and Small ANSYS Fluent Cases

The SC68 node is our most accessible starting point for ANSYS Fluent, pairing a 4-core Intel® Core™ i7-6700 (up to 4.0 GHz) with a generous 64 GB of RAM and 1 TB of SATA SSD storage. It's built for getting started with CFD — learning the tools, running tutorials, and solving small cases — with enough memory to hold meshes larger than the core count alone would suggest. When you want a simple, budget-friendly node to learn on or run small simulations, SC68 is the choice.

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

Specifications

SC68 uses a Core i7-6700: 4 cores at up to 4.0 GHz. Behind it, a generous 64 GB of RAM lets it hold small-to-moderate meshes, and two 512 GB SATA SSDs give you 1 TB for case files, solution data, and autosaves.

What's included with SC68

Every SC68 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

SC68 is the entry tier in our range. It suits:

• Learning and training — an accessible node for working through tutorials and building CFD skills.

• Small cases and prototyping — early-stage models and simple geometries.

• Steady runs that fit in 64 GB — where the case is modest and turnaround needs are relaxed.

• Getting started affordably — a simple node to begin CFD without a large commitment.

With 4 cores at up to 4.0 GHz, Fluent partitions your mesh across them for a speed-up on small cases, while the generous 64 GB of RAM lets you hold meshes larger than the core count alone would suggest — handy for setting up and inspecting bigger cases even if they solve slowly here.

Cores vs. memory: choosing SC68

SC68 pairs a modest core count with a generous memory budget. 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, SC68 can hold reasonably sized meshes; its 4 cores then solve them at an entry-level pace, so it's best matched to small cases and learning.

• Want more cores to solve faster? Step up to SC70 (8-core, 5.0 GHz), SC69 or SC72 (12-core), or SG13 (14-core).

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

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

• 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. SC68 is the right call for learning and small cases; for larger or faster work, the nodes above will serve you better.

Fast SSD storage

The two 512 GB SATA SSDs give you 1 TB of responsive storage — quick read/write for loading case files, writing solution data, and handling autosaves, so even an entry node isn't held up by slow disk I/O. (For larger datasets or very I/O-heavy work, our higher-capacity and NVMe-equipped nodes offer more room and speed.)

How parallel solving works on this node

When you run Fluent in parallel, the solver partitions your mesh across all 4 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 cases that fit in 64 GB, those 4 cores deliver an entry-level speed-up — enough to learn on and to handle modest models.

Why rent instead of buy

For learning CFD or running small cases, SC68 gives you a straightforward, accessible node — plus a free course, a month of Claude AI Premium, and a consultation hour — with an easy step up when your meshes grow.

How it works — you're in full control

SC68 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 SC68 node.

2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 4 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 SC68 for?
Anyone starting out with CFD or running small cases — students, those learning ANSYS Fluent, and engineers prototyping simple models who don't need a high-end server.

How large a mesh can it handle?
The generous 64 GB of RAM lets SC68 hold small-to-moderate meshes (about 1 GB of RAM per million cells for simpler steady single-phase cases, fewer for transient or multiphase physics). Bear in mind that with 4 cores, larger meshes will solve slowly — so SC68 is best for smaller cases. Send us your case and we'll advise.

Why pair 64 GB with only 4 cores?
The extra memory lets you set up, load, and inspect meshes larger than the cores can solve quickly — useful for learning and preparation. When you're ready to solve those larger cases at speed, a higher-core node takes over.

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.
