SC13 — 20-Core, 64 GB CFD HPC Node for Fast ANSYS Fluent Solves

The SC13 node brings high-clocked 20-core compute to larger CFD work at a sensible memory budget. It pairs 20 cores and 40 threads with 64 GB of RAM — double the memory of the 32 GB nodes — so you can load and solve larger meshes in ANSYS Fluent at strong speed. For cases that have outgrown a mid-tier node but do not yet need 96–128 GB, SC13 is the natural fit.

It is the high-performance bridge tier: strong cores, 64 GB of memory, and a clear path up when your meshes grow.

Specifications

SC13 pairs 20 high-clocked cores (2.8 GHz base, 3.6 GHz turbo) with 64 GB of RAM — strong solve speed and the memory to take on larger cases than the 16–32 GB nodes.

What's included with SC13

Every SC13 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

SC13 is the larger-case, high-performance tier for work that needs more than 32 GB but not the top capacity. It suits:

• Larger meshes solved fast — into the tens of millions of cells, with 20 high-clocked cores keeping solve times down.

• 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 strong cores.

• Professional CFD that has outgrown a mid node — the right step up when 32 GB is no longer enough.

With 20 cores at 2.8 GHz (turbo to 3.6 GHz) and 64 GB of RAM, larger cases load comfortably and solve fast across all cores.

Where SC13 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. With 64 GB, SC13 is built for larger meshes at strong speed:

• Need more memory? SC14 (96 GB) and SC15 (128 GB, ~2 TB storage) offer more headroom on the same 20-core platform.

• Want more cores at the same memory? The 24-core flagship SC18 (64 GB) steps up the core count and cache.

• Running very large, memory-bound cases? Our 1 TB high-memory node is the right tool.

• 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 20 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 20 high-clocked cores, larger cases load comfortably and solve fast.

Why rent instead of buy

For high-performance solves on larger CFD cases, SC13 gives you strong cores 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 SC14, SC15, the SC18 flagship, or the 1 TB node when a case calls for more.

How it works — you're in full control

SC13 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 SC13 node.

2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 20 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 SC13 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 SC13 different from the 32 GB nodes? Same 20-core high-clocked compute, but SC13 has double the RAM — 64 GB. That lets it load larger meshes the 32 GB nodes cannot, making it the right step up when your cases have grown.

How is SC13 different from SC14 and SC15? All three are 20-core high-clocked platforms; they differ in memory: SC13 has 64 GB, SC14 96 GB, and SC15 128 GB (plus more storage). Step up when your meshes need more memory.

How is SC13 different from the 24-core flagship? The flagship SC18 offers the same 64 GB on a 24-core platform with more cache, for faster solves. SC13 is the 20-core option — strong performance, typically more economical, when the extra cores are not essential.

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 SC13

If your CFD cases have outgrown a 32 GB node, SC13 gives you double the memory and 20 high-clocked cores to run larger meshes fast — with a free CFD course, a month of Claude AI Premium, and a consultation hour included.
