SC10 — 20-Core, 128 GB CFD HPC Node for Large ANSYS Fluent Simulations

The SC10 node is the balanced professional workhorse of the lineup. It combines real parallel compute — 20 cores and 40 threads — with a substantial 128 GB of RAM and 2 TB of SSD storage. That mix lets you run genuinely large CFD meshes in ANSYS Fluent and solve them at good speed, with plenty of room for the large data files that big and transient simulations generate.

If the smaller nodes are for compact and moderate cases, SC10 is where serious CFD work lives: large meshes, heavier physics, and longer transient runs — without stepping all the way up to a dedicated high-memory machine.

Specifications

This is the first tier that pairs strong cores with serious memory. The 128 GB is four to eight times the RAM of the entry and mid nodes, opening up mesh sizes those configurations cannot touch — while the 20 cores keep solve times down and the 2 TB of SSD gives ample space for large case and data files.

What this node is built for

SC10 is the large-case, balanced tier — enough memory for big meshes, enough cores for good throughput, and enough storage for heavy output. It suits:

• Large meshes — into the high tens of millions of cells (and beyond for simpler physics), well past what 16–32 GB nodes can load.

• Multiphase flows — VOF, Eulerian, and particle models (DPM/DDPM) whose extra equations demand more memory per cell.

• Combustion and reacting flows — detailed chemistry and species transport that a small node cannot hold.

• Conjugate heat transfer and thermal models — electronics cooling, data-center airflow, and other coupled fluid-solid domains at realistic scale.

• Long transient simulations — many time steps writing many data files, where the 2 TB of SSD storage keeps the run from filling the disk.

• Professional, deadline-driven CFD — when the case is large and the turnaround matters, SC10 delivers both capacity and speed.

With 20 cores at 2.5 GHz (turbo to 3.3 GHz) and 128 GB of RAM, the large case both fits and runs, then uses every core to solve it.

The right balance of cores, memory, and storage

In CFD, memory determines the largest mesh you can run — roughly 1 GB of RAM per million cells for a typical steady, single-phase case, and more for complex physics — while cores determine how fast it solves. SC10 is built so neither is the bottleneck for large-but-not-extreme work:

• 128 GB RAM loads large meshes that 16–32 GB nodes reject outright.

• 20 cores solve them with strong parallel throughput.

• 2 TB SSD holds the big case files, autosaves, and transient data dumps without running out of space.

If your simulation is truly enormous or extremely memory-bound — meshes in the hundreds of millions of cells, or very heavy multiphase/combustion — our 1 TB high-memory node is the next step up. And if your cases are moderate, a 16–32 GB node will serve you for less. Tell us your cell count and physics, and we will match you to the right tier.

Fast, roomy SSD storage

The two 1 TB SATA SSDs (about 2 TB total) give you both speed and space: responsive read/write for loading and saving large Fluent files, and enough capacity for long transient runs that write data at many time steps. For big simulations, having room for all those data files — without slow disk I/O holding up the solve — is a real practical advantage.

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 128 GB of memory behind those 20 cores, large cases load comfortably and all cores contribute to a faster solve.

Why rent instead of buy

A dual-CPU server with 128 GB of ECC RAM and 2 TB of SSD is a significant purchase — and it depreciates in your rack between projects. Renting matches cost to workload:

For teams that run large CFD cases periodically rather than constantly, SC10 gives you the capability on demand — with a path up to the 1 TB node for the occasional extreme case.

How it works

1. Tell us about your case — mesh size, physics, and timeline. We confirm SC10 is the right fit.

2. Upload your case files securely.

3. We run it on the node with ANSYS Fluent.

4. You receive your results, ready for post-processing.

Frequently asked questions

How large a mesh can SC10 handle? With 128 GB of RAM, count on large meshes — into the high 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 SC10 different from the smaller nodes? The smaller nodes have 16–32 GB of RAM and suit compact-to-moderate cases. SC10 jumps to 128 GB, which is what lets it run large meshes those nodes cannot load — while keeping 20 cores for good solve speed and 2 TB of storage for big output.

When would I need the 1 TB node instead? For very large, memory-bound simulations — meshes in the hundreds of millions of cells, or extremely heavy physics — where even 128 GB is not enough. We will tell you honestly which tier your case needs.
