SG13
Unmatched Performance
Built for demanding CFD simulations and computational workloads
Processor
The brain of your simulation power
What This Means for Your Simulations
14 Cores means this server can perform
14 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 14 cores.
Perfect for: Standard CFD projects - significantly faster than typical
4-8 core workstations, allowing quicker design iterations.
The 4.8 GHz clock speed determines how fast each
core performs individual calculations - higher means faster processing for mesh generation,
solving, and post-processing.
Industry-standard CPU benchmark • Higher scores = Faster simulations
Memory (RAM)
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.
DDR4 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
What This Means
This server has
2 storage drives installed.
Each drive is 1.88 TB, giving you a total
storage capacity of 3.75 TB.
HDD storage provides extremely fast
read/write speeds for your simulation files and results.
Multiple drives provide redundancy and can be configured for increased performance or
data protection.
Ultra-fast storage for rapid I/O operations
GPU Acceleration
Massive parallel processing power
What GPU Acceleration Means for Your Simulations
This server has
1 NVIDIA GPUs installed.
Each GPU has 20 GB VRAM, providing a
combined total of 20 GB VRAM for your
most demanding workloads.
Why this matters: GPUs excel at massive parallel processing - while CPUs
have 12-64 cores optimized for sequential tasks, GPUs have thousands of smaller cores
designed specifically for simultaneous calculations. For CFD simulations that can be
parallelized (like solving pressure-velocity coupling or species transport equations), GPUs
can deliver 10-50x speedup over CPU-only solutions.
Perfect for: ANSYS Fluent GPU solver, OpenFOAM GPU-accelerated solvers,
large-scale transient simulations, DEM (Discrete Element Method) coupled with CFD, real-time
visualization during solving, AI/ML-based turbulence modeling, and parametric optimization
studies requiring hundreds of design iterations. GPU acceleration is particularly effective
for explicit solvers and particle tracking algorithms.
VRAM (20 GB total) holds simulation data
on the GPU itself - more VRAM means larger meshes can fit entirely in GPU memory for maximum
performance. Unlike system RAM, VRAM provides ultra-high bandwidth (up to 900 GB/s) directly
to GPU cores, eliminating data transfer bottlenecks during computation.
Industry-standard GPU benchmark • Higher scores = Faster GPU-accelerated solving
Network Speed
Fast file transfers and remote access. Upload meshes and download results quickly from anywhere.
Monthly Traffic
Generous bandwidth allowance for uploading/downloading large simulation files without limits or overage fees.
Operating System
Pre-installed and ready to use. Compatible with ANSYS, OpenFOAM, and other CFD software.
About This Server
SG13 — Entry-Level 14-Core CFD Node for Accessible ANSYS Fluent Solves
The SG13 node is our accessible entry point for ANSYS Fluent, pairing a modern 14-core Intel® Core™ i5-13500 (up to 4.8 GHz) with 64 GB of RAM and nearly 4 TB of HDD storage. It's built for getting CFD work done on small-to-moderate cases — learning the tools, running tutorials, and handling everyday simulations — without the cost of a high-end server. When you want a straightforward, capable node to get started or run moderate cases, SG13 is the choice.
It is the entry tier in our range: modern multi-core compute, a sensible 64 GB memory budget, and generous storage — with a clear path up to faster, larger, and GPU-accelerated nodes as your needs grow.
Specifications
Component | Specification |
|---|---|
CPU | Intel® Core™ i5-13500 — 14 cores / 20 threads (6 P-cores + 8 E-cores), up to 4.8 GHz, 24 MB cache (Raptor Lake) |
Memory | 64 GB RAM |
Storage | 2 × 1.88 TB HDD |
SG13 uses a modern Core i5-13500: 14 cores boosting to 4.8 GHz on the P-cores, with 24 MB of cache. Behind it, 64 GB of RAM holds small-to-moderate meshes, and nearly 4 TB of HDD storage gives plenty of capacity for case files, solution data, and autosaves.
What's included with SG13
Every SG13 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
SG13 is the entry tier in our range. It suits:
Small-to-moderate meshes — 14 cores and 64 GB handle everyday cases comfortably.
Learning and training — an accessible node for working through tutorials and building CFD skills.
Steady and lighter transient runs — wherever the case fits in 64 GB and turnaround needs are modest.
Cost-conscious CFD — capable modern compute without the expense of a high-end server.
With 14 cores at up to 4.8 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 SG13
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, SG13 is matched to small-to-moderate meshes.
Your meshes have grown larger? Step up to a higher-memory node such as SG14 (128 GB) or SC56 (1 TB).
Need more cores? See SC58 (48-core EPYC), SC62 (48-core dual Xeon), or SC63 (96-core quad Xeon).
Want fast per-core performance? 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 match you to the tier that fits.
Storage
The two 1.88 TB HDDs give you nearly 4 TB of generous, cost-effective storage — ample room for case files, solution data, and autosaves. HDDs offer large capacity at low cost; if your work is heavily I/O-bound — for example, long transient runs writing data at every timestep — the faster read/write of our SSD- and NVMe-equipped nodes may suit you better. For typical entry-level workloads, SG13's storage keeps your files comfortably on hand.
How parallel solving works on this node
When you run Fluent in parallel, the solver partitions your mesh across all 14 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 14 cores deliver a solid speed-up.

Frequently asked questions
Who is SG13 for?
Anyone who wants an accessible, capable node for small-to-moderate CFD cases — students, those learning Fluent, and engineers running everyday simulations that don't require a high-end server.
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.
Is the HDD storage fast enough?
For typical entry-level workloads, yes. HDDs trade speed for capacity and cost, which suits this tier well. If your work is heavily I/O-bound, our SSD- and NVMe-equipped nodes offer faster storage — we'll help you choose.
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.
