What is Computational Fluid Dynamics?

Computational Fluid Dynamics (CFD) is a high-performance computing workload used to model fluid flow, heat transfer, aerodynamics, and related multiphysics behaviour. Unlike conventional workloads, CFD relies on tightly coupled parallel processing across many CPU cores or nodes, demanding balanced compute, memory, networking, and storage infrastructure to deliver predictable performance.

Not Just “More Cores”

For engineering organisations, the objective is not simply to deploy more CPU cores, but to enable faster simulation turnaround time, and drive higher infrastructure considerations for designing CFD platforms, including compute, networking, storage, deployment models, and DiGiCOR's approach to delivering balanced HPC infrastructure.

Key Characteristics

Compute Intensive

In CFD simulations, the performance of the processor is critical to achieve results efficiently by handling complex numerical calculations and parallel processing.

Memory Bound

CFD solution heavily depends on memory bandwidth and balanced memory population. The faster available memory is used across memory channels, the higher the processor and simulation performance will be.

Tightly Coupled Communication

CFD solvers efficiently exchange data between compute nodes, maximising low-latency networking performance essential for MPI performance.

Data Intensive Workflows

CFD generates large volumes of mesh files, checkpoints, and simulation outputs that require scalable, high-performance storage.

Built around how CFD Workloads Actually Behaves

At DiGiCOR, compute nodes are selected according to workload profile and expected solver behaviour, not just core count. Memory is configured to sustain bandwidth and capacity requirements. Interconnect is sized to match cluster scale and communication intensity. Storage is designed to support active job data, checkpoints, results, and long-term retention without creating bottlenecks during execution.

CFD infrastructure should provide:

High compute performance
Balanced memory bandwidth
Low-latency networking
Scalable storage
Flexible deployment

Designed for Real-World CFD Workload

Compute for CFD Throughput and Scalability

Modern CPU platforms have materially improved suitability for CFD and technical computing. Processor selection should be based on solver behaviour rather than core count alone. Memory bandwidth, cache capacity and NUMA configuration all contribute to simulation performance.

DiGiCOR optimises your infrastructure to offer high compute performance through:

Matching CPU architecture to solve behaviour
Balancing core and memory bandwidth
Populating all memory channels
Matching memory capacity to simulation size
Optimising BIOS and NUMA settings
Validating with representative workloads

Networking for Tightly Coupled Workloads

When CFD moves beyond a single workstation or server, networking becomes part of the solver path. Tightly coupled HPC workloads require constant communication between nodes, which is why low-latency, high-throughput fabrics are central to cluster design.

DiGiCOR designs cluster networking around workload scale and operating model, including:

Prioritising low latency networking for MPI workloads
Matching bandwidth to cluster size
Using RDMA where supported
Designing for balanced scalability

Storage for the CFD Data Lifecycle

CFD workflows generate more than solver demand. They also produce mesh data, checkpoints, transient outputs, and simulation results that must be written, accessed, and retained efficiently. Larger clusters therefore often require more capable shared storage approaches to avoid serialization and I/O bottlenecks.

DiGiCOR provides the infrastructure layer that supports CFD data lifecycle via:

Using high-performance storage for active jobs
Separating active an archive storage
Supporting shared team access
Scaling storage with simulation growth

Deployment Models

Different CFD environments have different operational requirements. DiGiCOR supports multiple deployments models to match workloads.

Bare Metal for Maximum Performance

For the most demanding distributed solver workloads, bare metal remains the most direct way to achieve predictable performance.

Virtualised HPC Where Operational Flexibility Matters

Virtualised HPC is valuable when CFD is part of a broader engineering or enterprise environment. It provides stronger workload isolation, greater administrative flexibility, and easier infrastructure management while supporting shared enterprise resources.

Hyperconverged Infrastructure for Selected Patterns

Hyperconverged infrastructure can also have a role in CFD-adjacent environments, especially for departmental deployments, mixed workloads, test and development, or environments where simplified operations are more important than extracting every last percentage point of distributed solver performance.
