Engineering without limits
In motorsport and automotive aerodynamics, precision matters. From wing shapes to under hood cooling, the ability to run CFD simulations fast, accurately, and at scale is critical. Simulation isn’t just a support function; it’s a competitive advantage.
Today, however, many CFD teams are working around their tools as much as they’re working with them. Setup times are long. Automation is fragile. CFD results can vary from engineer to engineer. The need for a more flexible, efficient, and scalable approach is growing but making that change can feel like a step into the unknown.
This paper explores the common concerns that makes switching CFD software feel risky, and how bramble was built to address them directly.
Why now?
CFD simulation teams are under more pressure than ever to deliver results faster, across more use cases, with tighter resources and greater consistency. But legacy workflows, often held together by fragile automation and siloed tribal knowledge, can’t keep up.
bramble was built in response to what engineers have grown tired of:
Long setup times and unclear workflows
Inconsistent results across users
Difficulty finding and comparing prior CFD simulations
The cost of licenses and subscriptions
A lack of confidence in who’s running what, and whether it’s “right”
bramble turns that friction into flow. It’s a modern CFD platform with CFD software and data management, designed for speed, clarity, and confidence, whether you’re running daily aero studies or complex thermal interactions.
What makes bramble different?
1. Set up in minutes, not hours
Clear, guided workflows make simulation preparation fast and repeatable, so time goes into engineering, not fighting the tool.
2. High-fidelity results, every time
With template cases and both manual and automated pre-run checks, bramble ensures best practices are followed. So, results stay consistent, no matter who runs the simulation.
3. Track, compare, and find everything
bramble’s built-in data management means every model, mesh, and result is versioned, searchable, and shareable without extra effort.
4. Pay Only for What You Use
bramble’s flexible, usage-based licensing eliminates seat limits and hidden costs, as well as allowing teams to scale effortlessly, run more simulations, and stay within budget.
5. Easy to learn, fast to adopt
Engineers are up and running in a morning, not months with intuitive UI, real support, and no need to change how your team thinks.
What’s holding teams back?
It’s not that better tools don’t exist. It’s that switching tools feels nearly impossible. Years of automation, verification, and internal knowledge are built into existing platforms. For many teams, even entertaining a new CFD tool feels like a high-stakes gamble.
bramble has identified nine key reasons teams hesitate, and built its platform to neutralise every one:

Time saved: 8–10 hours per simulation.
Aeroacoustics simulations in only 4 hrs
10x productivity increase
How bramble makes switching possible
bramble isn’t just a CFD platform, it’s a migration strategy. Every feature is engineered not just for performance, but for compatibility, transparency, and ease of adoption. Here’s how bramble turns each common roadblock into a smooth on-ramp:
Seamless workflow integration
bramble meets teams where they are. Its CFD support engineers work directly with customers to bring existing CFD workflows and meshing recipes into the platform, quickly and reliably. bramble also provides hands-on validation support, ensuring results align with expectations from day one.
Low-risk validation support
Worried about re-correlation? bramble’s side-by-side CFD simulation mode lets you run old and new solvers in parallel and compare deltas in post. Mesh quality, solver convergence, and flow fields can be auto-compared against known baselines, while bramble’s validation toolkit ensures confidence before you ever go live.
Fast, familiar onboarding
bramble’s interface is designed to feel intuitive from the start, especially for engineers transitioning from other major CFD software. Guided workflows and contextual prompts walk users through every step; from mesh setup to boundary assignment to CFD post-processing, making the experience clear and consistent. Teams are up and running within a morning, and when questions do arise, real human support is always available via live chat, phone, or on-site assistance.
Trustworthy, transparent physics
Under the hood, bramble delivers modern solvers: robust RANS and DES models, accurate heat transfer, aeroacoustics and multiphase capabilities. More importantly, its model documentation is fully transparent, so your aero or thermal team can understand why it works, not just that it does.
Flexible, modern licensing
bramble breaks the cycle of vendor lock-in. With a pay-as-you-go model, teams use exactly what they need, when they need it, no license restrictions or subscriptions costs. Pricing is fully transparent: pay only for compute time, per core-hour. And when simulations aren’t running, there are no charges at all.
Migration, not disruption
bramble’s team of experienced CFD engineers, works closely with customer teams to understand current workflows, identify low-risk pilot projects, and build a tailored roadmap for gradual adoption. Whether starting with derivative aero concepts or off-cycle thermal validation, bramble enables a step-by-step transition that scales with growing confidence and minimises disruption.
Open by design
For teams currently using OpenFOAM or STAR CCM+, bramble offers native compatibility, enabling a smooth transition whilst preserving existing solvers, optimisation workflows, and data pipelines. With support for open formats like STL and CSV, users can integrate seamlessly without vendor lock-in or disruptive format changes.
Built for modern compute
The bramble platform runs in the cloud, enabling engineers to launch CFD simulations, review results, and collaborate from virtually anywhere, whether at the track, in the office, or remotely. With just an internet connection, teams gain full access to high-performance CFD tools without being tied to specific hardware. bramble’s on-demand scalability ensures the platform adapts to evolving project demands, while also offering the option to run on-premise when needed.
FIA case study:
Using bramble to simulate car-following-car aerodynamics
The FIA faced a uniquely demanding simulation challenge: accurately modelling the aerodynamic impact of one Formula 1 car closely following another. This “car-following-car” scenario was critical to shaping future technical regulations, but required a solver with both high fidelity and clarity in results.
FIA chose bramble for its:
- Trusted transient solver for car-following cases
- Clear and explainable interface for data exploration
- Confidence in results matching wind tunnel data
bramble provided the FIA with a repeatable, auditable CFD workflow suitable for high-stakes simulation, one that helped inform regulatory decisions affecting every team on the grid.
Aston Martin case study:
Faster aeroacoustics workflow
As Aston Martin expanded its aeroacoustics simulation capabilities, the team needed a CFD software that could improve speed and efficiency without disrupting existing processes. bramble’s intuitive setup, guided workflows, and flexible licensing provided an ideal solution.
By adopting bramble, Aston Martin achieved greater CFD productivity and cost savings, allowing engineers to spend more time on innovation.
Conclusion: A practical path to modern CFD
Adopting bramble doesn’t require an act of faith, it’s a measured, reversible, and supported journey. By tackling the real-world blockers to change, bramble gives engineering teams the freedom to modernise at their own pace, without risking disruption.
Whether your goal is faster design loops, reduced cost per simulation, or more intelligent automation, bramble empowers you to get there, with full control, full transparency, and full support.
