Why centron

Computing power in step with the iterations

CFD thrives on iterations – the faster a run, the more variants the project generates.

Cores by case size

Large meshes are assigned large instances or dedicated servers – smaller versions run in parallel on several VMs.

GPU acceleration

GPU-enabled solvers and post-processing benefit from dedicated RTX cards from €92.59 per month (billed by the hour).

Results archived

Simulation data is transferred to S3 – every calculated variant remains traceable and comparable.

Budget per project

Hourly billing fits in well with project-based costing – no hardware that sits idle between jobs.

Use cases

Ready for the future of flow simulation with cloud GPUs

Modern product development demands precise flow analyses, fast decisions and efficient use of resources. Classic methods reach their limits with complex physics – wind tunnel tests are expensive and inflexible. CFD offers enormous potential but in practice often fails for lack of computing power, know-how or suitable tools.

Why CFD is so valuable

Flow simulations are the key to better products – but with complex physics and transient scenarios, classic calculation approaches quickly reach their limits. Long computing times and simplified models lead to inaccurate results and missed opportunities. The geometry for it is created on CAD in the cloud.

More computing power – lower costs

With GPU-based CFD you significantly accelerate your simulations while reducing the cost per run. Compared with classic CPU clusters, you benefit from lower investment – with equivalent or even higher performance on Cloud GPU.

Latest hardware – available immediately

Whether high-end simulation or demanding visualisation: the infrastructure delivers maximum performance, razor-sharp results and smooth processes – with no waiting; large meshes compute on dedicated servers or HPC instances.

Total costs under control

Purchasing, maintaining and continually updating your own CFD hardware is expensive. With cloud-based solutions, your spending remains predictable and calculable – and you benefit from greater flexibility for your projects at the same time.

Batch processing instead of waiting time

Parameter studies carried out in parallel rather than sequentially

Instead of tying up a workstation for weeks on end, ten variants run in parallel on ten instances – orchestrated via scripts or Kubernetes jobs. Results are collected by S3, whilst post-processing is handled by a GPU instance running ParaView.

In a nutshell

How much does CFD simulation cost at Centron?

CFD simulation in the cloud: flow calculations on HPC and GPU instances – computing power on demand instead of your own clusters. The core component is a dedicated server from €29.99 per month – billed by the hour, with no minimum contract term. This is supplemented, as required, by Cloud GPU and S3 Object Storage. All data remains in Germany: in our own data centres in Hallstadt near Bamberg, certified to ISO 27001 on the basis of IT-Grundschutz and BSI C5:2020 Type 1. New accounts receive a €200 starting credit.

AI & Compute FAQ

Frequently asked questions

What is CFD and why is it important?

CFD (computational fluid dynamics) refers to the numerical flow simulation of physical processes – for instance in aerodynamics, thermodynamics or process engineering. It enables precise predictions, deeper insights and targeted product optimisation without expensive physical tests.

What are the advantages of GPU-accelerated CFD?

GPU CFD significantly reduces simulation times and substantially lowers the cost per run. Thanks to massive parallelisation, GPU-based computation delivers more performance than classic CPU clusters – with lower investment and maintenance effort.

How do I specifically speed up my CFD runs?

In two ways: vertically with larger instances or dedicated servers for large meshes, horizontally with parallel runs for parameter studies – ten variants on ten instances instead of one after the other. The price calculator shows in advance what a study costs.

Why does cloud-based CFD make economic sense?

Operating your own CFD hardware is expensive to purchase, maintain and update. Cloud GPU solutions from centron offer predictable costs, flexible scaling and access to modern infrastructure – exactly when you need it.

How much does it cost to get started?

The starting prices are deliberately low: dedicated servers from €29.99 per month, Cloud GPU from €92.59 per month and S3 Object Storage from €5.00 per month. New accounts receive a €200 starting credit valid for 60 days – you can calculate the cost of your specific configuration transparently using the price calculator.

Which industries benefit most from using cloud GPUs for CFD?

Cloud-based CFD is suitable for companies in the automotive industry, aerospace, building technology, energy, infrastructure and research – wherever complex flows need to be simulated precisely.

Is using centron’s cloud resources complicated or time-consuming?

No. With centron you access powerful hardware directly, without set-up effort or maintenance. Use is simple, scalable and can be integrated into existing workflows.

How can I get started with cloud-based CFD at centron?

Contact our team or test our GPU cloud services directly. We advise you personally and help you move your CFD processes to the cloud.

Does centron offer servers for rent – and which variants are there?

Yes, at centron you can rent powerful server solutions as needed: ccloud³ VMs are quick to launch and flexibly scalable, with managed servers centron takes over operation and maintenance, and dedicated servers provide exclusive hardware for large meshes.

Can this be implemented in a way that complies with the GDPR?

Yes. Simulation data rarely contains personal references, but regularly contains trade secrets – flow models allow conclusions about product development. At centron, input data and results remain in Germany, without third-party access. Operations take place in data centres certified to ISO 27001 based on IT-Grundschutz; for ccloud³ / Managed Cloud there is an unqualified BSI C5:2020 Type 1 attestation. Details can be found in the Trust Center.
