CFD X is the cloud-hosted edition of Simcenter STAR-CCM+. The same solver and the same workflow as on-prem, but run on Siemens-managed compute — sized to your job rather than to your fixed cluster.
Why customers move to cloud CFD
- Burst capacity — peak demand without paying for cluster capacity that sits idle the rest of the year.
- Latest hardware — cloud nodes refresh on Siemens’ schedule, not yours.
- Predictable per-job cost — pay for what you run, not what you might run.
- Distributed teams — no VPN and licence-server gymnastics.
When on-prem still makes sense
- Continuous high utilisation where reserved cluster economics beat per-job cloud pricing.
- Strict data-residency or air-gap requirements.
- Existing investments in cluster hardware that haven’t yet amortised.
