These are hypothetical scenarios with explicit assumptions. They do not establish equal capabilities, measured usability or a negotiated price.
| Requirement | Proposed exercise | Accept when |
|---|---|---|
| Flow reference | Prepare an authorised reference flow case with specified physical properties. | The engineer can explain the model and independent expected behaviour. |
| Mesh and boundaries | Inspect the mesh, boundary conditions and selected physical models. | The setup represents the intended problem and its modelling assumptions. |
| Result verification | Review conservation, convergence and a suitable sensitivity check. | The engineer can explain the result checks and remaining uncertainty. |
| Operating configuration | Record software version, solver, compute and required licences or support. | The team can reproduce and maintain the approved analysis environment. |

Scope and architecture
CFX and Simcenter STAR-CCM+ should be compared through the specific flow problem and engineering workflow. Test the required physics, meshing, numerical configuration and outputs, including the exact application and compute entitlements.
A CFD product name does not establish the physical models, solver choices or validity of an analysis. Define the flow problem, geometry, mesh, turbulence or other required models, boundary conditions and outputs. OpenFOAM distributions and releases must be identified explicitly; commercial application and HPC entitlements also vary.

Cost and migration planning
For Ansys CFX, include selected solver licence, HPC options, hardware and support. For Simcenter STAR-CCM+, include selected application licence, compute, deployment and support. Use the same workload and resilience assumptions, then confirm current vendor terms for the selected configuration.
Validate a copied reference case against independent expectations and retain its geometry, mesh, physical properties and settings. Record the selected distribution or application release, numerical method and post-processing procedure before replacing an established analysis.
