These are hypothetical scenarios with explicit assumptions. They do not establish equal capabilities, measured usability or a negotiated price.
| Requirement | Proposed exercise | Accept when |
|---|---|---|
| Reference model | Rebuild an authorised small reference model with known assumptions. | The responsible engineer can reconcile model definitions and expected behaviour. |
| Material and loads | Inspect the selected materials, constraints and load cases. | The model includes the intended definitions and documented limitations. |
| Numerical review | Review meshing, solver configuration and a suitable sensitivity study. | The engineer can explain the chosen numerical settings and result checks. |
| Licence scope | Record the application, solver, modules and execution rights used. | The quoted configuration supports the intended analysis and operating arrangement. |

Scope and architecture
COMSOL and Simcenter 3D provide different routes to engineering simulation. COMSOL scope depends on its selected physics modules; Simcenter 3D scope depends on the chosen applications and solvers. Match the physical problem and model-validation process before comparing costs.
Match the physical problem, analysis type, material model, solver, meshing and required output. These are engineering applications, not an independent approval of a physical design. The selected modules and solver entitlements matter more than the vendor’s complete portfolio.

Cost and migration planning
For COMSOL Multiphysics, include base licence, required modules, deployment and compute resources. For Simcenter 3D, include selected application and solver licences, modules, compute and support. Use the same workload and resilience assumptions, then confirm current vendor terms for the selected configuration.
Rebuild a small authorised reference case, preserve material and boundary-condition definitions, and compare results against independently specified expectations. Have the responsible engineer approve the validation and operating procedure before moving a production analysis.
