Engineering Simulation Software Validation & Procurement Guide

Technical fit

• Define the physics, nonlinearities, operating ranges, material models and coupling needed for the intended engineering decisions.
• Document solver assumptions, mesh or discretization controls, convergence criteria and sensitivity checks required by the team.
• Separate ease of use from evidence that a model is appropriate for the decision being made.

Verification and validation

• Use benchmark problems, hand calculations or trusted reference cases to verify implementation and setup.
• Compare predictions with experimental or field evidence when model validation is required.
• Keep assumptions, calibration, version and input data traceable so results can be reproduced and reviewed.

Procurement and governance

• Compare licensing, compute, support, training, automation and data-exchange costs across the expected workflow.
• Test CAD import, scripting, batch execution, reporting and result export with representative models.
• Define software-version qualification and change-control rules for regulated or safety-significant workflows.
