The basic principles of validation, verification and review described in Step 7 of the design methodology (link) should be followed and recorded.

For finite element modelling of the structural behaviour the following specific points should also be addressed when considering the validation and verification of the complete design.

• Compared to the scoping study are the results expected?
• Has the software been validated against available test results?
• Are the assumptions and approximations embedded within the software fully understood?
• Has numerical failure occurred?
• Has the mode of failure been identified?
• How has localised failure been considered?
• Can the analysis be conducted using alternative software to check the results?
• Are boundary conditions realistic?
• Has a sensitivity analysis relating to the mesh density been carried out?
• Has the stress-strain-temperature relationship for various materials been correctly used?
• Has strain reversal been included?
• Has input data been checked?
• Have various fire scenarios been considered to define the worst case structurally?
