This is an example of an issue previously raised by CROSS and others about the problems of validating the software model and verifying the output.
The advice is to check results, possibly using more than one software package, and check that the computer aided design is to the relevant codes of practice. Designers must remember that it is they, not software suppliers, who are responsible for design.
