Finite element results deviate from physical test by up to 30 per cent, and agreement within 5 per cent is considered very good. Accuracy rests on mesh quality, boundary conditions and material data, not on which software you happen to own. A wrongly built model does not fail visibly, it produces a confident and entirely plausible answer.
You never validate your own work in isolation. The engineers to worry about are not the ones who make mistakes, but the ones with no second method to catch them.
