==CAE in the automotive industry==
CAE tools are widely used in the [[automotive industry]]. Their use has enabled automakers to reduce product development costs and time while improving the safety, comfort, and durability of the vehicles they produce. The predictive capability of CAE tools has progressed to the point where much of the design verification is done using computer simulations (diagnosis) rather than physical [[prototype]] testing. CAE dependability is based upon all proper assumptions as inputs and must identify critical inputs (BJ). Even though there have been many advances in CAE, and it is widely used in the engineering field, physical testing is still a must. It is used for verification and [[Finite element updating|model updating]], to accurately define loads and boundary conditions, and for final prototype sign-off.
