The Finite Element Method (FEM) has been an integral part of all phases of the car, body and component development process in ŠKODA AUTO a.s. In the early stages of development, it replaces and simulates real-world testing and allows for a large number of design variants to meet many often conflicting requirements. The constantly increasing capacity of computing clusters enables parallelization not only to manage the constantly increasing number of calculations, but also to describe the behavior of the virtual model in still greater detail. The lecture redefines the philosophy of use (FEM) in vehicle body design and an overview of the computational portfolio that covers not only static stresses but also a large number of crash tests that today's modern cars are subjected to. The basic modeling methodologies will be mentioned, as well as the current trends for describing the processes occurring in the structure of a car in dynamic impact tests, which are related, for example, to material violations.
