Nevertheless, the costs are still very high, so that further improvements are crucial. In this work, the concept of the continuous and the discrete adjoint method are applied in structural dynamics. Additionally, a modified discrete method, which is independent of the time discretization of the primal problem, is proposed. This approach results in further numerical savings, while the quality of the gradient does not suffer.enEngineering and Applied OperationsConference Paper10.1007/978-3-031-50000-8_5Nachbagauer, KarinKarinNachbagauerHeld, AlexanderAlexanderHeldConference Paper
