The automatic generation of representative fuselage section models with a detailed discretization for the application in computer-aided transient dynamic simulations in the aircraft pre-design process chains is described in this paper. The process consists of Python routines to select and reduce the section from the full fuselage and to refine the mesh and extrude crosssections in arbitrary zones of the section. By this, different mesh qualities can be integrated in the model according to its individual application. These functionalities were integrated in the structural modelling and sizing framework PANDORA. A simple reinforced panel was used to investigate its structural behaviour with different discretization options under a bending loading condition. Also, a fuselage section model reinforced using either one of the discretization options was subjected to a quasi-static loading. The model was then simulated under crash conditions to investigate its non-linear structural behaviour. The focus of this paper lays on the application and the local structural analysis of the detailed fuselage section in water impact simulations.  \n1. Introduction  \nAccurate predictions in early aircraft design stages contribute to the assessment of different concepts, by this supporting the development of novel aircraft designs. Alongside top-level aircraft requirements including flight range, performance, and fuel consumption, assumptions regarding structural aspects must be complied according to certification requirements. To include all disciplines in the development of a novel model a multidisciplinary design process chain is required. An iterative and efficient approach in terms of cost and time is done by using a virtual process chain with different computer-aided tools, each dedicated to the generation of specific disciplinary inputs. Different structural design tools like PrADO (Preliminary Aircraft Design and Optimization) [1] or MIDAS (Multidisciplinary Interactive Design and Analysis System) [2] are found in the academic and research field. Applications like LAGRANGE [3] or FAME-W (Fast and Advanced Mass Estimation-Wing) [4] are used in the industry. Other multidisciplinary structural tools are described in more detail e.g. in [5] .  \nThe structural design must also be compliant to crashworthiness requirements. Besides the investigation of the aircraft for certain crash loading conditions, the aircraft manufacturer must demonstrate the behavior of the airframe in the case of a planned emergency landing on water, known as ditching. This event is characterized by high hydrodynamic loads at the impact and the presence of hydrodynamic phenomena during landing, which may affect the structural integrity and the kinematics of the aircraft resulting in decelerations experienced by the occupants. Ditching can be analyzed with experimental tests with sub-scale models, by comparisons with previous certified aircraft using  \nContent from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.
