Method for simulating a physical property of a technical structure by a component model

摘要

A method for simulating a physical property of a component model comprising a computer accessible construction model of a technical structure, by automatically generating a mesh of a component model. The component model is first described by a fine mesh of finite elements, and, based on the fine mesh, a fine natural frequency of the component model is determined. The component model is then described by a coarse mesh of finite elements, and based on the coarse mesh, a coarse natural frequency of the component model is determined. In this context, for example, the deviation of the coarse natural frequency from the fine natural frequency is used as a measure for the quality of the coarse mesh.
