Claim One:
1. 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 the component model, said method comprising: using CAD data to describe the component model by means of a fine mesh of finite elements; based on the fine mesh, determining at least one fine natural oscillation of the component model, comprising at least one of a fine natural frequency and a fine natural oscillation mode; describing the component model by means of a coarse mesh of finite elements; based on the coarse mesh, determining at least one coarse natural oscillation of the component model, comprising at least one of a coarse natural frequency and a coarse natural oscillation mode; as a measure for the quality of the coarse mesh, using a deviation of the coarse natural oscillation, comprising at least one of the coarse natural frequency and the coarse natural oscillation mode, from the fine natural oscillation, the fine natural frequency and the fine natural oscillation mode; describing the component model iteratively by increasingly coarser meshes, beginning from the fine mesh, until the deviation of a current coarse natural oscillation from the fine natural oscillation exceeds a threshold value; and automatically aborting said generating of the mesh of the component model when the threshold value is exceeded, wherein the increasingly coarser mesh which is used to describe the component model at the point when the threshold value is exceeded is used for said simulating the physical property of the component model.
