A CAD-Integrated System for Automated Idealization of CAD-Models for Finite Element Analysis Available to Purchase

The work described in this paper seeks to minimize the time spent on manually reducing thin-walled CAD-geometry into surface idealizations. The purpose of the geometrical idealizations is the creation of shell element meshes for FE-calculations. This is motivated by time and thereby cost savings and also to make the results of the calculations available earlier in the product development process allowing the results to guide the designs to a larger extent. Systems for automated geometry idealization and creation of FE-models already exist, but this paper describes a novel approach with the working principle of analyzing how the CAD-specific features of the CAD-file history tree are constituted. This information is used to automatically create the best practice geometrical idealization in the same CAD-model. Evaluation of the performance of the system in an industrial example is also presented.
