Abstract
We developed an automatic mesh generation system (FORTUNA) for crash simulation of a car body by using Feature Recognition Technology and Mesh Generation Technology. It creates such mesh as those created by skilled operators in a batch job. All procedures are carried out in full automatic with the feature recognition function, which enables FORTUNA to determine features as if by the human eyes, the mesh generation to suit each feature, and the mesh quality optimization. Applying to a Japanese automobile manufacturer, we had the excellent mesh results that require almost no manual mesh modification. As a result, FORTUNA is evaluated as the operator-friendly system that removes the burden of the menial mesh modification work.
