Abstract The integration of CAD information and Finite Element Analysis is one of the important problems addressed by the design automation requirements. In case of parts involving free-form surfaces, the creation and adaptation of a mesh are still one of the bottlenecks attached to the search for competitive design. A solution is proposed which inserts a mesh adaptation software into the CAD-FEA chain. Full geometric data of free-form surfaces is used as input together with an initial approximate mesh. Geometric and mesh information on their own, as well as together, use extensively the concept of classification introduced here. Furthermore, topologically and geometrically layered adaptation tools are provided which achieve radaptivity, mesh coarsing, mesh refinement and edge swapping treatments. The toolkit thus available is demonstrated on examples and its integration requirements are all developed along its description.
