“…A CAD model, however, has sharp edges, and the triangle mesh it generates is not dense, and is irregular. When mesh-based methods are applied to a CAD model, the shape may be distorted (Gao et al, 2010).…”

“…Different application domains' requirements lead to a wide variety of feature definitions. In CAE applications, the focus has been set on removing detail features to simplify models before meshing [4,8]. A particular domain, mostly studied in the 80-90s is the recognition of machining features.…”

Abstract. Shape idealization transformations are very common when adapting a CAD component to FEA requirements. Here, an idealization approach is proposed that is based on generative shape processes used to decompose an initial B-Rep object, i.e. extrusion processes. The corresponding primitives form the basis of candidate sub domains for idealization and their connections conveyed through the generative processes they belong to, bring robustness to set up the appropriate connections between idealized sub domains. Taking advantage of an existing construction tree as available in a CAD software does not help much because it may be complicated to use it for idealization processes. Using generative processes attached to an object that are no longer reduced to a single construction tree but to a graph containing all non trivial construction trees, is more useful for the engineer to evaluate variants of idealization. From this automated decomposition, each primitive is analyzed to define whether it can idealized or not. Subsequently, geometric interfaces between primitives are taken into account to determine more precisely the idealizable sub domains and their contours when primitives are incrementally merged to come back to the initial object.

“…Gao Shuming presented a framework to CAD mesh model simplification based on feature suppression. The approach is capable of removing unnecessary form features from the mesh model without any changes to the rest part [5].

Current parametric parts library cannot contribute to the reuse of finite element model. It is essential to remodel or exchange model for parts in CAE software. This paper presents a synchronous CAD/CAE modeling method, which can be employed in parts library based on Siemens NX software. Primary CAD and CAE information in part are merged into master model, which acts as cornerstone for solid model, FE model and simulation model. Thus, part models from parts library can be directly used into simulation analysis, and parametric amendment and change propagation is sustained. A software package developed for designers is helpful to search and achieve desired part from parts library. Three case studies are carried out to clarify synchronous CAD/CAE modeling process and change propagation procedure.
