ABOUT EFFICIENT MODELLING OF THE GEOMETRY FOR FINITE ELEMENT ANALYSIS
Keywords:Efficient modelling of the geometry, minimal geometry, finite element analysis
The current CAD platforms provides to user a wide variety of powerful geometric modelling tools, which allows the generation with a high accuracy the 3D geometry of the machinery components. If for achieving the fabrication documentation, the accuracy of the geometry is undoubtedly indispensable, for finite element analysis this approach of the geometry modelling is not always recommended. In this context, after a brief presentation of the general framework of the issues approached, the article highlights the main aspects to be considered in modelling of the machinery and construction components geometry for efficient study of their behaviours using finite element analysis. Also is introduced the concept of minimal geometry as the foundation of efficient modelling of the geometry for finite element analysis. Next, a case study is presented, case study in which geometric modelling has followed the aspects enunciated. In final part of the article are presented some comments and conclusions.
