A Study on the Effect of Simplification Techniques of CAD Models used for Finite Element Simulations

Authors(2) :-Subash Karan. R, Ravichandran. R

Now days, simulation plays a major role on product development section in industries. In recent the simulation is currently used in design, dimensioning and analysing of the mechanical parts. We focusing on the dynamics of the microscopic world and on realizing simulations that capture maximum complicity using minimum computation time and cost. FEM becomes the most useful approach in simulation of mechanical behaviour. For that it requires initial CAD model. It is not easy to analyse complex models. So, it is necessary to simplify the models before simulation. In this paper presents an automatic CAD model suppression approaches. First part of this paper deals with a Rule based approach to simplify the features for that the rules are generated with help of expert’s knowledge and suppression has obtained in Knowledge ware a special tool available in CATIA V5. Second part presents a Hybrid method approach to simplify CAD model. The implementation of algorithm on Open Cascade Platform is also presented. Finally estimate the effect of using this approach on CAD model. It shows that computational time is reduced with minimal changing the exactitude of results.
