Tool for generation of analysis models by simplification of CAD model

The activity of design and mechanical analyses are in close connection. The increasing tendency to integrate these two activities, while guaranteeing the reduction of the simulation time, obliges us to carry out the analyses stage on adapted models to the objective of analyses. The latter are the results of the simplifications operations carried out on the original model. In this paper, we propose a tool for simplification of B-rep model mark, which makes it possible to generate the two models of predetermination and checking, while being based on a whole of identifying information of details that can be idealized. The developed tool is based on a hybrid method which uses two techniques: Removal of details and fusion of faces. In order to validate our tool, we have studied a set of mechanical parts, which shows the significant profit in computing times, all of them respect the precision wished for the results of simulation.
