Abstract
This paper presents the integration of simplification and idealisation of the geometry definitions of FE (Finite Element) models during the various steps of a FEA (Finite Element Analysis). This integration is performed using a polyhedral representation of a part which allows the engineer to perform all transformations required to adapt the geometric support of the model. These transformations are carried out through a vertex removal process which is monitored using geometrical and mechanical criteria. These criteria based on the analysis of the FE model provide interactive (through an a priori user definition) or automatic (through an a posteriori error estimator) management of geometry transformations. This approach is illustrated through two examples: the first one is based on an interactive a priori adaptation, and the second one is based on an automatic a posteriori adaptation.
