STEFAN TABACU, ANTON HADĂR, NICOLAE DORU STĂNESCU, SORIN ILIE, DANIELA IOANA TUDOR HEXAHEDRAL FINITE ELEMENTS MESH GENERATION METHOD WITH APPLICATIONS TO PLASTICS PARTS Most of the problems of modern engineering are solved using numerical methods. In order to use a numerical method the first step that must be performed is to generate a numerical model that contains all the input data in terms of geometry, material data, boundary conditions (loads and support). Ideally a structure must be defined only using hexahedral elements that are capable to provide the best results. This paper presents a method for generation a fully hexahedral finite elements model using a grid based procedure. The method is a good support for the engineering involved in product design. An application to a plastic manufactured part is presented. The results obtained using the all hexahedral finite elements models are compared with the results obtained using a numerical model generated using conventional techniques.
