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.
