Computer Aided Design (CAD)

Computer Aided Design (CAD) and Computer Aided Engineering (CAE) are two significantly
different disciplines, and hence they require different shape models representations. As a result, models
generated by CAD systems are often unsuitable for Finite Element Analysis (FEA) needs. In this paper, a
new approach is proposed to reduce the gaps between CAD and CAE software’s. It is based on new shape
representation called mixed shape representation. The latter simultaneously supports the B-Rep
(manifold and non-manifold) and polyhedral representation, and creates a robust link between the CAD
model (B-Rep NURBS) and the polyhedral model. Both representations are maintained on the same
topology support called the High Level Topology (HLT), which represents a common requirement for
simulation model preparation. An innovative approach for the Finite element simulation model
preparation based on the mixed representation is presented in this paper, thus a set of necessary tools is
associated to the mixed shape representation. They help to reduce the time of model preparation process
as much as possible and maintain the consistency between the CAD and simulation models

Finite element analysis (FEA)

is an exciting engineering solution that digitally predicts and simulates material behavior under defined conditions. Using build material information and accurate 3D models of a part or assembly, FEA predicts structural or performance problems before they occur in the real world.

FEA is a powerful tool for automobile, aerospace, shipbuilding, and construction industries. It addresses engineering challenges with accurate, timely and cost-effective solutions. Pinnacle Technology Service’s structural, flow, and FEA analysis services are delivered using industry-standard tools such as Ansys, HyperWorks, and Lsdyna.
