2 Introduction This presentation demonstrates how the SimDesigner Gateway easily enables the use of CATIA solid models as the basis for structural finite element models by transferring node, element and boundary condition data from CATIA to a standard MSC Nastran data file. 2

3 CAD to FEA Data Transfer Methods IGES or STEP Transfer Mesh and boundary conditions do not transfer Design iterations require FEA model reconstruction CAD/FEA Integration and Connection Products Preprocessing capabilities are often inadequate Solution options and controls are often limited? SimDesigner Mesh and boundary conditions stay with CATIA solid model throughout analysis process Standard Nastran deck output is versatile for preprocessing and solution 3

19 Conclusions SimDesigner Gateway enables users to conveniently and efficiently transfer finite element model data from CATIA solid models to a Nastran output file. CAD model changes are easily reflected to the FEA model. SimDesigner is integrated into the CATIA GUI while enabling user control of preprocessing and solution in Nastran. 19
