Structural and ThermalAnalysis WorkbenchesAbaqus for CATIA V5 functionality is grouped into twoCATIA V5 workbenches. Within the Structural Analysisworkbench, you define static, frequency extraction,or explicit dynamic simulation models, including allof the necessary mechanical attributes. Within theThermal Analysis workbench, you define heat transfersimulation models, including all of the necessary thermalattributes. Static and thermal simulations can be coupledtogether to determine the response of your model to acombination of thermal and mechanical influences.NonlinearityOne of the key features of Abaqus for CATIA V5 is itsaccess to the powerful nonlinear mechanics capabilitiesin Abaqus. These best-in-class capabilities have beena fundamental part of Abaqus from the beginning. Asa result, Abaqus for CATIA V5 simulations can includenonlinear geometric effects, such as arbitrarily largerotations and stress stiffening. These capabilities alsoallow nonlinear effects such as intermittent contact,plasticity, and temperature-dependent thermal filmconditions to be evaluated directly in CATIA V5.Frequency ExtractionNatural frequencies are often useful for assessing overallstiffness of a structure as well as likely deformationpatterns. Abaqus for CATIA V5 can calculate the naturalfrequencies either on the unloaded structure or on theloaded structure at any time within the simulationhistory. AFC’s ability to calculate the natural frequencieson a loaded structure can be important, because naturalfrequencies can change significantly during deformationas the structure experiences changing loads, boundaryconditions, temperatures, and contact conditions.Dynamic Analysis Within Abaqus/ExplicitExplicit dynamic analysis is well-suited for large modelswith relatively short response times and for the analysisof extremely discontinuous events, such as impact. Verygeneral contact conditions can be modeled, includingcontact between many or all regions of the model, with asingle interaction definition.Abaqus for CATIA V5 allows users to leverage the power of provenanalysis technology to evaluate and improve their designs.ContactSubmodelingAbaqus for CATIA V5 provides two powerful techniquesfor modeling contact. You can either define pairs ofcontact surfaces yourself with the aid of the “FindInteractions” wizard, or you can let Abaqus automaticallydetermine the contact regions using the Abaqus “GeneralContact” approach. Either approach enables modelingof complex multipart interactions in assemblies.Components can experience large relative sliding, whichcan include friction effects. It is even possible to captureself-contact effects, such as when a surface deformsso severely that it folds over onto itself. For thermalsimulations, gap heat conductance properties can beassigned to contact surfaces so that the surfaces conductheat appropriately, depending on the size of the gap andthe temperature at each surface.Once you have obtained analysis results for a model,you can use submodeling to rapidly study a local regionwith greater geometric detail and a more refined mesh.Performing a submodel analysis is a two-stage process.First, you create and analyze the global model. Youthen create the submodel and drive the boundaries ofthe submodel with results that were saved during theanalysis of the global model. You can apply submodelboundary conditions in both mechanical andthermal steps.Loads and Boundary ConditionsIn Abaqus for CATIA V5 you can apply loads andboundary conditions using time-varying amplitudedefinitions to enable the highest degree of control overloads and constraints. Numerous types of loads andconstraints are available, including rigid constraintsthat enable you to define selected parts or regions ascompletely rigid in the specified degrees of freedom.MaterialsAbaqus for CATIA V5 allows you to use linear materialproperties defined in the CATIA V5 material library.You can extend these materials to include nonlinearproperties or create entirely new Abaqus materialproperties and store them conveniently in the CATIAV5 material library. The materials can be temperaturedependent and include thermal material properties, suchas thermal conductance and specific heat.

You also have access to theversatile Abaqus C3D10I tetrahedral elements foraccurate contact and plasticity results. CATIA V5surface meshing tools enable you to create triangle- orquadrilateral-dominated shell meshes. A single modelcan combine different element types.Component assemblies can use a variety of connectionmethods such as bolts, springs, or welds. The boltmodeling capability enables easy modeling of boltedconnections to simulate bolt loads accurately. The spot,seam, and surface weld modeling tools enable you tomodel a large number of flexible or rigid fasteners in justa few steps. Other types of available connections arerigid connections, virtual parts, and nonlinear springs.Job ManagementPostprocessingIntegrated job management enables you to create jobspecifications, write input files, and monitor progress.Specifications may be detailed and include file storagelocations and memory settings. After submitting analysisjobs, the ability to continuously monitor solutionprogress allows the prompt receipt of any warning orerror messages from Abaqus.As a fully integrated CATIA V5 solution, Abaqus forCATIA V5 provides access to the extensive CATIA V5postprocessing capabilities, including useful tools such ascutting plane visualization. Through the Abaqus outputdatabase, you also have access to the extensive set ofavailable Abaqus output variables, providing a wide rangeof results visualization capabilities.Realistic Simulations provides confidence in makingcritical performance-based decisions faster.

Concurrent Engineering with Analysis AssemblyAnalysis assembly enables creating assemblies by combining existing finite element analysis documents. With thistechnique companies are encouraged to create libraries of high-quality parts and sub-assemblies—including their finiteelement meshes and connections—that can be reused in multiple analysis scenarios, enabling greater efficiency and abetter collaboration.Different users can create the finite elementmeshes and connections for parts and sub-assemblies.A master analysis model can be assembled fromexisting part and sub-assembly finite element models.Iterative and Collaborative Design LoopAbaqus for CATIA V5 is an effective tool for deploying proven analysis workflows across the enterprise.
