CAD-independent

Serious engineering in aWindows environmentFemap delivers a depth of functionality normally only found in moreexpensive applications.With powerful tools easing all aspects of thecreation,manipulation and review of an engineering analysis model,Femap is the natural choice for a complete CAD-independentanalysis environment.

Femap provides exceptional value and performance and is not limited togeometry-based digital data. Femap will also delight customers workingwith pure finite element model data. As a nuts-and-bolts,“bottom up”finite element pre- and post-processing solution, Femap provides a rangeof FEA model readers to rapidly import existing models from many FEAsolvers. Advanced functionality then eases manipulation of finite elementdata at the node and element level.

The bottom line is that Femap makes it possible to quickly createmodels that accurately predict the structural, dynamic and thermalperformance of single components, assemblies or complex systems.

CAD-independentFemap offers seamless geometry access with major CAD systemssuch as Pro/Engineer,Catia,NX,NX I-deas® software, Solid Edge,AutoCAD and SolidWorks. Based on the industry-standard Parasolidgeometry engine, Femap offers extensive geometry creation toolsincluding standard wireframe curves, surface and solid modeling.Powerful shelling, blending, Boolean operations, surface imprintingand lofting combine to make Femap extremely effective at creatinggeometry for analysis.

A better mesh, faster than everWith fully automatic, high-speed tetrahedral solid meshing and quad-dominant surface meshing technology, Femap creates fast and accuratemeshes easily and reliably. You can also take over full control and workinteractively with Femap to manipulate the mesh or underlyinggeometry, while viewing element quality feedback live.

The right geometry for analysisEngineers often encounter geometry that is not ideal for analysis modeldefinition. Femap provides geometry creation and editing tools forcurves, surfaces and solids, feature suppression and mid-surfaceextraction. Solids can be subdivided and automatically connected torepresent dissimilar materials for semi-automatic hexahedral meshgeneration. Engineers can combine multiple surfaces to improve meshingareas for higher quality shell meshes.

Automatic assembly managementFemap can automatically detect components of an assembly that arein contact.The method of connection, whether glued or contact(linear and nonlinear) is easily specified allowing rapid setup for assemblymodels.

“The real value of simulation in aerospace is that youcould not do what we’re currently doing without it.Typical program schedules that used to take 5 yearsare now done in 2 years or 1 year.”

PROVEN VALUE

Integrating analysis technologiesLeading firms recognize that a single analysis technology seldom meetsall their requirements. By integrating multiple analysis technologiesin a single modeling and visualization environment with Femap, theycan make better design decisions faster.

Analysis set managerThe analysis set manager in Femap allows you to store solversetup data with your models, so you don’t need to completenumerous dialog boxes each time you edit your model and createa new analysis input file. The sets can also be saved in a library foruse with other models.

Multiple solver supportFemap provides in-depth, high-quality support for industry standardsolvers, including the popular and proven NX Nastran,MSC/MDNastran, Abaqus,Ansys, MSC.Marc, LS-DYNA, SINDA and TMG. Femapprovides the ability to re-use and integrate analysis models from legacydata and from customers and suppliers. Femap’s complete elementlibrary, with comprehensive support of physical and material definitions,takes full advantage of the advanced capabilities of these solvers,including dynamic, geometric and material nonlinear, heat transfer andfluid flow applications.

Leading third party solution providers use Femap to perform CFD, soilmodeling, advanced thermal analysis and electromagnetic simulations.

Fully customizable

Integrated BASICAPI Programming EnvironmentFemap offers a full-featured BASIC development environment in aseparate window. Directly from Femap’s user interface, you can accessthe OLE/COM object-oriented FemapApplication ProgrammingInterface (API) that provides direct access to all Femap objects andfunctionality. The BASIC engine is fully OLE/COM compliant and caninterface with Femap as well as any OLE/COM compliant program suchasWord or Excel. You can create custom programs that automaterepetitive tasks, search model or results data, or programs that transfermodel information toWord or Excel to create customized reports.

Many useful programs are delivered with Femap in an ever expandinglibrary, and can be found in the CustomTools toolbar right in theuser interface.

These powerful customization capabilities allow complete access toFemap’s full functionality through standard non-proprietary programminglanguages, and maintain Femap as the premier independent and openengineering environment.

Macro program filesIn addition to theAPI programming capability, Femap hosts a ProgramFile capability in its own Femap window.User-defined macros can berecorded, edited, debugged, and played back all within the Femapinterface.Macros to automate repetitive modeling tasks for example,can be created in an easy and straightforward manner.Once created,you can add these Macros to any Femap toolbar, providing powerfulautomation tools that are easy to produce, deploy and use.
