Best-in-class digital simulationWhy digital simulation?Industry pressure to reduce costs andimprove quality is driving growth inthe use of digital simulation throughout the product lifecycle. Choosing theright tools is key to achieving the business benefits of digital simulation.Why Femap?Siemens PLM Software’s Femap system facilitates an advanced engineering analysis environment. CADneutral and solver-neutral technologyand cost-effective functionality haveenabled Femap to become the world’smost popular engineering analysisenvironment for Nastran users. It iswidely used by the world’s leadingengineering organizations and consultants to model complex products,systems and processes, includingsatellites, aircraft, defense, automotivevehicles, electronics, heavy construction equipment, lift cranes, marinevessels and process equipment.Femap and NX Nastran softwareare highly integrated and can be soldtogether as a bundled solution. Butmore than this, being open to all solvers, Femap demonstrates the powerand value as a core analysis tool.Femap is CAD independent andleverages Siemens PLM Software’sParasolid modeling kernel that allowsdirect access to Parasolid data forsurface and solid modeling in additionto advanced geometric tools necessaryfor accessing non-Parasolid geometry.2From advanced beam modeling, midsurface extraction and hex meshing torobust CAD import and idealization,Femap gives you unparalleled modelcontrol and flexibility with a broadrange of loads, materials, analysistypes and visualization options.Femap is not just a solid investmentfor those committed to excellence inthe use of finite element analysistechnologies. It’s the right tool to helpyou realize your business goals.Your business benefits Faster to market with innovativenew products Lower cost through less physicalprototyping, fewer engineeringchange orders and better in-servicewarranty Increased product quality

With powerful tools easing allaspects of the creation, manipulation andreview of an engineering analysis model,Femap is the natural choice for a completeCAD-independent analysis environment.Femap provides exceptional value andperformance and is not limited to geometry-based digital data. Femap will alsodelight customers working with pure finiteelement model data. As a nuts-and-bolts,“bottom up” finite element pre- and postprocessing solution, Femap provides arange of FEA model readers to rapidlyimport existing models from many FEAsolvers. Advanced functionality then easesmanipulation of finite element data at thenode and element level.6The bottom line is that Femap makes itpossible to quickly create models thataccurately predict the structural, dynamicand thermal performance of single components, assemblies or complex systems.CAD independentFemap offers seamless geometryaccess with major CAD systems suchas Pro/Engineer, Catia, NX, NX I-deas software, Solid Edge, AutoCAD andSolidWorks. Based on the industrystandard Parasolid geometry engine,Femap offers extensive geometry creationtools including standard wireframe curves,surface and solid modeling. Powerfulshelling, blending, Boolean operations,surface imprinting and lofting combineto make Femap extremely effective atcreating geometry for analysis.

Assembly modelA better mesh, faster than everWith fully automatic, high-speedtetrahedral solid meshing and quaddominant surface meshing technology,Femap creates fast and accurate mesheseasily and reliably. You can also takeover full control and work interactivelywith Femap to manipulate the mesh orunderlying geometry, while viewing element quality feedback live.The right geometry for analysisEngineers often encounter geometrythat is not ideal for analysis model definition. Femap provides geometry creation and editing tools for curves, surfaces and solids, feature suppression andmid-surface extraction. Solids can besubdivided and automatically connectedto represent dissimilar materials or tofacilitate semi-automatic hexahedralmesh generation. Engineers cancombine multiple surfaces to improvemeshing areas for higher qualityshell meshes.Automatic assembly management“The significant meshing enhanceFemap can automatically detect compoments for hexa-elements in Femapnents of an assembly that are in contact. helped our productivity to increaseThe method of connection, whetherby 30 percent or more. Even forglued or contact (linear and nonlinear) is difficult shapes, Femap performseasily specified allowing rapid setup forwell. Without requiring a compliassembly models.cated operation, a good qualitymesh can be obtained.”Yuka FukunagaAnalysis Technology Research CenterSumitomo Electric Industries7

Directly from the Femap user interface, you can access the OLE/COMobject-oriented Femap application programming interface (API) that providesdirect access to all Femap objects andfunctionality. The BASIC engine is fullyOLE/COM compliant and can interfacewith Femap as well as any OLE/COMcompliant program such as Word orExcel. You can create custom programsthat automate repetitive tasks, searchmodel or results data, or programs thattransfer model information to Word orExcel to create customized reports.These powerful customizationcapabilities allow complete access toFemap full functionality throughstandard nonproprietary programminglanguages, and maintain Femap as theindustry’s premier independent andopen engineering environment.Macro program filesIn addition to the API programming capability, Femap hosts a Program File capability in its own Femap window. Userdefined macros can be recorded, edited,debugged, and played back all within theFemap interface.Many useful programs are delivered withFemap in an ever expanding library, andcan be found in the Custom Tools toolbarright in the user interface.9
