FEA performance with ease-of-use

Femap is recognized as the world’s leading CAD-independentWindows-native pre- and post-processor for advanced engineeringfinite element analysis (FEA). It provides engineers and analysts with an FEA modeling solution to handle even the most complex tasks easily, accurately and affordably.

Femap has embodied the principles of power and simplicity for over 20 years and continues that focus today with a new Microsoft Office-compatible graphical user interface, which streamlines workingprocesses and access to all Femap functionality.

As an engineer, you demand software that is not only cost effective and easy to use, but with the power to model the toughest problem. Femap delivers just that – affordable high-performance FEA modeling for the engineering desktop withWindows-native ease-of-use.

Benefits of Femap’s Windows-native user interface include:

• Work with multiple analysis models in the same session, use multipleviews per model

• “Cut and paste” from one model to another

• Easily manipulate higher level entities such as load and constraint setswith the model information tree

• Review and edit Femap model data with the entity editor, copy and paste information between Windows applications

• Use the data table to sort, group and edit model data using aconvenient grid-based tabular representation of Femap model data

• Select Femap entities from the top level of the interface using the fullycustomizable toolbar interface

• Leverage the value of a common Windows-native implementation.Femap features a complete set of standard toolbars together withseventeen fully customizable, floating dockable toolbars.

The modern Windows-native user interface provides a flexible and customizable analysis environment for structural, thermal, CFD and in-house applications.

CAD-independent

Serious engineering in a Windows 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-independent analysis environment.

Femap provides exceptional value and performance and is not limited to geometry-based digital data. Femap will also delight customersworking with pure finite element model data. As a nuts-and-bolts,“bottom up” finite element pre- and post-processing solution, Femapprovides a range of FEA model readers to rapidly import existingmodels from many FEA solvers. Advanced functionality then easesmanipulation of finite element data 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 or complex systems.

CAD-independentFemap offers seamless geometry access with major CAD systems such as Pro/Engineer, Catia, NX, I-deas® NX Series software, Solid Edge®

software, AutoCAD and SolidWorks. Based on the industry-standardParasolid geometry engine, Femap offers extensive geometry creationtools including standard wireframe curves, surface and solid modeling.Powerful shelling, blending, Booleanoperations, surface imprinting and lofting combine to make Femapextremely effective at creating geometry for analysis.

A better mesh, faster than everWith intelligent default mesh sizing, Femap anticipates your meshingrequirements. Femap also provides flexible mesh controls on points,curves and surfaces, with extensive options for biasing and control of mesh topology, plus fully automatic, high-speed tetrahedral solidmeshing and quad-dominant surface meshing.

The right geometry for analysisEngineers often encounter geometry that is not ideal for analysismodel definition. Femap provides geometry creation and editing toolsfor curves, 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 improvemeshing areas for higher quality shell meshes.

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

Analysis set managerThe analysis set manager in Femap allows you to store solver setup data with your models, so you don’t need to complete numerous dialog boxes each time you edit your model and create a 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.Nastran,Abaqus,Ansys, MSC.Marc, LS-DYNA, SINDA and TMG. Femap providesthe ability to re-use and integrate analysis models from legacy data andfrom customers and suppliers. Femap’s complete element library, withcomprehensive support of physical and material definitions, takes fulladvantage of the advanced capabilities of these solvers, includingdynamic, geometric and material nonlinear applications.

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

Integrated multi-physics solvers for Femap

Femap Thermal Femap Thermal includes both the transient andsteady-state thermal analysis capabilities required to solve the majority of common engineeringproblems. Capabilities include the modeling ofconduction, convection, radiation and phase change.Femap Thermal provides a range of thermalboundary conditions and solver controls andprovides a powerful thermal modeling tool forassemblies. This thermal coupling capability allowsusers to create paths for heat to flow between parts in large, complex assemblies.

Femap Advanced ThermalFemap Advanced Thermal adds many advancedthermal and fluid flow modeling capabilities to theFemap Thermal package. For example, fluid duct flow modeling includes coupled convection and fluid flow analysis. An extensive set of tools foradvanced radiation and spacecraft modeling includes solar and orbital heating, orbit modeling and display, specular reflections with ray tracing and articulating structures.

Femap Advanced Thermal also includes advancedsolver features such as custom user subroutines,model simplification, substructuring and interfaces to industry thermal codes.

Femap FlowFemap Flow provides a comprehensive 3Dcomputational fluid dynamics (CFD) solution fully integrated within Femap.When combined with Femap Advanced Thermal, it solves a wide range of multi-physics problems that involve fluid flow and heat transfer. Both low-speed and high-speed compressible flows can be modeled. The Femap Flow solver uses an efficient and robust element-based finite volume, multi-grid solver to compute 3D fluidvelocity, temperature and pressure for both steady-state and transient applications.

Forced flow, natural convection and mixed flows can be modeled with multiple inlets, outlets andinternal flow boundary conditions. For electronicscooling applications, the package easily models fan curves, inlet and outlet resistances as well asconvection from thin structures. Rotating systems, moving walls, flow turbulence models, humidity and other features are available for the most advanced fluid flow modeling requirements.
