Real FEA made easy
Femap is an advanced engineering simulation software program that creates finite element analysis models of complex engineering products and systems, and displays solution results. Femap can virtually model any type of components, assemblies or systems and determine the behavioral response for any given operating environment, with total control of the FE model.
Very useful for early concept model development, prior to detailed CAD model availability. Femap had the ability to generate simple geometry quickly and efficiently for FE modeling. Geometry preparation prior to FE model creation is typically a laborious and time consuming task, so any process improvements can realize significant benefits and allow faster and more accurate FE model creation.
CAD-IndependentFemap is CAD-independent and can access geometry data from all major CAD systems such as CATIA, Creo, NX, Solid Edge, SolidWorks, HiCAD and Inventor. Once imported you can prepare the model for analysis using the geometry locator to identify and display potentially troublesome entities, such as slivers, and either remove them completely with the geometry cleanup tools or suppress them. Femap also offers a wealth of geometry creation and modification functions so you can make necessary model changes in preparation for finite element model creation.
Solver NeutralFemap is solver-neutral and provides in-depth pre- and postprocessing support for all of the main commercial solvers on the market, including NX Nastran, Ansys, LS-DYNA, Abaqus and TMG. You can take full advantage of the advanced analysis capabilities of these solvers using Femap’s comprehensive modeling and analysis support, particularly for dynamic, geometric and material nonlinear, heat transfer and fluid flow analyses.
Beam ModelingBesides solid and shell element models Femap also supports beam modeling and meshing. This technique allows models comprising long, slender components to be represented by one-dimensional elements with associated properties.
Model visualization is key to beam modeling, and with Femap you can view these elements as solid components and include offsets. Femap features a section property editor which includes a library of standard cross-section shapes. You can also define your own sections, and the built-in section property calculator automatically determines the required properties.
PostprocessingA wealth of visualization capabilities help you view and interpret the results to quickly understand the model behavior. You’ll find everything you need to view and interpret the output data, including:
- Contour and criteria plots
- Deformed shape animations
- Dynamic cutting plane and iso-surfaces
- Full output selection
- XY plots
- Free body diagrams and grid point force balance output
- Time and frequency domain animations
Complete access to results data is provided through the Data Table pane, which you can use to gather, sort and control the amount and type of data that is visible, to compile an analysis report.
Finite Element MeshingFemap’s 3D solid and surface meshers are tuned to generate high-quality meshes, providing well-shaped elements to ensure accurate results. Femap gives you full control over all mesh generation parameters including mesh sizing, meshing of small features, growth factors, short edge suppression, etc. With complex geometry, modification of the mesh is often required in areas where greater accuracy is desired. For this situation Femap’s Meshing Toolbox allows you to interactively modify mesh sizing parameters on the underlying geometry, and see the mesh update automatically. You can also view element quality feedback live while modifying the mesh, to ensure that a high-quality finite element model is created.
Composite ModelingThe use of composite materials in designs has increased significantly in recent years, and Femap can help you model and postprocess results on composite structures. With Femap’s a laminate editor and viewer, you can update the laminate properties interactively as you create and modify plies in the laminate.
You can also postprocess composite laminate results using Femap’s global composite ply feature, which allows you to view results on continuous plies through the structural model.
