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.
Femap is CAD-independent and can access geometry data from all major CAD systems including CATIA, Pro/Engineer, NX, Solid Edge, SolidWorks, HiCAD, Inventor and AutoCAD. 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.
Femap is solver-neutral and provides in-depth pre- and postprocessing support for all of the main commercial solvers on the market, including NX Nastran, MSC 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.
A 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
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 Meshing
Femap’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.
Femap integration with NX Nastran
Femap has a 20 year history of working as a pre- and post processor to Nastran. In addition to NX Nastran, Femap is also able to support other versions of Nastran including MSC/MD Nastran and NEiNastran. All of these solvers can be easily encapsulated within Femap while providing a high degree of solution control to the user.
Detailed and complete NX Nastran controls
Within Femap it is possible to directly define & control most aspects of the NX Nastran simulation. From controlling the solution options (such as defining an iterative solution), param keyword settings, specific job controls (such as restart controls, executive controls & manual controls with DMAP), case controls (load and constraint definition), model checking (geomcheck controls, weight & ground checks), and detailed result generation requests.
