Femap

Windows-based pre- and post-processor for FEA

The Challenge: Performance driven design

Femap is the worlds leading Windows-based engineering simulation tool forfinite element analysis (FEA).

Engineers worldwide use Femap to model and simulate everything from simplesolid components to entire spacecraft assemblies throughout a broad range ofengineering disciplines. From simple linear static analysis right through toadvanced solutions based computational fluid dynamics engineers and analystsuse Femap to virtually simulate a complete range of product behavior to reducecostly prototypes and physical testing and before committing to e!pensiveproduct development plans. "his ensures higher product #uality lowerdevelopment costs decreased testing overheads and reduced productdevelopment time.

Femap is based on an advanced set of open technologies that enable it to worsimply and easily within customer engineering simulation environments. Femapis primarily based on *arasolid which ensures direct access to some +, of theworlds digital product definition data. n addition a number of state-of-the-art

geometric e!tensions ensure that Femap is able to wor with geometry fromvirtually any source directly and seamlessly. Femap also wors with anunusually broad range of finite element solver solutions. "his maes Femap avery logical and fle!ible solution that is simply tailored for even the mostdemanding customer needs.

Femaps open technologies are also Windows based maing them readilyaccessible. "his not only provides a high degree of familiarity for the ma/ority ofusers but it also ensures that Femap brings powerful digital simulation directly tothe engineers destop easily and affordably.

Femap with 01 0astran combines two of the worlds most popular and powerfulstructural analysis programs for simulating product performance characteristicsof structures and mechanical components. As such Femap with 01 0astranprovides a very cost effective Windows-native 2AE solution that combinesFemaps widely used pre- and post-processing capabilities with the well nownand respected analysis capabilities of 01 0astran.

3ased upon its 4,-year history of woring closely with 0astran solvers Femapwith 01 0astran seamlessly integrates 01 0astran into the Femap environmentand directly supports a broad range of 01 0astran capabilities such as linearand non-linear static normal modes Eigenvalue transient5dynamic

fre#uency5harmonic response response spectrum random response andbucling. "here are also additional 01 0astran options available for aero-elasticity super-elements optimi6ation and 7A*. Femap with 01 0astran alsoprovides a comprehensive range of detailed functionality to directly define andcontrol most aspects of modeling simulation with 01 0astran and subse#uentpost processing operations.

A maret-leading component of %&$ and 8elocity $eries9 Femap also providesan independent bacbone to a number of other well nown and industryrespected simulation products including $inda5& from 0etwor Analysis nc.:0Ei0astran 7odeler from 0oran Engineering nc.: and 7$2.0astran for

Windows from 7$2.$oftware. n particular Femap's capabilities 0Ei0astran forWindows and 0Ei0astran 7odeler are due to Femaps pre- and post-processinge!pertise together with the 0astran solver solution.
