What is Femap?

As an engineer, you should 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. Femap is recognized as the world’s leading CAD-independent Windows-native pre- and post- processor for advanced engineering finite element analysis.

Why Femap?

As a standalone simulation solution, Femap incorporates finite element modeling and analysis functionality within a modern user-interface. Supporting a full range of advanced analysis types, Femap can help you analyze parts and assemblies, model composite materials, and review simulation results quickly and efficiently. You can even customize Femap to suit your design processes. We’ve included some of the reasons why you should consider Femap as the first choice for your engineering analysis environment below, and what some of our customers say about Femap.

What is Femap?

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 components, assemblies or systems and determine the behavioral response for a given operating environment.

Using Femap’s digital simulation capabilities you can:

  • Predict and improve product performance and reliability
  • Reduce time-consuming and costly physical prototyping and testing
  • Evaluate different designs and materials
  • Optimize your designs and reduce material usage


Femap is CAD-independent and can access geometry data from all major CAD systems including CATIA, Pro/Engineer, NX, Solid Edge, SolidWorks 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.

Finite Element Modeling

The full finite element model with underlying data is fully exposed by Femap, allowing you to view, create or modify entities directly. Femap’s grouping, layering and visualization tools help you to manage model display while creating and setting up the finite element model.

Femap includes specialized capabilities to help with modeling tasks including:

  • Mid-plane extraction of thin-walled structures to aid creation of more efficient and accurate shell models
  • Weldment modeling that connects discrete solid welded parts together into a contiguous model
  • Data surfaces that allow you to create complex loading conditions based on prior analysis output for multi-physics applications


  • CAD independent

  • System simulation

  • Statics, modal, buckling, dynamics, heat transfer, non-linear, etc.

  • Solver independent, NX Nastran

  • Multi-discipline engineer, analyst

Femap Usability

Femap packs in-depth finite element analysis functionality into an up-to-date user-interface and presents advanced modeling techniques in an intuitive style. You’ll find Femap quick to learn and you’ll be up and running after only two day’s training. If you are an infrequent user of simulation, you’ll be able to rapidly pick Femap up as and when you need to. Femap lets you get on with the task in hand efficiently, makes the best use of your time and boosts your productivity.


“In our work with SpaceShipOne, we selected Femap as the central processor before going to Nastran. In our opinion, it’s one of the best solutions on the market, and it’s very easy to use. We have other pre- and post-processors available, but they’re less user-friendly and less capable overall. Femap is a superior product.”

Femap with NX Nastran

Femap provides comprehensive functionality in an independent environment for modeling, simulation and review of product performance results.

Integration with NX Nastran

Femap has a 15 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.

VisQ solution job management

VisQ actively manages NX Nastran solutions from Femap, and provides users with advanced tools to define, schedule and track simulations.

Femap Thermal Solver

The Femap Thermal Solver adds state-of-the-art thermal analysis solutions to the Femap environment and provides fast and accurate solutions to complex thermal engineering problems. Using finite-element mesh, finite-volume based numerical techniques, the Femap Thermal Solver makes it easy to model nonlinear and transient heat transfer processes including conduction, radiation as well as phase change. Leading-edge solver technology provides solid reliability and superior solution speed for even the most challenging problems. With Femap, accurate thermal analysis can be performed quickly and effectively, delivering the engineering insight and turnaround speed needed to ensure success within today’s rapid development cycles.

Femap Advanced Nonlinear Solver

The NX Nastran Advanced Nonlinear software solution enables you to analyze models with nonlinearity from contacting parts, material nonlinearities and/or geometric nonlinearities (that is, large deformations).An add-on module of NX Nastran – Basic, the Advanced Nonlinear solver is an integration of the well-known and highly regarded ADINA solver into NX Nastran as Solution 601 for implicit solutions or Solution 701 for explicit solutions. The integration of the ADINA solver into Solution 601/701 is transparent to the user because the input and output formats are based on NX Nastran formats. Thus, to the user, the experience and usage of Solution 601/701 is completely Nastran-centric.

Femap Flow Solver

The Femap Flow Solver adds state-of-the-art computational fluid dynamics (CFD) analysis solutions to the Femap environment and provides fast, efficient and accurate solutions to complex CFD problems. A sophisticated algebraic multi-grid solver provides the backbone to a complete CFD capability that is able to support the simulation of both laminar and turbulent fluid flow, low speed and high speed compressible flow, forced flow, natural convection and mixed flows, all with multiple inlets, outlets and internal flow boundary conditions. This memory efficient capability ensures that solutions are solved quickly and easily. Additional flexibility is ensured by the support of both unstructured and structured meshing. The Femap Flow Solver provides an excellent complement to the Femap Thermal Solvers by providing the ability to couple the Femap Flow Solver together with the Femap Thermal Solver.
