What is Femap?
FEMAP® by Siemens PLM Software is a professional level pre- and postprocessor used for preparing models and viewing the results of engineering analyses for structural, thermal, or fluid problems. Femap can import geometry from all major CAD systems and can use a wide variety of solvers including finite element analysis (FEA) and computation fluid dynamics (CFD). Femap runs on Microsoft Windows.
Why Femap?
Femap is a premier digital prototyping tool because of its extensive capabilities, high level of performance, and long term industry proven reputation in the following key areas of finite element modeling and post processing:
1. CAD Neutral. Imports all major CAD files with wide functionality for geometry clean up and feature suppression.
Solid Edge
SolidWorks
CATIA

Autodesk
NX Unigraphics
I-deas
2. Solver Independent. Compatible with a full complement of highly regarded implicit and explicit FEA and CFD solvers including NEi, NX, and MSC Nastran, LS Dyna, Maya TMG-Flow and TMG Thermal, Abaqus, and ANSYS. Provides solutions to linear and nonlinear structural stress, deformation, modal analysis, thermal, heat transfer, impact, crash, fluid flow, multiphysics, aeroelasticity, optimization, and rotor dynamics engineering problems

3. High quality, sophisticated meshing capabilities. Full control over the meshing process for all geometry types with the ability to work around deficient geometry. Example 1: Surface meshing API utility allows interactive mesh editing for surface tri meshing prior to solid tet meshing. Example 2: semi automatic hex meshing tools subdivide solid into meshable regions.
4. Range of Modeling Functionality -- Beams, Shells, Solids, Assemblies, and Composites.
Beams can be created directly as FE entities or meshed from curve geometry. Section properties calculated and fully displayed to easily identify orientation and offsets. Shells maintain accuracy and keep model size down for thin plate type structures. Mid plane extraction on geometry and shell meshing provides greater accuracy with smaller models than one element through a solid. Simulate assemblies and the interaction between members with easy automatic assembly detection, linear or nonlinear contact with or without friction, or glued contact, spot weld elements, and full access to manual connection definition. Easy contact visualization with selective transparency. Full support for composite materials with easy entry, view, organization, and manipulation of plies.
5. Real World Fidelity through Accurate Choice of Loads and Boundary Conditions
Apply loads and boundary conditions to geometry and the FE mesh, data mapping onto the structure from other sources, loads represented as functions.
6. Broad Range of Analysis Types and Engineering Disciplines
In addition to handling basic analysis types like linear statics, modal, buckling, and steady state heat transfer, Femap can support many advanced type solutions and analysis capabilities in various solvers.
Full Advanced Dynamics Capabilities
Dynamic analysis is a very important part of product verification. Femap can perform transient response, frequency response, random analysis, response spectra generation and analysis, complex modes, Dynamic Design Analysis Method (DDAM). Plus includes full modeling functionality with mass and damping elements, loading functions, and post processing of results.
Advanced Nonlinear Capabilities.
Model large deflections, nonlinear material properties, contact, impact or crash with implicit and explicit types of analysis.
Advanced Thermal Capabilities
Conduction, convection, and radiation with steady state and transient heat transfer analysis. Thermal couplings and boundary conditions, convection correlation, temperature mapping and duct flow.
Fluid Flow Capabilities
Analyze fluid flow as well as fluid cooling effects in thermal analysis and fluid-structure interaction. Fans, vents, flow surfaces and high speed flow.
Rotor Dynamics Capabilities
Determine dynamic behavior of parts that rotate at high speeds.
7. Full Complement of Post Processing and Visualization Tools
Allows complete, in-depth exploration of results including free body diagrams, beam diagrams, data tables, graphs, contour plots, and animations.
8. Customization and automation of simulation tasks.
9. Ease of Use.
Windows native with a flexible analysis process. The user is not forced into a strict series of actions. Work through the menu, model information tree or both.
10. Best Price for Functionality.
Who Uses Femap?
Femap is for product design and development professionals who need to do more effective analysis and have moved beyond the capabilities found in typical in-CAD simulation software or more limited FEA products. They need a CAE tool that provides them with more functionality, more control over they analysis process, and provides more accurate results. They have moved from simple parts to assemblies and more complex systems. They have moved from being primarily involved in CAD design with occasional need for validation to more involvement with engineering and analysis. They have climbed the FEA learning curve and are ready for the next level of analysis.
Femap with NEi Nastran
Integrating tightly with
NEi Nastran, this combination provides significant additional functionality for Nastran users. This includes advanced capabilities for composites engineering and analysis with tools for advanced failure criteria for first ply failure like Puck and LARC02 and Progressive Ply Failure Analysis (PPFA™) for simulation of behavior beyond first ply failure. Automated Impact Analysis (AIA™) provides sophisticated simulation for drop tests and implicit impact studies. Productivity tools like Automated Surface Contact Generation (ASCG™) and Automated Edge Contact Generation (AECG™) help in industries with models having large shell like structures as found in ship building and automotive.
