CAD-neutral and solver-neutral, FEMAP has become the world’s most popular engineering analysis environment for Nastran users. It is widely used by the world’s leading engineering organizations and consultants to model complex products, systems and processes, including satellites, aircraft, defense, automotive vehicles, electronics, heavy construction equipment, lift cranes, marine vessels and process equipment. Siemens PLM Software’s FEMAP system facilitates an advanced engineering analysis environment.
CAD-neutral. Solver-neutral. Cost-effective.
The world’s most popular engineering analysis environment for Nastran users.
Includes FEMAP standalone pre- and post-processor for geometry import, creation and idealization, FE model meshing and setup and post analysis results viewing. CAD and solver independent and leverages Siemens PLM Software’s Parasolid modeling kernel that allows direct access to Parasolid data for surface and solid modeling in addition to advanced geometric tools necessary for accessing non-Parasolid geometry. From advanced beam modeling, mid-surface extraction and hex meshing to robust CAD import and idealization, FEMAP gives you unparalleled model control and flexibility with a broad range of loads, materials, analysis types with extensive visualization and postprocessing options.
FEMAP with NX Nastran - Base Module
The FEMAP with NX Nastran base module includes the core subset of NX Nastran solver functionality fully supported within FEMAP modeling environment and includes a robust suite of linear statics, normal modes, buckling, basic nonlinear, and heat transfer capabilities. This base module provides you access to a broad library of finite element types and material models, robust manipulation of load cases, along with several efficient solution sequences for linear statics analysis (including buckling) and normal modes analyses on models of unlimited size. The heat transfer capability provides solutions to steady state and transient thermal analysis and design problems. The basic nonlinear capabilities include nonlinear static and transient analyses that include large displacement and nonlinear material analysis as well as gap and slide line contact.
Other functionality also include in this base module includes linear surface to surface contact and glued connection that can be defined either between element faces or geometry surfaces and is easily set up with FEMAP’s assembly management functionality. Also supported in the base module is the CWELD spot weld and fastener element, the fast iterative solver efficient at solving large solid models, and the bolt preload capability.
FEMAP with NX Nastran - Dynamics
FEMAP with NX Nastran Dynamic response enables you to calculate your product's forced dynamic response to inputs (loads or motion) that vary with time or frequency, as well as compute complex eigenvalues. An add-on option to the FEMAP with NX Nastran base module, it complements the linear static capabilities found in the Basic solution.
The capabilities included in the Dynamics module include transient response – the dynamic response of a structure over a period of time, and frequency response, the response of a structure across a range of frequencies. In addition response spectra determination and application, random response and DDAM (Dynamic Design Analysis Method) - a method of shock spectrum analysis largely employed by the US Navy that can be used to determine the dynamic response of a component on board a ship or vessel subjected to shock loading caused by a sudden movement of the vessel due to a phenomenon such as an underwater explosion.
Dynamic response capabilities play a key role in various industries such as assessing passenger comfort in aircraft and automobiles under different operating conditions; determining whether engine frequencies or tire excitations from the road surface will adversely affect responses at other areas of a vehicle, such as at the steering column or in the seats; or, evaluating the effect of vibrations on the performance of consumer products and other high-tech electronic devices.
FEMAP with NX Nastran - Advanced Nonlinear
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.
