Femap是一款独立于cad的前、后处理器，来自西门子PLM软件，用于通过有限元(FEA)方法进行工程分析(有限元分析- FEA)。这意味着Femap是用户和求解器之间的纽带——在工程分析问题中执行计算的核心。Femap集成了NX Nastran求解器，运行在Microsoft Windows上，是Velocity系列产品的一部分，是一个独立的、功能全面的环境，用于建模、模拟和评估产品性能分析结果。
Femap is a CAD-independent pre- and post-processor from Siemens PLM Software for carrying out engineering analysis by the method of finite elements (FEA) (Finite Element Analysis – FEA). This means that Femap is the link between the user and the solver – the core that performs computations in engineering analysis problems. Femap, integrated with the NX Nastran solver, runs on Microsoft Windows and is part of the Velocity Series product line and is an independent, full-featured environment for modeling, simulating and evaluating product performance analysis results.
The Femap system based on the NX Nastran solver allows you to: analyze the dynamics and strength of structures, machines and structures, obtain solutions for non-stationary nonlinear spatial problems, problems in the mechanics of composites and composite structures, structural and technological mechanics, analyze heat transfer, obtain solutions for problems in fluid and gas mechanics related multidisciplinary tasks.
Basic Femap modules with NX Nastran allow you to perform basic types of engineering analysis, such as linear static analysis, analysis of frequencies and modes of free vibration, buckling analysis of structures, analysis of problems of stationary and non-stationary heat transfer, basic capabilities of nonlinear analysis. Basic nonlinear analysis includes taking into account such nonlinearities as geometric (large deformations, displacements, tracking loads) and physical (taking into account nonlinear materials – plasticity, creep, viscoelasticity), taking into account contact interaction at small displacements – “linear” contact, taking into account contact with the continuity condition … The Advanced Nonlinear module is used in the analysis of large nonlinearities (including deformation of[Elastomer | elastomers], taking into account the spatial contact interaction), a combination of various types of nonlinearities, as well as in modeling and calculating fast nonlinear dynamic processes based on an explicit integration scheme. Femap includes three additional modules: Femap Flow Solver – allows you to analyze hydro and gas dynamics; Femap Advanced Thermal Solver – provides a set of capabilities for the analysis of heat and mass transfer, including modeling of fluid channels, associated convection and analysis of hydro-, gas-dynamic flows; Femap Thermal Solver is a solution for temperature analysis and heat transfer analysis. Femap is used by design professionals to model complex structures, systems and processes such as satellites, aircraft, military electronic equipment, heavy construction equipment, cranes, marine transport and process equipment.
