AIFEM is intelligent software that is independently developed by Nanjing Tianfu Software Co., Ltd for full-process finite element analysis (FEA). During software requirement analysis, AIFEM developers integrate industrial intelligence, digital twins, and data driving technologies to implement digital product models based on numerical simulation calculation, parameter sensitivity analysis, and numerical experiment databases. AIFEM facilitates engineering application in the following aspects: The model repair and automatic meshing features of AIFEM minimize the pre-processing workload of engineers, and the support for abundant element types and material constitutive equations facilitates computing and analysis in the solid mechanics, structural mechanics, heat transfer, and electromagnetics fields. Moreover, AIFEM can compute flutter, gust response, and static aeroelasticity during multiphysics coupling analysis. AIFEM helps industrial enterprises establish an integrated design, simulation, and optimization process and improve product R&D efficiency. CHARACTERISTICS (1) AIFEM provides both universal features that apply to multiple fields and custom features that are tailored to specialized branches. AIFEM reduces technical requirements and offers simplified and efficient simulation analysis and design optimization tools to run actual projects. (2) AIFEM collects and generalizes practical and instructive analytical solutions, a large amount of public trial data, and widely recognized reliable numerical analysis data. AIFEM also fully validates the solver. These measures ensure that users have a quantitative and thorough understanding and control of data accuracy and reliability. (3) AIFEM developers conduct in-depth surveys on the requirements and habits of engineers to optimize the usage process, database storage, and data statistics and analysis and reduce repetitive work as much as possible.
