This document provides recommendations for establishing a specification document for a finite element analysis (FEA) for a mechanical product, including type, procedure, modelling principle, solution, analysis and evaluation of the solution results, solution results interpretation, solution results report, and documentary management. It is applicable for FEA based structural analysis for mechanical products. This document can be used in the development of other standards and in support of communications among diverse, interested parties/stakeholders. This document is applicable to all types of organizations (e.g., commercial enterprises, government agencies, not-for-profit organizations). Model-based technology has been used throughout the product life cycle, from its design to the simulation, process, production, maintenance, and disposal, whereby generates a lot of model-based (3D) technical product documents. Simulation is an indispensable part of the product life cycle. The standardization of the technical product documents generated during the operation of simulation is one of the major concerns of ISO/TC 10/SC6. Most of the work of mechanical product design simulation is mechanics analysis, which benefits the R&D of mechanical products with higher quality, lower budget, and shorter time period. Among others, Finite element analysis (FEA) is the most frequently used simulation-based mechanics analysis methods in mechanical product design. FEA for mechanics analysis in product design has been applied in various industry sectors for a long time, therefor gradually evolved into a mature technology. The FEA models and the reports of results are intrinsically technical product documentation, and could be viewed as a kind of functional digital mock-up for mechanical products of great significance in performance evaluation and analysis. The standardization of the models and reports derived from FEA of mechanics analysis should be conducted in ISO/TC 10/SC 6 with high priority. For the simulation-based mechanics analysis for mechanical products using finite element analysis, this proposal specifies the requirements for FEA models and results, including specifications for geometric models, meshing, loading, boundary and initial conditions, solver, visualization, etc. The requirements are categorized as follows: 1) General requirements: including definitions and terminology of finite element analysis, the basic workflow of finite element analysis, models, data, and relevant information involved in finite element analysis; 2) Requirements for modelling of finite element analysis: including geometric modelling and model processing, determination and expression of material properties, selection and verification of the element type, determination of grid cell length and the density of grid, definition and application of the load, selection and application of boundary and initial conditions, model inspection, etc. 3) Requirements for solving and analysis of finite element models: including selection of a solver, analysis type selection, setting parameters of analysis, etc. 4) Post-processing requirements of finite element analysis, including visualization and analysis, contents of the finite element report, inspection, and verification of finite element analysis results, etc.
