GB/T 31054-2014Computer aided engineering for mechanical products—Finite element numerical calculation—Terminology (English PDF)

2.1 Basic Concepts

2.1.1 Computer Aided Engineering computeraidedengineering (CAE)

Use of computer technology and numerical analysis techniques (such as finite element method, finite difference method or discrete element method, etc.) to obtain the stress of a physical system

Field, temperature field or electromagnetic field and other physical processes and methods in response to the amount, commonly used in the evaluation system functionality and performance, optimize the structure, process or cost

And other purposes.

2.1.2 Finite element method finiteelementmethod (FEM)

Finite Element Method

Continuous solving domain finite discrete units, and given constraints conditions, using the finite element approximation of real approximate solution of Physics

Numerical analysis of the system.

2.1.3 Finite Element Analysis finiteelementanalysis (FEA)

Structural performance analysis based on the finite element method.

2.1.4 Unit element

Geometric, physical properties of the smallest solving domain.

2.1.5 Node

The hinge point between the units.

Note. Each unit contact occurs only at the nodes and the adjacent unit and the outside.

2.1.6 Pretreatment preprocessing

Geometry processing, finite element division, physical parameter setting and boundary conditions imposed by the process.

2.1.7 Solving solve

Setting Solving Environments (or conditions) and the process of seeking approximate solutions.

2.1.8 Post-processing

Solving the results of the other tests during the processing, analysis and assessment.
