Elements fall into four major categories: 2D line elements, 2D planar elements, and 3D solid elements which are all used to define geometry; and special elements used to apply boundary conditions. For example special elements might include gap elements to specify a gap between two pieces of geometry.
What does MSC Nastran stand for?
NASTRAN is a finite element analysis (FEA) program that was originally developed for NASA in the late 1960s under United States government funding for the aerospace industry. The MacNeal-Schwendler Corporation (MSC) was one of the principal and original developers of the publicly available NASTRAN code.

What is the basic structure of finite element method?
The structure of finite element methods A finite element method is characterized by a variational formulation, a discretization strategy, one or more solution algorithms, and post-processing procedures.
What is the basic of finite element method?
FEA Basics How Does FEA Work? The finite element method is a mathematical procedure used to calculate approximate solutions to differential equations. The goal of this procedure is to transform the differential equations into a set of linear equations, which can then be solved by the computer in a routine manner.
Why is finite element method called finite?
The finite element method (FEM) is a widely used method for numerically solving differential equations arising in engineering and mathematical modeling. To solve a problem, the FEM subdivides a large system into smaller, simpler parts that are called finite elements.
