有限元分析 Finite element method

（重定向自Finite element analysis）

有限元分析，即有限元方法（冯康首次发现时称为基于变分原理的差分方法），是一种用于求解微分方程组或积分方程组数值解的数值技术。这一解法基于完全消除微分方程，即将微分方程转化为代数方程组（稳定情形）；或将偏微分方程（组）改写为常微分方程（组）的逼近，这样可以用标准的数值技术（例如欧拉法，龙格－库塔法等）求解。

在解偏微分方程的过程中，主要的难点是如何构造一个方程来逼近原本研究的方程，并且该过程还需要保持数值稳定性。目前有许多处理的方法，他们各有利弊。当区域改变时（就像一个边界可变的固体），当需要的精确度在整个区域上变化，或者当解缺少光滑性时，有限元方法是在复杂区域（像汽车和输油管道）上解偏微分方程的一个很好的选择。例如，在正面碰撞仿真时，有可能在"重要"区域（例如汽车的前部）增加预先设定的精确度并在车辆的末尾减少精度（如此可以减少仿真所需消耗）;另一个例子是模拟地球的气候模式，预先设定陆地部分的精确度高于广阔海洋部分的精确度是非常重要的。

Finite element method 有限元分析

（重定向自Finite element analysis）
FEM mesh created by an analyst prior to finding a solution to a magnetic problem using FEM software. Colours indicate that the analyst has set material properties for each zone, in this case a conducting wire coil in orange; a ferromagnetic component (perhaps iron) in light blue; and air in grey. Although the geometry may seem simple, it would be very challenging to calculate the magnetic field for this setup without FEM software, using equations alone.FEM solution to the problem at left, involving a cylindrically shaped magnetic shield. The ferromagnetic cylindrical part is shielding the area inside the cylinder by diverting the magnetic field created by the coil (rectangular area on the right). The color represents the amplitude of the magnetic flux density, as indicated by the scale in the inset legend, red being high amplitude. The area inside the cylinder is low amplitude (dark blue, with widely spaced lines of magnetic flux), which suggests that the shield is performing as it was designed to.

The finite element method (FEM) is a numerical technique for finding approximate solutions to boundary value problems for partial differential equations. It is also referred to as finite element analysis (FEA). FEM subdivides a large problem into smaller, simpler, parts, called finite elements. The simple equations that model these finite elements are then assembled into a larger system of equations that models the entire problem. FEM then uses variational methods from the calculus of variations to approximate a solution by minimizing an associated error function.
