『叁』 用matlab进行磁场的有限元分析

1:我明白楼主的意思，你需要进行迭代优化之类的操作吧，如果你要用matlab进行有限元分回析，那么就答我用过的fem的工具箱来说，是无法满足复杂结构甚至一些带有自由曲面的结构的分析的。并且它也没有电磁场分析模块。
如果你还是想用matlab来做，那么就需要认真学习有限元的基础知识，先对磁场建立数学模型，然后采用算法划分网格，完成刚度矩阵的装配，从而得到最终分析结果。这是唯一的路。

2：其实有别的方法达到楼主的要求，就是 采用ansys 的 apdl 语言编程。是可以满足你的要求的。

上面的方法取决于你的研究深度，以及时间是否允许。供您参考！

『肆』 有限元求解2维和3维亥姆霍兹方程，是用fortran matlab等编程语言，还是 Ansys、Ansoft、FLUX等专业软件

ansys、flux之类的功能比较正规点， 设置一下就可以做分析， 但是你有什么回新奇点的想法答大概是很难实现的了
matlab有个FEM函数包， 也许做这方面能容易些吧。

如果你是公司里要做事情， 用ansys flux这种现成的就好了。 如果是搞研究要琢磨算法或者写论文的话也许matlab好一些。 如果研究完了要实用的话， 可以等matlab做通了转fortran， 速度能快一些

写代码比较省心， 要是能设置好分布式计算的话， 算几天什么数据都有了 。 而且用ansys的话论文里对算法、精度、开销、细节之类的也不太好分析吧
我是说ansys， flux之类的东西方法都是固定的， 不是用来研究的， 如果就具体某类问题你选了一个比较适合的方法，做了一些适当的改进的话， 自己写个程序就要比用这些更实用点。
是的

『伍』 FEMLAB软件的简介

COMSOL的起源：COMSOL最先是Matlab的一个工具箱（Toolbox），叫做Toolbox 1.0。后来改名为Femlab 1.0（FEM为有限元，LAB是取用的Matlab），这个名字也一直沿用到Femlab 3.1。

从3.2a的版本开始，正式命名为COMSOL Multiphysics，因为COMSOL公司除了Femlab外又推出了COMSOL Script和COMSOL Reaction Engineering等一系列相关软件。这两款软件也相当于Femlab的工具箱，也是为了满足科研人员更高的要求。如在COMSOL Script中，你可以自己编程得到自己想要的模型并求解；你也可以通过编程在COMSOL基础上开发新的适用本专业的软件，也就是一个二次开发工具。所以COMSOL只是个公司名，软件名应该是COMSOL Multiphysics，但由于现在大家都习惯了，也就不再计较这些了。

Multiphysics翻译为多物理场，因此这个软件的优势就在于多物理场耦合方面。多物理场的本质就是偏微分方程组（PDEs），所以只要是可以用偏微分方程组描述的物理现像，COMSOL都能够很好的计算、模拟、仿真。

发展至今，COMSOL现在有一个基本模块和八个专业模块：结构力学模块 (Structural Mechanics Mole)、化学工程模块 ( Chemical Engineering Mole)、热传递模块 ( Heat Transfer Mole)、地球科学模块（Earth Science Mole）、射频模块（RF Mole）、AC/DC模块( AC/DC Mole)、微机电模块 ( MEMS Mole)、声学模块 (Acoustics Mole)。以及反应工程实验室( COMSOL Reaction Engineering LAB)、信号与系统实验室（Signal&System LAB）、最优化实验室(Optimization LAB)、CAD导入模块( CAD Import Mole)、二次开发模块( COMSOL ScriptTM)。

COMSOL软件中国总代理商中仿科技也是一家实力非常强的公司。中仿科技主要负责COMSOL软件在中国地区（包括香港和澳门）的销售、市场活动、技术支持及培训。中仿科技和国内外众多企业、科研单位、高校有着长期紧密合作关系。为客户提供专业的工程解决方案和高质量的专业工程应用服务。
