ansys结构分析入门-命令流

1 ANSYS概述1.1 ANSYS简介ANSYS是一种广泛的商业套装工程分析软件。

所谓工程分析软件，主要是在机械结构系统受到外力负载所出现的反应，例如应力、位移、温度等，根据该反应可知道机械结构系统受到外力负载后的状态，进而判断是否符合设计要求。

一般机械结构系统的几何结构相当复杂，受的负载也相当多，理论分析往往无法进行。

想要解答，必须先简化结构，采用数值模拟方法分析。

由于计算机行业的发展，相应的软件也应运而生，ANSYS软件在工程上应用相当广泛，在机械、电机、土木、电子及航空等领域的使用，都能达到某种程度的可信度，颇获各界好评。

使用该软件，能够降低设计成本，缩短设计时间。

到80年代初期，国际上较大型的面向工程的有限元通用软件主要有：ANSYS, NASTRAN, ASKA, ADINA, SAP等。

以ANSYS为代表的工程数值模拟软件，是一个多用途的有限元法分析软件，它从1971年的2.0版本与今天的5.7版本已有很大的不同，起初它仅提供结构线性分析和热分析，现在可用来求结构、流体、电力、电磁场及碰撞等问题的解答。

它包含了前置处理、解题程序以及后置处理，将有限元分析、计算机图形学和优化技术相结合，已成为现代工程学问题必不可少的有力工具。

1.2ANSYS软件主要功能ANSYS软件是融结构、热、流体、电磁、声学于一体的大型通用有限元软件，可广泛的用于核工业、铁道、石油化工、航空航天、机械制造、能源、汽车交通、国防军工、电子、土木工程、生物医学、水利、日用家电等一般工业及科学研究。

该软件提供了不断改进的功能清单，具体包括：结构高度非线性分析、电磁分析、计算流体力学分析、设计优化、接触分析、自适应网格划分及利用ANSYS参数设计语言扩展宏命令功能。

1.3ANSYS软件主要特点主要技术特点：∙唯一能实现多场及多场耦合分析的软件∙唯一实现前后处理、求解及多场分析统一数据库的一体化大型FEA软件∙唯一具有多物理场优化功能的FEA软件∙唯一具有中文界面的大型通用有限元软件∙强大的非线性分析功能∙多种求解器分别适用于不同的问题及不同的硬件配置∙支持异种、异构平台的网络浮动，在异种、异构平台上用户界面统一、数据文件全部兼容∙强大的并行计算功能支持分布式并行及共享内存式并行∙多种自动网格划分技术∙良好的用户开发环境支持的图形传递标准：∙SAT∙Parasolid∙STEP与CAD软件的接口∙Unigraphics∙Pro/ENGINEER∙I-Deas∙Catia∙CADDS∙SolidEdge∙SolidWorks1.4 运行环境（ANSYS5.7）Computer: Pentium-class systemMemory (RAM): 64 MB以上Hard Disk: 500MB以上自由空间.Operating System: Microsoft Windows 2000, Windows NT 4.0 (SP 5 or higher) or Windows 98 Graphics: A Windows 2000/NT 4.0 or 98 supported Graphics Card, capable of 1024x768 in High Color (16-bit).A 17 inch monitor (or larger) compatible with the above mentioned card is recommended.2ANSYS 的基本使用2.1 ANSYS环境简介ANSYS有两种模式：一种是交互模式（Interactive Mode），另一个是非交互模式（Batch Mode）。
