   源码介绍

本书针对ANSYS公司的有限元分析平台Workbench ,详细介绍了软件的功能及应用。本书内容丰富且涉及领域较广，使读者在掌握软件操作的同时，也能掌握解决相关工程领域实际问题的思路与方法，并能自如地解决本领域所出现的问题。
全书分为6篇，共26章，第1篇从有限元分析着手，讲解工程问题的数学物理方程及Workbench平台的基础应用知识；第2篇以基础范例为指导，讲解在Workbench平台中进行结构静力学分析、模态分析、谐响应分析、响应谱分析、随机振动分析及瞬态动力学分析；第3篇作为进阶部分，讲解接触分析、显式动力学分析、复合材料分析、疲劳分析及压电分析；第4篇以项目范例为指导，讲解稳态热力学分析、瞬态热力学分析、计算流体动力学分析、电场分析及磁场分析。本书配套资源中的第5篇作为高级应用篇，讲解结构优化分析、线性屈曲分析、APDL编程及声学分析等；第6篇主要讲解多物理场耦合分析，包括电磁耦合、流固耦合、振动噪声等。
