我们为什么用workbench？

fwdandy

我现在用的是就是ansys11+proe4.0，先安装proe4，然后安装ansys11时，就会有提示是否关联这两套软件，简单设置以后，在proe4里面的模型可以相当方便的直接转到workbench或ansys里面。

我也感到迷惑，传统ansys已经做的很好了，分析功能也强大了，为什么现在又有这么多人开始研究和学习ansyswb呢？

我来总结一下优点吧！

１．workbench可以实现双向互导
２．自动探测接触
３．有分析向导
４．可以方便实现流固耦合
５．由于吸收了ＡＩ＊Ｅ网格处理的技术，自动六面体网格划分功能强大
６．还可以实现其他模块的集成（比如rigid dynamic）
６．操作十分方便

Top 10 Reasons to Use Workbench

While preparing for a recent user group meeting in California, someone who was attending asked if we could present some good reasons for him to use Workbench more. After some thought and discussion, we came up with the follow list of reasons why anlyst uses Workbench, and why we recommend it to our users.

10: Shorter and Shallower Learning Curve
People just seem to learn Workbench faster and are more productive sooner. This is especially true for younger engineers who are new to FE analysis and have a strong background with modern parametric CAD packages such as SolidWorks or Solid Edge.

9: Significant Say in Growth
Workbench is developing and growing every day. For many in the user community, this is the first time that they can participate in guiding the development of a code that, in our opinion, will soon dominate the CAE market. This is everyone’s opportunity to speak up and make an impact.

8: Automatic Report Creation
The process of creating reports for an analysis can sometimes take longer than the analysis. On occaision, schedules are so tight that no report is created at all, or only the results are captured. Both of these issues are addressed with the powerful automatic report generation feature in WB. Using this tool, companies can set up standardized reports, force the capture and retention of key pieces of information, and drastically reduce the amount of time required to make a report.

7: Built-in Process Standardization
When you start up WB, you may have noticed some stuff over on the right side of the screen. This is where wizards live. The product ships with some basic step-by-step guides. Many users see these as tools for helping low-end users do analysis, which they are in fact good for. But you can also create your own very sophisticated wizards that can lock down standard processes and ensure that key steps are carried out.

6: New Stuff is Going into WB
The cold, hard reality is that many of the new pre- and post-processing features that ANSYS, Inc. is creating to meet user requests are going into WB.

Virtual topology
Advanced solid modeling
“Engineering” loads
GAP meshing for field problems
New meshing technology

5: Less “Reinventing the Wheel”
Over the years, ANSYS users have gotten very good at writing macros to automate processes and do some pretty fancy things. Most of us enjoy this and it is a large part of our job satisfaction. But if you look at it honestly, hundreds of users around the world are “reinventing the wheel,” doing the same thing over and over again. With WB many of these common tasks are being built into the code from the ground up. It also includes tools like the Engineering Data tab that allow you to save things like material properties and time-dependent loads and share them with other users through a library.

4: Not a Technology that You Get Stuck In
One of the greatest fears that keeps users from trying Workbench is a concern that if they start a job in WB, they will have to stay in WB until they are done. Thanks to some open-minded planning by ANSYS, Inc. developers, you can jump out of WB at any point after you have meshed and finish up your job in ANSYS. The only downside is that geometry does not go with you, but we have not found that to be a serious drawback. For example, one can specify a group of surfaces as a named component in WB, and thus all associated nodes of the underlying WB mesh are grouped into a component on the ANSYS import for easy reference.

3: Setting Stuff Up Is Faster
Analyst's experience is that it’s just a lot faster to set stuff up in Workbench. There are a lot of reasons for this, but some of the key ones that we have seen are:

Consolidation: many tasks have been combined into one
CAD associativity and parametrics
Object paradigm (you click on something in the tree then operate on it)
Context sensitive menus and icons reduce clutter and “hunting” for commands
Simplified processes
Automatic Contact Detection

2: Robust Meshing
Far and away the most common reason for analyst to use Workbench is to mesh poor geometry. Our single largest productivity hit in doing analyses was dealing with geometry that had gaps or slivers in it. Workbench is much better with this sort of thing, and the robust mesher has grown to have many of the controls that users have asked for, and even more can be added.

1: CAD Associativity
Just edging out “Robust Meshing” is that Workbench models can be associative to CAD models. This can be a huge savings and is really the one thing that Workbench does so much better than any other solution out there. It not only delivers huge savings in time and effort, but also allows you to easily do studies that you would never have considered before.

workbench的疲劳计算功能可能要强一些

sw2004

workbench类似于cosmosworks,很容易上手,应该是ANSYS以后发展的方向,
就是计算后文件太大了,计算一个案例差不多占用空间1G多

本科毕业论文用的ansys classic做摩托车车架分析，由于只做分析部分已经实验部分，建模部分我没有做，是一个研究生师兄做的，所以对ansys classic建模用的不多，但在开始学习的时候也用过它来做过一些简单模型例子，感觉就是非常别扭。相对与PROE,CATIA这些3D软件效率慢多了。
       现在研究生的毕业论文也要开始搞了，也要做分析，所以还是选用ansys，但由于这次要我自己建模了，我是在CATIA中建立的风叶叶片模型，尝试保存为iges格式再导入ansys classic中做分析，可是数据丢失严重，因为风叶叶片的建模使用了比较高级的曲面建模，所以导入ANSYS中丢失很多数据，导致不能使用。
      正是在这个困惑的时期，我才发现WB这个适合我用的东西，所以现在开始慢慢的摸索WB的用法，总的来说，WB容易上手，如果有ANSYS CLASSIC基础的朋友更加是觉得非常简单。
      但我想在这里顺便问一个问题，因为我用的是WB11，而我手头上的教程的WB10，我发现在WB10中的frequency finder和shape finder在WB11中找不到，非常郁闷，希望知道的人给我解答一下！谢谢

我已经回答了楼上的问题了呀
学WB也有一段时间了，说下自己的感受。因为学过一点ANSYS CLASSIC，感觉如果要学好WB，有一定的ANSYS CLASSIC基础还是比较有帮助的。特别是对于WB的理解方面。但是要学好WB也不象想象中的那样简单，而且目前资料也少的可怜，专门的中文书本更是没有。只能看英文的学习，对于英语基础不好的人来说的确比较吃力。看了信息资源版的一个CAE工程师待遇帖，如果真的如此惨淡的话还有几个人愿意来学有限元。
在SIMWE也混了几个月的时间了，其他版块我不知道，对这个版还是比较熟悉的，因为每天有相当部分的时间都在这里。但我却发现了一个现象，就是绝大部分的会员到这里来都是问问题的（意思就是索取），来跟大家交流或者能上传资料，为版块做贡献的少之又少。其实如果你手头有学习的资料或者实例，方便的话都可以传上来，论坛作为共同学习交流的平台，绝对是最理想的方式之一。
讲多了，但只是一个小小的建议。

我是在学习Inventor11时接触Ansys11，算是半路出家哈哈，但Classic的基础界面，差点把我看晕了，后来无意间发现了workbanch，因为用以前Inventor的界面就是WB的界面，很快就上手了，哎，如果早点找到就爽了，使用了一段时间，觉得它的产品零件分析能力果然强，虽然我是搞造型设计，更多的是搞概念设计，但有了它，结构上的优缺点一下子就很明确了，和工程师间的沟通好了很多。

以往使用ansys做過結構分析，
設定上花了好多的時間，
workbench則是方便許多，
第一次使用時，
依照wizard的順序，
一下子就把該設定的設好了，
上手性真的超快的！
不過，
DS求解後的檔案超大的，
害我的硬盤一下子就快爆掉。

应该跟同一模型在Classic得到的结果文件一样大。

这年头，在成为神枪手之前得先成为快枪手，所以WB还是比较好的东西……

在inventor2008里边建立的3D模型，保存为IGES格式，导入ansys11.0中一直出错，导入不过在workbench中就没有问题。也不知道是什么原因？

高端专业复杂的有限元系统，有用。可是，低端简单易用的有限元系统，也有它的用处。
做产品设计的工程师，不能事事都求作分析的专业人士。特别是在概念设计的时候。
过去用的是公式，计算器，加铅笔，不是把毫不相关的结构当成“梁”来计算的吗？
后来，有了EXCEL，简单一点了，还是“毛估估”的计算，最后要通过实验室的实验数据鉴定。
和这些传统工具相比，AWB就使设计工程师有了前所未有的方便工具。不错，误差是不小，解决方法有两条：
一，求专业牛人。问题是，初级设计，要花多少钱才付得起牛人的计算？初级方案很多，有必要做精确计算吗？
二，做出样本，实验数据说话。问题是：钱和时间。

在这种条件下，设计工程师不出PROE，或者CATIA，直接就把AWB调用，算一下要算的东西，回头继续设计工作。到了设计基本完成，主要数据要求精算时，再求牛人，对于节省工程预算，提高设计质量，都有好处。

当然，对于一些商用软件公司，出于销售需要，搞些“文人相轻”，互相打压的市场行为，做工程师的，心里应该明白：这不是咱们要关心的。

workbench比较傻瓜，适合机械设计用，可以缩短研发时间，但是ANSYS功能强大，几乎包括所有工程力学领域，适合研究，比较结构工程，桥梁工程分析workbench是无能为力的！

小弟也是最近才開始接觸workbench
用了一段時間真的覺得“很方便”
因為有時工作需要，使用pro-e繪圖完畢，要轉入分析軟體時
利用workbench作轉入，一次ok，不用再多花時間在轉檔上面
這點對於每次要改模型檔案的我，實在是方便許多，也省了滿多時間

刚开始我没感觉到WORKBRNCH的好处，当我开始用的时候，感觉特方便,总结如下：
1 建模功能特别强大，和几种三维软件（UG  PRO-E  SOLIDworks）的功能不相上下。
2 与这些软件（UG  PRO-E  SOLIDworks）的接口非常好，修改模型也特别方便。
3 划分网格非常方便，尤其是六面体，很容易划分的非常好。
4 接触设置很方便，比经典ANSYS容易多了，这点我深有感触。

the ansys corp. has many produts such as designmodels( maybe some spelling error) for modeling and ICEM(maybe spelling error) for mesh etc. the ansys workbench is going to input all products of ansys into one system for convenience use.
