ANSYS之父John A. Swanson康奈尔大学访谈录
说是谈三个方面的东西，个人成长，ansys，然后搞能源，最后观众问了几个小问题。
院长问
院长说他妈很厉害，So I've read in several places the important role your mom blade in your upbringing, your commitment to excellence. I wonder if you could tell us a little bit above that, but that's sure they have.
Swanson说自己4岁没了爹，然后妈妈是学校老师，妈妈营造了一个环境，让他自己从小就觉得是第一名。有这种自我定位。然后就去了康奈尔。去康奈尔是因为有奖学金，Swanson后面给康奈尔和匹兹堡都捐了很多钱。去康奈尔是梦想，可是家里没钱，开始是算哪几个学校便宜，选了三个，结果有奖学金，就去了康奈尔。
I didn't have enough to buy food, so I had to work for a living. 在学校没钱，然后还要一边打工，结果挂了科。One of the worst shocks in my life was my first chemistry test. Yeah. Well, it was shocking was all of this to other students were saying it was it was rough. And I was you, I thought it was pretty easy. I failed. Not by much, I'm going to 59, but it was still failing. And then that caused me to reassess what I should be doing here. 考试挂科给了一个大的警醒。
其他同学都说化学很难考，而我却觉得很简单，结果挂科了，虽然差得不多59分， 但还是不及格。这让我重新考虑了我应该在这里做什么。
院长问： Who are the people who had the biggest impact on you? Well, I'll, I'll try on that. But it's not going to the answer.
Swanson说都靠自我驱动！！！打工了之后，最意外的是最简单的事情最重要。when they got into the industry, you know, what surprised me was how the simplest things were the most important.
学到的第二个点是：And so I learned that it's easier to take an exam if you understand the basic concepts and derive everything else. 解决问题的关键是找到关键的问题。no，是找到问题的本质，其他的都是基本观念的衍生。
第三个点事吹牛逼。自己过目不忘，确实不是凡人。Now so and a third skill I had was, I could remember lectures verbatim, just a couple notes in the margin, and then I could replay them. So I have to think that I'm not your normal student. I am who I am. Self-motivated.
等到毕业的时候对核跟航天有兴趣，就去了匹兹堡念博士，博士毕业就去了西屋电器。结果去了以后人家说搞核的人够了Well, we really got enough nuclear people，开始搞应力分析，搞编程，发现编程好玩。
I did two dimensional planar up programs for shells or programs for plates. I wrote programs for three-dimensional solids. And then I looked at it and I've done the same thing 56 times. Why don't I do it all at once? 这个还是打孔机时代，然后想要写软件。但是上面的人不推荐。
他自己的人格是工具型，完成任务型人格。somebody will tell me what what's important and I'll work on that.于是继续管一个应力分析的小团队。等到说米国政府不准备去火星了，很多人和工作都要撤掉，要换工作了，才开始考虑做ANSYS。
So I started a company. Now, people, okay, they say, Well, isn't that a risky thing to do? How could you do that? And I had job offers in my pocket and I had enough money to last a couple of months. And I could go out and do consulting at any number Westinghouse locations and others.
反正没也没什么压力，也没什么风险，要不给弄个公司开一开。结果公司还挺成功，院长问，公司挺好，干嘛在94年的时候把公司卖了，自己不当老板了？
Swanson说是不想搞管理，原来假装搞管理，周一做管理工作，其他时间写程序，可是公司的规模起来以后，这个模式走不通了，不行了，就把股权卖了，专心写程序了。
院长问了一个大问题。在ANSYS的那些年，技术上的成绩，哪些方面是最值得骄傲的？
Swanson说There were things I called I named power something.
Also, I did a, a user interface which was long before Windows or anything else. In fact, IBM put it up for a national award for design. And it was a little slow until I got a little book that explain how to do graphics without doing multiplication and division on just the inner. And it sparkled. If it was just phenomenal, that things that were taking slow, we're instantaneously things with flashing and so on.
这个答案实在是意外。ANSYS的难用好像是默认的，可是上个世纪，人家做出来的UI比微软还早！！！
第二个areas magic. 后处理上面出contour plot上面用彩色，别人想的是画“磁力线”一个样，给线条上色，Swanson是给磁力线之间的区域上色。解释：因为物理学是场，对一个场的描绘还是磁力线式的方式。
Don't color the lines. Go to the spaces between the lines. Yes. So things like that.
ANSYS在90年代就成了CAE界的leader，他是从easy to use上得来的。
问：为什么就永远的离开了ANSYS
答：I found I was paying more for the lawyer bills，economics says, it's probably not worth doing this.经济上不划算了。。。。做咨询工作更好玩。
问：来学校、交流这么久，你认为我们该怎么教学生But I mean, based on these interactions, are there gaps, are there things we should be thinking about? Does the college in terms of how we educate?
答：可以加两个课程： I'm emphasizes both courses。一个就是跟钱走。One basic rule is follow the money. Now, if you can't do the economics, nothing else follows.没钱就什么都是扯谈了。 So now, who benefits? 所以接下去的问题是可以为谁创造价值。举了个例子。意思不大。
第二个是systems。
No matter how theoretically you are or how intelligent you are if you can't get the money behind it or convince somebody that this is the future. It's going to stay at the university.
观众问
学生Sam问：how do you go from a technical degree and a lot of technical experience out of college and starting your own company and learning all the skills that are required to manage and start a business like that. 怎么从工科生就开公司，然后成功了。
答：Well, let me be clear that I didn't know where I was going when I started。一开始也不知道会做成什么样。不过总还是要去试，一开始是不知道未来会怎么样的。 So when I started as a software company, I expected to get maybe five employees and writing software. And just because we like to write software, I had a I think it's the tenth anniversary ceremony was 200 employees.
开张的时候，我想以后可能会有五名员工来写软件。因为我们喜欢写软件，所以在十周年庆典上，我们就有了 200 名员工。
And I told that particular story and ask the obvious question, what are you all doing here? Yeah, but yeah, but we also had a philosophy. We don't hire anybody, we can't pay, you know? So they were a side effect of the fact we were quite a cash cow. And it's much bigger cash cow now than it was then.
我讲了个故事，并问了一个问题：你们在这里做什么？我们付不起钱的人我们不请，你知道吗？所以是我们现金牛，现在的现金牛比以前大得多了
But to have predicted when I first started where it was going to end up. Don't even bother wasting the time. Go somewhere this interesting. Go somewhere that you can at least pay for your food and then push it beyond that. And if it doesn't work, find somewhere else, this don't try to predict life. It's, it's just, I think anybody here can probably test. Yet. You could never have predicted where you ended up with. I say to people, go to the master's level, but don't go beyond that until you go out and see what the real world is like and what's really needed. And that if you're really lucky or even if you're pretty good, yeah. The company will pay for whatever else they need from you because you are valuable. I keep emphasizing that. I don't think at the age we start out, we realize what a valuable resource we are. But the people who were working for, I hope, do.
但是浪费时间在刚开始的时候就预料它的结局。去一些有意思的地方，去一个你至少能付得起饭钱的地方，然后再超越它。如果不行，就去别的地方，不要试图预测生活。我想这里的每个人都能证明，你永远无法预料自己的结局。我说读个硕士就行了，走出去看看现实世界是什么样的、真正需要什么之前，不要越雷池半步。如果你真的很幸运，或者你很优秀，是的。公司会为他们需要你做的其他事情买单，因为你很有价值。我一直在强调这一点。我不认为在我们刚出道的时候，我们会意识到自己是多么宝贵的资源。但我希望为我们工作的人能够意识到这一点。
跟艾森豪威尔的一个完全相反的观点，但是也很有价值。艾的台词是，没有一场战争会跟着计划走，但是我们不能没有计划。Swanson的观点可以给安慰，价值量不如艾。
一个院长问了个问题David Erickson, director of Mechanical and Aerospace Engineering.
how you must have at some point made some mistakes early on in the day's events as well.
答： Well, let me be clear. There have been a lot more failures than successes. One success wipes out a whole lot of failures. 一俊遮百丑确实是很有价值的台词。
That's right, yeah, for example, I invested heavily in photovoltaics. I had a company and we had a goal up a dollar a watt. And that was an ambitious goal, is now 35, 40 cents a lot and the company doesn't exist. Yeah. So yeah, some things are within your control, some things are not. Now, I personally say we got to a dollar Watt were successful what B, and move on. So what, what's, what's the big learning then per? Well, that's a big learning is also a good money after bad. Good. Let it pull the plug at an appropriate time. Don't don't try to ride it all the way down. Like your memory. It'll give us another field isn't somebody who's very busy?
人总是不免失败的，睡一觉，把该忘的东西忘掉，继续搞点其他的东西。
问：They want to know what kinds of problems would inspire high-schooler to choose civil, mechanical, bioengineering today in all areas of engineering.
答：But I think, in my opinion, is engineering as the world's greatest career. And it's also one of the most respected. Now, let's please keep it that way. Yeah, don't, don't screw it up. Because engineers are what make the world work. I think the answer to that is yes, show people what engineering is. Show people what engineers do, show how exciting it is. Show him how much influence they have on the future and show him all that and they're not interested in it. He would probably it's probably a lost cause and move on to the next person.
但我认为，在我看来，工程学是世界上最伟大的职业。也是最受尊重的职业之一。现在，让我们保持这种方式。对，别，别搞砸了。因为工程师是世界运转的动力。我认为答案是肯定的，向人们展示什么是工程学。向人们展示工程师的工作，展示工程师的工作是多么令人兴奋。向他展示工程师对未来有多大的影响，向他展示这一切，但他们对此并不感兴趣。他可能会觉得这是个失败的事业，然后继续找下一个人。
怎么用ANSYS
问：So in terms of knowledge, the relation between knowledge and engineering, when you go to solve a problem, how do you get all the background information you need? Say to solve a problem or what are the key points that you target?
那么，就知识而言，知识与工程之间的关系，当你去解决一个问题时，你如何获得所需的所有背景信息？比如说，要解决一个问题，或者说实现你目标的关键是什么？
答：Let me go slightly sideways on that. When I first started teaching ANSYS, I said always start small. If you're going to go an auto crash analysis, you have one mass rep a car and one spring. Understand that? Then you can start modifying. You can put the mass on wheels and allow it to rotate a little bit when it hits a wall, and so on. So each, each new simulation should be a endorsement of what's happened before. Not a surprise. Yeah, if you get a surprise and simulation, you didn't understand the problem. Now, I'm not quite I think that relates to what your question was. And that is basically start at the start small and work your way up. Don't try to solve the big problem without understanding all the pieces to it.
让我换个角度答这个问题。当我第一次开始教ANSYS 时，我就说一定要从小处着手。如果你要进行汽车碰撞分析，你只有一个质量代表一辆汽车和一个弹簧。明白了吗？然后你就可以开始修改。你可以把质量放在轮子上，让它在撞墙时旋转一下，等等。所以，每一次，每一次新的模拟都应该是对之前发生的事情的认可。而不是意外是啊，如果你得到的是一个意外的仿真结果，那你就没有理解这个问题。这时候，我觉得这个分析与你的问题不太相关。也就是说要从小的方面入手，循序渐进。要就解决大问题，就要把所有的细节都搞清楚。
