Because he reported a few days later than everyone else, Chang Haonan received a "freshman gift package" that was obviously richer than others.

In addition to the usual slips, manuals, certificates, and a few small gifts, there are all the textbooks for the first year of graduate school (and often the entire graduate school).

Although Chang Haonan probably doesn't need them.

Naturally, this also includes the numerical calculation textbook edited by himself.

"The quality of this book is pretty good......

Looking at the beautifully bound cover, Chang Haonan felt a somewhat strange feeling in his heart.

In the more than a year since his rebirth, he has won a lot of achievements and honors, but it is indeed the first time that he has seen his name signed on the cover of a large work, and it is also his own textbook - and it is the first place.

I have to say, quite a novel feeling.

His staring at a book in a daze was naturally seen by the teacher in charge of student registration in the graduate school.

As an ordinary administrator, of course, she didn't know that Chang Haonan was involved in too many things, but she just felt that the students in front of her were attracted by this thick textbook, so she also leaned over and glanced at the cover, and then showed a sudden expression.

"Oh? It's such a coincidence, the editor of this book has the same name as your classmates. ”

Obviously, the other party thinks that he has grasped the key to the matter.

Although there is no mirror, Chang Haonan believes that his expression must be wonderful at this moment:

"Ah, yes, what a coincidence."

He tried to control his facial muscles as fast as he could, loading the book and everything else into his backpack before pushing the door open and leaving the graduate office.

No matter how slow he was, he was worried that he wouldn't be able to hold it back.

class, he definitely didn't have to go to it.

But the class still has to be taken.

After all, I have promised Mr. Liu Hongbo before.

Because Chang Haonan reported a few days later than others, for him, it was almost followed by a section of Mr. Liu Hongbo's "Principles and Methods of Numerical Simulation (1)".

At the beginning, this course was originally planned to be called "Application of Finite Element Thinking in Aircraft Structure Design", but the focus was actually on finite element thinking and its mathematical basis, and there were actually a few people who really talked about specific numerical simulation operations.

But later, with Chang Haonan's multiple expansions of the content, the course eventually expanded into this giant course that lasted for two long semesters and had as many as 9 standard class hours per week.

The main content has also been upgraded from just allowing students to understand and expose themselves to the finite element method to a one-stop solution from basic theory to practical application.

When TORCH Multiphysics entered the development phase, he even added a lot of multiphysics simulations and new meshing methods to it.

As for the potential teaching objects, it has also expanded from the School of Aeronautical Science and Engineering to all science and engineering majors in the entire Beijing Airlines University.

According to Chang Haonan, it is to strive for students who have completed this course and understood this course to directly enter the practical application stage.

At the end of the 90s, the importance of computers in various disciplines was not as common knowledge as it was more than 20 years later.

You must know that every year, there are many foreign school candidates who enter Beijing Airlines for graduate school with relatively ordinary first degree, and they have no opportunity to feel intuitively at the undergraduate level.

Therefore, numerical simulation, especially in engineering, is the core of letting them establish the first impression of "this thing is really awesome".

Of course, because there was only one teacher in the first year, Liu Hongbo could only teach one major for the time being.

Although there has been a trend of expanding enrollment in colleges and universities during this time period, college students are still relatively expensive on the whole, and the employment environment of schools like Beijing Airlines is good, so there are not many graduate students admitted by the entire college each year.

Chang Haonan doesn't know the specific number of people this year, but it is estimated that there are dozens of people.

In a university course, it is not an exaggeration for a teacher to give a lecture to 200 people, so this is more than enough for students.

……

On the day of class, he came a little early, and was going to check the content with Liu Hongbo, but the latter hadn't arrived yet, so he found a position to sit down.

This is actually Chang Haonan's habit in his last life.

Both the first and last rows are susceptible to "focus." ”

Only the middle is the most inconspicuous.

As a result, Liu Hongbo didn't wait, but there were more and more students around him who came to class.

By the time there were about ten minutes before class, the room was about to be crowded with the crowd inside.

Not to mention the seats, there were quite a few people sitting on the floor between the podium and the first row of desks.

Obviously, one school of aeronautical science and engineering alone can't get together so many people, and there must be many other colleges to join in the fun.

And many second- and third-year graduate students should also arrive.

Because Chang Haonan saw Yao Mengna in the first row in front of him closest to the podium.

At the end of the 90s, there was no academic system for course selection, so I really don't know what they ever knew about this course.

"Alas...... I haven't been in class for too long, and I've forgotten that university teachers are used to stepping on the bell to enter the classroom......"

Chang Haonan couldn't help but sigh, feeling that he had been out of student life for too long.

In these days, no matter how boring he is, there is no smartphone to brush, and the laptop he carries with him is only for PPT and calculation when he will be in class, because there is no wireless network, so it is impossible to connect to the supercomputing center......

In short, in the end, he was bored, so he could only open the book in his hand that he had read several times before it was published, and revisit it.

Just as he was rapidly turning the book to the chapter "Construction and Computation of Isoparametric Finite Element Matrices", he suddenly felt someone next to him gently pat him on the shoulder:

"Classmate, this course should be quite difficult, right?"

This question made Chang Haonan not know how to answer for a while-

He didn't know if it was difficult for him to write this textbook.

After struggling for a while, I had to give a panacea answer:

"I think it's okay, listen to the lectures well, read more books, and go to the computer room to practice more, it shouldn't be difficult."

"To be honest, I have never taken a class with so much content, 288 class hours, and I heard from my classmates who were admitted to some schools that their graduate courses only had about 300 class hours in total......

In an awkward chat for a while, Liu Hongbo finally held a thermos cup and walked into the classroom 5 minutes before class.

The moment he pushed the door in, he was obviously surprised by the "pomp" inside.

It was also the first time to take this class, and Liu Hongbo, who was not very confident, even showed an expression of some confusion on the podium for the first time.

So after standing on the podium, he first looked around the classroom twice.

It wasn't until I saw Chang Haonan, who was sitting in the middle row with a computer on the table, that the whole person finally breathed a sigh of relief.

It's just that in the eyes of his classmates, who don't know the so-called classmates, it is definitely the style of a big guy.

What's more, on the cover of his thick textbook, the name of this teacher Liu Hongbo is still written.

Although it is in second place.

But it's the editor, isn't it?

As a result, the atmosphere in the classroom quickly fell silent.

"Ahem......"

Liu Hongbo cleared his throat:

"I am very happy to give you this course on the principles and methods of numerical simulation, you are very lucky, and I am also very lucky, because I dare not say it internationally, but this is certainly the first time that a university in China has opened a similar course, and you will also be the first batch of students who have systematically learned numerical simulation methods......

"However, today's first lesson is not for me to tell you, you should have noticed when you get the textbook, I am one of the editors of this textbook, but there is another one in front of me."

Speaking of which, he has already filled the sense of antiquity of the students below.

After all, from this point of view, the editor-in-chief named Chang Haonan, who is ranked first, is likely to be a very senior old professor.

Even academicians.

However, Liu Hongbo's next sentence was beyond everyone's expectations:

"The real editor-in-chief of this book happens to be sitting among you today, so this class will be taught to you by my junior brother and your classmate, Chang Haonan!"

As soon as the words fell, the classroom exploded.

"Huh?"

"Really?"

"Is this the gap between people and people, the textbooks I used when I was in graduate school were actually written by my graduate students?"

"I think I've heard this name somewhere before......"

"Chinese Youth May Fourth Medal? One of the winners, right? ”

“……”

And when Chang Haonan stood up and walked to the podium with the computer, the person who was chatting with him just now almost bounced up from his seat:

"I really believe his nonsense, it won't be difficult, he TM is the author, of course I don't think it's difficult......"
