The military-industrial scientific research system of the academic master.

Because he registered a few days later than others, the "new student gift package" that Chang Haonan received was obviously richer than others.

In addition to routine receipts, manuals, certificates and some small gifts, there are also all teaching materials corresponding to the first-year postgraduate course (and often the entire postgraduate period).

Although Chang Haonan probably won't need them.

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

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

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

In the more than a year since his rebirth, he has received a lot of achievements and honors, but when he saw his name signed on the cover of a large work, and it was also his own teaching material - and he was still the first, it was indeed first.

I have to say, it’s quite a novel feeling.

Naturally, the teacher in charge of student registration in the graduate department noticed the way he was staring at a book in a daze.

As an ordinary administrator, she certainly didn't know much about what Chang Haonan was involved in. She just felt that the students in front of her were attracted by this thick textbook, so she came over and took a look at the cover, and then showed an expression of sudden realization. .

"Oh? What a coincidence. The editor of this book has the same name as your classmate."

Obviously, the other party thought he had 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 his best to control his facial muscles, and at the same time put the books and all other things into his backpack as quickly as possible, then opened the door and left the office of the graduate department.

If he went any slower, he would worry that he wouldn't be able to hold on.

There was definitely no need for him to attend the class.

But the class still has to go.

After all, I had already promised Teacher Liu Hongbo before.

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

At the beginning, this course was originally planned to be called "Application of Finite Element Thought in Aircraft Structural Design". The focus was actually on the finite element idea and its mathematical foundation. Only a few actually talked about specific numerical simulation operations.

But later, as Chang Haonan expanded the content many times, the course was eventually expanded into a giant course that lasted for two long semesters and had up to 9 standard class hours per week.

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

After the TORCH Multiphysics software entered the development stage, he even added a lot of multi-physics simulations, new meshing methods and other related content into it.

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

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

At the end of the 90s, the importance of computers in various subject areas was not as common sense as it would be more than years later.

You must know that there are many foreign school candidates with relatively ordinary first-level academic qualifications who enter Beijing Airlines every year, and they have no opportunity to experience it directly at the undergraduate level.

Therefore, numerical simulation, especially numerical simulation in engineering, is the most important thing for them to establish the first impression of "this thing is awesome".

Of course, since there is only one teacher, Liu Hongbo, in the first year, he can only teach one major for the time being.

Although colleges and universities have been expanding enrollment during this period, college students are still relatively expensive in general. In addition, schools like Beijing Airlines have a good employment environment, so the entire college does not admit many graduate students in each session.

Chang Haonan didn't know the specific number of people this year, but he estimated that it would be about a few dozen people.

In university courses, it is not an exaggeration for a teacher to teach to 200 people, so this number of students is more than enough.

……

On the day of class, he came a little early. He was originally going to review the content with Liu Hongbo, but the latter hadn't arrived yet, so he found a seat not far behind him.

This was actually Chang Haonan's habit in his previous life.

Regardless of whether you are in the first row or the last row, it is easy to receive "key attention."

Only the middle is the most inconspicuous.

As a result, after waiting, Liu Hongbo didn't come, and more and more students came to class around him.

When there were about ten minutes left before class started, the room was almost overcrowded by 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.

The School of Aeronautical Science and Engineering alone obviously cannot gather so many people, and there must be many people from other schools joining in the fun.

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

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

In the late 90s, there was no academic administration system for course selection, so they really didn’t know about this course that they had never known before.

"Sigh... I haven't been in class for so long that I have 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 separated from student life for too long.

Nowadays, no matter how boring he is, he doesn’t have a smartphone to use. The laptop he brings with him is just for putting PPT and calculation examples in class. Because there is no wireless network, it is impossible to connect to the supercomputing center...

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

Just as he quickly opened the book to the chapter "Construction and Calculation of Equiparametric Finite Element Matrices", he suddenly felt someone next to him tap his shoulder lightly:

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

Chang Haonan didn't know how to answer this question for a while——

He didn't know whether the textbook he wrote was difficult or not.

After struggling for a while, I had to give a one-size-fits-all answer:

"I think it's okay. Listen to the lectures carefully, 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 classmates who went to some schools that their postgraduate courses only have a total of 300 class hours..."

In the midst of awkward chats, Liu Hongbo finally walked into the classroom five minutes before class with a thermos cup in hand.

The moment he pushed the door open, he was obviously shocked by the "grand occasion" inside.

Liu Hongbo, who was taking this course for the first time and was not very confident, even showed a somewhat overwhelmed expression 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 sitting in the middle row with a computer on the table that I finally breathed a sigh of relief.

It's just that in the eyes of his classmates who didn't know what he meant, he definitely looked like a boss.

What's more, the name of Teacher Liu Hongbo is written on the cover of my extremely thick textbook.

Although ranked second.

But it’s the editor after all, right?

Therefore, the atmosphere in the entire classroom quickly became quiet.

"Cough cough..."

Liu Hongbo cleared his throat:

"I am very happy to teach you this course on numerical simulation principles and methods. You are very lucky, and I am also very lucky, because I dare not say it internationally, but this is definitely the first time that a university in China has offered a similar course. 伱We will also be the first batch of students to systematically study numerical simulation methods..."

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

Having said this, he has already raised the expectations of the students below.

After all, it seems that the editor-in-chief named Chang Haonan who is ranked first is probably a very senior old professor.

Even academicians.

However, what Liu Hongbo said next 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 by my junior brother and your classmate, Chang Haonan!"

As soon as he finished speaking, the classroom exploded.

"what?"

"seriously?"

"Is this the difference between people? The textbook I used when I was a graduate student was actually written by my graduate student classmate?"

"I seem to have heard this name somewhere before..."

"Chinese Youth May Fourth Medal? Are you one of the winners?"

"..."

And when Chang Haonan stood up and walked to the podium with his computer, the person who had just been chatting with him next to him almost jumped up from his seat:

"I really believed his lies. It's not that difficult. He's the author. Of course it's not difficult..."
