Chang Haonan's major actually didn't have many classes in the second semester of his junior year, so although the next day was a Monday, he still had half a day of free time in the afternoon.

And Zhou Shuwan and Zhang Man directly skipped a section of Mao in the morning, and calculated the design scheme corresponding to the half cone angle of the first precursor in the library, so after class, Chang Haonan went to the cafeteria to simply pick up two mouthfuls of food and went straight to the computer room with the calculation results and the student ID cards of four people.

However, things did not go as smoothly as Chang Haonan imagined.

The next task was not difficult for him, but it was not easy for the computers of this era, especially since the fifth step of the design work, which was to generate the internal profile of the air intake, was completely carried out by the computer.

Therefore, after he used up today's 4 hours of time on the plane, he finally built the nose model of the first plan, and he didn't even have time to combine it with the fuselage.

And the capacity of the two floppy disks that Yao Mengna lent them has also run out, after all, the capacity of each one is only 2.88MB, and the project file is full when two are stored.

"When I have resources in the future, I must get the USB flash drive out in advance, it's too troublesome......" Chang Haonan, who was politely invited out of the computer room by the management teacher, shook his head and thought to himself.

While eating dinner in the cafeteria, Chang Haonan told the other three people about the situation.

There is no problem in completing it before the deadline, but there is no need for Zhang Man and Zhou Shuwan to fight so hard.

Correspondingly, considering the short time from the completion of the design plan to the delivery, Wu Yifan, who was in charge of the text, needed to start early and complete the design work in parallel with Chang Haonan.

Of course, the latter has the final say on what to write and how to write, and Wu Yifan only needs to be a ruthless writing and drawing machine.

……

Just as Chang Haonan was eating and assigning tasks, at another dining table not far from them, Yao Mengna was also chatting with two classmates in her laboratory about the progress of the project.

Although she was hit by Chang Haonan last night and doubted her life, as a doctor, her first reaction after encountering a problem that she couldn't do was, of course, it was impossible to give up, so today I went to the library to borrow some books about the DAMP language and the dipole grid method, and went to the Internet to find some information, although it is certainly impossible to fully understand it in one day, but at least I can be sure that this idea is worth trying.

"Dipole Grid Method......" Sitting opposite Yao Mengna was a boy with a polite temperament and thick hair that didn't look like a doctor: "Senior sister, are you really sure?" Although the CFD/CSD coupling method we used before was very inefficient, the accuracy has been continuously improved after continuous correction of the method, and the project was hastily reversed and restarted when the project time was more than halfway through......"

"Fang Bo, we all know very well that there is no future for continuing to make small repairs according to the original ideas." Yao Mengna put the chopsticks on the plate, raised her head and looked at the boy named Fang Zhen in front of her.

"Although the accuracy is improved by 15-20% compared with the beginning, it can indeed be used to conclude the problem as an achievement, but such a large amount of calculations, it is also necessary to manually adjust the parameters for each example, which is essentially shooting arrows first and then drawing targets, which has no guiding significance for engineering practice, and we as scientific researchers should not be satisfied with this, especially now that I am very sure that the dipole grid method is feasible, but I just need to learn something new."

Although Fang Zhen, who is a Ph.D., seems to be only one year older than Yao Mengna, who is a Ph.D., he skips the master's level and directly studies for a doctorate, so Fang Zhen is actually much older.

However, once it comes to research-related matters, let alone senior brothers, even in the face of mentor Yao Mengna, she has never been easily convinced.

Seeing such a posture, another thin girl next to her, who was not tall, quickly diverted the topic: "Speaking of which, Senior Sister Yao, how did you suddenly come up with this new idea?" I've never heard you say it before, so I saw you bring back a bunch of books from the library today. ”

Compared with Fang Zhen and Yao Mengna, the two doctors, this girl named Summer is just a first-year master's student, and it doesn't matter which technical route she takes, the top priority is to stabilize the two optimus jade pillars in the group, and definitely not let them quarrel with each other.

However, this casual question directly asked Yao Mengna in place.

"Yes...... I asked from a senior who happened to have done a similar project before. Yao Mengna took a deep breath, touched the tip of her nose and replied.

Originally, Yao Mengna was not a person who wanted to save face, and it was nothing to say that she heard it from her junior brother.

But firstly, this is not convincing enough, and secondly, is it ......

Chang Haonan's tone, which was like a teacher treating elementary school students, really made her look back.

"Senior? Are there other research groups in our school that are working on similar projects? Fang Zhen was also stunned, you must know that even undergraduates are rare in these years, and the number of graduate students is even less, and the research groups of a college know each other more or less.

"Oh, it's my senior when I was an undergraduate, and he's no longer in BJC." Yao Mengna had to bite the bullet and continue to make it up.

Fortunately, neither Fang Zhen nor Xia Zhen got to the bottom of this issue.

"Then it's better like this, junior sister in the summer, you will take over the work of CFD/CSD, anyway, Yao Bo and I have already built the framework, as long as it is done step by step, the two of us will try to see if we can go through the dipole grid method." Fang Zhen quickly found a compromise solution: "At least this can ensure that there are results by the end of the year, and it would be better if the new method could work." ”

Because Du Yishan is very resourceful and is not in school most of the time, and the other teachers in the same group are very young, and they have not even stayed in the school as long as these doctors, so Fang Zhen, as a senior brother, has to bear some management responsibilities in addition to scientific research, which causes him to be more conservative in many cases.

"Okay, that's it." Yao Mengna nodded, and it was a plan after accepting this compromise.

Only the summer next to her, who had not had time to express her position, was dumbfounded, and the speed of the reversal of the situation was completely beyond her imagination.

How did I, a first-year master's student, get assigned to a CFD/CSD position?

The words are divided into two ends, and the matter is one side.

To Chang Haonan's expectation, he didn't see Wu Yifan all day the next day, and according to the agreement, the latter should go to the computer room to start preparing to write a script.

The third day, all day and still nothing.

This even made Chang Haonan a little worried, in his impression that although Wu Yifan was not interested in professional content, he would still do what he promised others.

Early in the morning of the fourth day, just when Chang Haonan had begun to hesitate whether to find a counselor or even call the police, Wu Yifan finally appeared.

"Nanshen, didn't you say before that the time and floppy disk storage space are not enough?" Wu Yifan mysteriously took off his schoolbag and put it on the table, and then opened the zipper to Chang Haonan. "I got a laptop and a new box of floppy disks."

Chang Haonan looked at the IBM classic tricolor mark in front of him with a shocked expression.

He suddenly felt that it was not a bad thing to have such a friend who was obsessed with business and did not care about his studies.

"Where did you buy it?" Chang Haonan turned on the computer and saw that the keyboard was divided into two parts with the action of opening the screen, and then combined again.

IBM 701C, which is almost a collector's model in later generations, is estimated to cost tens of thousands of yuan if you want to buy it at this time.

Tens of thousands of dollars in 96!

"I knew a senior from Huaxia Renmin University when I was running a business before, and in my senior year this year, I lost a lot of money when I opened a restaurant outside, so I processed the computer to me and returned the funds, and I also asked him to install the two software you used in the past two days."

The story that Wu Yifan said Chang Haonan seemed to be a little familiar, but he couldn't care about it now, so he quickly took out his laptop and took out the two floppy disks containing engineering documents.

Open the liver!
