After returning to the conference room and sitting down again, Liu Yiming found that the deputy leader of the review team, Li Hang, an old acquaintance from Northwest Industries, looked like he was hesitant to speak, which was quite interesting.
"Lao Li, if you have anything to do, just tell me!"
"Old Liu," Li Hang leaned his head sideways, lowered his voice, and whispered, "I just discovered that when they designed, they used special engine design software. It seems that they can call a lot of professional software to assist at any time, such as flow field
Calculation, finite element analysis, structural calculation..."
"I know this," Liu Yiming raised his head and glanced at the projection in front of the conference room. "The industrial software company jointly owned by Xinghan and Qingyan has launched several products, and our school has started to promote them..."
"What's the matter, Lao Li," Liu Yiming turned around and looked at his old partner cheerfully, "Are you tempted? I'll set you up with a lead tonight and have a private chat?"
"Thanks then..."
The review in the morning was limited to the framework, national standards and calculation reference books involved in the company's design process.
In the afternoon, the review entered the substantive stage, and the first one was naturally the computing framework.
Qingyan Aviation's thermal, heat transfer and strength calculations and formula frameworks are all automatically generated by the software, so there is no doubt about their orderliness.
However, there are many calculation details involved, such as some more corrections and insurance coefficients than in the calculation reference, which are more troublesome to explain.
Of course, there are also precise calculations of some coefficients...
"Experts, I can only tell you how many to choose. As for how to choose, it involves the company's intellectual property rights..."
Although Xinghan is hiding it, the reviewers are all experts in the industry, so they can naturally get a glimpse of the computing software from the computing data.
Especially Liu Yiming, after looking through the calculation data carefully, he raised his head and glanced at Zhou Yan: "Zhou Yan, have you put the N-S calculation principle that you sent to the journal a while ago into practical use?"
"I know I can't hide it from the teacher," Zhou Yan smiled and nodded, "I will give examples of some of the specific applications and send them to domestic journals."
Although the people sitting here are all top experts in the field of aviation design, they have been in the industry for many years after all, and they know what it means to be human and sophisticated: in subsequent reviews, if similar value problems are encountered again, as long as they are within a reasonable range,
Never ask any more questions.
Although Qingyan's internal internal audit only took one day, it was a self-examination after all, and a pervert like Zhou Yan, who could read ten lines at a glance and make quick calculations, could not find anyone else.
The review by the expert group is naturally much more detailed than the self-review, and the speed is naturally much slower.
After reviewing it for a whole day, I only reviewed the overall framework.
After getting off work in the afternoon, Zhou Yan and Xu Chongsheng sent the experts to their hotel together.
After leaving the hotel, the car had just driven a few hundred meters when the cell phone in his pocket suddenly rang. Zhou Yan had to take out his Bluetooth headset and put it on.
"Hello!"
"I'm Liu Yiming."
"Oh, teacher, I'm on my way, what can I do?"
"Are you free tonight? I'll treat you to dinner with Xiao Qin! The treasure gathering place at the west gate of Jiaotong University! Drive carefully, I'll hang up first!"
Before Zhou Yan could say anything, there was only a busy tone on the phone.
When I got home, I made a phone call before going upstairs: "Hi, wife, are you at home?"
"No, I'm here at Houhai!"
"If you haven't eaten yet, stop working now. My teacher is treating you to a treat and asked me to call you. I guess there's something going on."
"Okay then," Qin Ruoshu thought about it for a moment, "come and pick me up..."
After bringing Qin Ruoshu back and tidying up again, the two of them went out.
After arriving at the hotel and finding a seat, Zhou Yan discovered that his teacher seemed to have returned love to someone else.
"Professor Li?"
"Here you are, just sit down," Liu Yiming smiled and pointed to the seat next to him, "Old Li, I don't need to introduce Zhou Yan. This little girl is Zhou Yan's partner and we got married last summer."
"Hello, Teacher Li!" Qin Ruoshu said crisply.
"Zhou Yan," after the two sat down, Liu Yiming stared at Zhou Yan with a smile, "The old man's salary is limited and he can't afford to hire someone too expensive. I feel aggrieved..."
"Teacher, what you said reminds me of a joke," Zhou Yan continued, suppressing a smile. "It is said that in ancient times, there was a couple in a certain dynasty. Because they had never met the emperor, they fantasized about what the emperor's life was like.
One of them said that the emperor cultivated the land with a golden hoe. Another person thought that there must be countless silkworms in the queen's silkworm room..."
Then, everyone sitting there was happy.
"Actually, we, as a couple, cook by ourselves every day. As you said, we cook abalone and sea cucumber every day..."
"You kid, you are secretly mocking me, right..." As he said, Liu Yiming glanced at the hot pot, "It's coming soon, put the mutton first..."
"Speaking of which," Liu Yiming saw Zhou Yan staring straight at him, waiting for an answer, and said with a smile, "Lao Li and I met in Tianfu. At that time, we had just received our intermediate professional titles. At that time, I
The two are competing for the same project..."
The comrades-in-arms relationship in the 1970s included fierce conflicts, pure friendship, mutual appreciation, and dissatisfaction with each other, but there were no messy thoughts...
Zhou Yan, who is familiar with the routine, knew clearly that the teacher was foreshadowing or endorsing Li Hang who was opposite him.
"Teacher," Zhou Yan glanced at Liu Yiming, "Speak directly if you have anything to say. There is nothing that we, master and disciple, cannot say..."
"Then I just said it?" Liu Yiming glanced at Li Hang with a smile and said, "My old brother has taken a liking to your company's aviation design software..."
"That's easy to say," Zhou Yan smiled. "After the design review is completed, I will ask the software company to sort out the software and give it to Teacher Li."
"What if it is used in school?" Li Hang asked impatiently.
"Teacher Li," Zhou Yan raised his head and stared at the other party cheerfully, "at the university level, it is basically useless because the foundation is not solid. If you use it, it will be like wasting four years. As for graduate students, Teacher Li, you can do it in one year
How many aerospace engineering graduates can NWIT have each year?"
"Indeed..." Li Hang smiled coquettishly.
"Our software has very high configuration requirements. It must be a server with at least four dollars." Zhou Yan looked at Li Hang with a smile. "Let's do this. I will give you twenty serial numbers. How to install it? How to install it?"
Wherever you go, make your own arrangements."
"Thank you then. I'll give you tea instead of wine to express my gratitude..."
"Teacher Li, please don't rush to thank us. It's a bit ugly. We have to talk about it at the beginning." Zhou Yan smiled and picked up the tea cup. "This software is easy to use here, but it doesn't mean that it will be good for you to take it back."
In order to enrich the database of the software, we have spent a lot of effort here. Some of the design data is impossible for our company to transfer externally."
"That's true," Li Hang nodded, "What if we enrich the database ourselves?"
"It's best to find professionals and take good protection." Zhou Yan glanced at the hot pot and saw the water boiling. "Even pneumatic and thermal data must be physically isolated from the network..."
"Our school's firewall and data protection are pretty good..." Li Hang nodded, "By the way, Zhou Yan, in the afternoon, I saw that your aviation engine's aerodynamic and thermal calculation data seemed to be based on the same
Made from models..."
Li Hang suddenly stopped mid-question, a little embarrassed: "This doesn't involve your company's secrets, does it?"
"There is nothing to keep secret," Zhou Yan smiled and shook his head, "Our company actually uses a stupid method, finite element, to divide the flow field into points, but there are many points to choose from, and finally use formulas to unify them to form an organic
overall……"
After listening to Zhou Yan's explanation, Li Hang realized that the N-S equation that Zhou Yan sent to Nature magazine in the autumn was already very mature in its application within Qingyan.
