The Military-industrial Scientific Research System of the Academic Master Chapter 903

Chapter 903: Poaching talents from the United States!

As far as Chang Haonan is concerned, as long as the other party agrees to hold the award ceremony in China, everyone will be happy.

The issue of face is secondary.

Of course, on the other hand, he really didn't know what the original arrangement of this ceremony was—

The proof process of the Poincaré Conjecture in the previous generation did not cause a stir of public opinion like last year, so Perelman successfully refused to accept the award in the end.

So, there is actually no prize for the Millennium Mathematical Puzzle.

This is the first time in his two lives.

In short, in his reply to Arthur Jeff, he first stated that "the venue of the award ceremony cannot be adjusted at will according to the request of the winner", but then turned around and said that "the award ceremony will be held at the nearest International Congress of Mathematicians" "Chang Haonan finally chose to see through this kind of behavior that was inimical to his integrity but not speak out.

He also wrote back and highly praised the efforts made by the Clay Mathematics Institute in reducing extravagance and waste and practicing thrift.

I just don't know if the person at the other end of the network cable will vomit blood after seeing it...

However, Yuan Xiangya's reaction next to him was still a little slow, and he frowned slightly after seeing this reply:

“Professor Chang, isn't the 'nearest International Congress of Mathematicians' the one next year?”

"yes."

Chang Haonan said as he closed the email receipt interface, and then clicked on an email from the inbox again.

　Judging from the domain name, it should be from Ohio State University.

"But I remember...next year's class is already close to ten, and it's decided to open in BJ?"

Yuan Xiangya obviously still lacks some deep understanding of the attribute of "tsundere".

“Hey…foreigners, good face.”

Chang Haonan shook his head helplessly:

“If I ask them to present the award in the capital, the other party will definitely not agree directly. After all, there is no reason for the person who gives the award to be manipulated by the recipient.”

“But having said that, because of what happened last year, Perelman and I can refuse to receive this award, but the Clay Institute must not refuse to award it for the sake of its own reputation.”

“So I can only find some decent ways.”

Yuan Xiangya felt that his visit today was not in vain.

He had seen more anecdotes in that hour than in the previous ten years combined—

Those who think that US$500,000 is a hot potato, and the award organizers who are begging to give money to the winners.

However, it is always a good thing.

The Chinese mathematics community has never been so proud as it is today—

More than half a century ago, there were some systematic achievements in theoretical mathematics in China.

However, as a poor and weak country at that time, China was inherently unable to make a big noise in the international arena.

This is true in any field.

Later, the Chinese people stood up.

As a result, Huaxia Mathematics fell again...

In short, it just didn't catch up with the good times.

But now, probably all the hardships will come to an end...

Looking at Chang Haonan who was immersed in work again, Yuan Xiangya suddenly felt that even though he had passed the best age for achieving results, it seemed that if he changed his route, he would not be able to do something more...

“Then I won't disturb your work.”

Thinking of this, Yuan Xiangya stood up and prepared to leave.

This time, Chang Haonan just sent him to the door of the office:

“I just received a very interesting paper, so I will send it to you not far away.”

The two shook hands as a farewell.

“It's okay, I understand how it feels.”

Yuan Xiangya is also an academic after all. Knowing Chang Haonan, this is definitely not an excuse:

“It's very annoying to have your train of thought interrupted while reading a paper. I won't be such a bad person. Goodbye.”

After sending Yuan Xiangya away, Chang Haonan almost jogged all the way back to the computer.

The paper on the screen that was highly praised by Chang Haonan was naturally from the research group of Professor Harold Huang.

AfluxReconstructionApproach toHigh-OrderSchemesIncludingDiscontinuousGalerkinMethods (High-order flux reconstruction methods including discontinuous Galerkin methods).

Chang Haonan was attracted almost as soon as he saw the title of the paper.

After reading the abstract and highlight, he was basically determined to accept this article.

Simply put, Professor Harold unified a series of compact and high-precision formats that have emerged in recent years through a method called "high-order flux reconstruction (FR.

As long as different flux correction functions are selected in the FR method, almost all high-precision formats based on intrunit polynomial reconstruction can be covered.

It can be said that this achievement is equivalent to the "grand unified theory" in its subdivision.

Especially for Chang Haonan, this is even more true.

High-precision format has been a very hot research direction in the past two years.

However, this has nothing to do directly with Chang Haonan himself or Torch Group.

If I have to say something, it can only be said that the emergence of the catfish TORCH Multiphysics has made the entire numerical calculation field active, thus giving birth to a series of achievements that did not exist at all in previous lives, or did not appear until much later in previous lives. .

High-precision format is one of them.

Theoretically, its advantage is that when sufficiently high-precision meshing is used, the calculation error can be controlled to a very, very low level.

Or in other words, if such a low calculation error is not required, the number of grids can be greatly saved. Taking the level set method studied by Chang Haonan as an example, when the error constraint is 1e-6, the grid size corresponding to the fourth-order high-precision format is 32 times the grid size corresponding to the second-order format.

In the three-dimensional case, the mesh amount can be saved to 1/30000.

In this case, the additional complexity introduced by the high-precision format itself is basically negligible.

However, the application scope of each high-precision format is quite narrow and the complexity is very high. If each format is written into the software separately, the amount of code data will increase to an unacceptable level.

And many complex engineering models cannot be processed in one format at all.

Hence, the current official version of the software has not included high-precision formats in the update plan.

The FR method, if it is what the author said, can solve this problem perfectly.

As long as the user sets the flux correction function.

As for why such a significant paper was published to JCAS... Chang Haonan can probably guess it.

Although the FR method solves the problem of "narrow application range of a single method", in order to truly realize its application, two other obstacles must be overcome -

Similar to the reason why the level set method is difficult to generalize.

High-precision format has extremely high requirements on meshing accuracy.

If the mesh is rough, the results of the high-precision format may be worse.

Furthermore, due to the relatively poor adaptability of high-precision formats, it also requires high levels of engineers using CFD software.

Even with FR, it is impossible to solve some simple problems just by software presets like traditional low-level methods.

This is the case in the field of numerical computing. Different people use the same software tools to complete the same project, and the results are often very different.

However, in the current initial stage of the development of the CFD industry, the level of the vast majority of users is difficult to describe.

Hence, the industry is generally not optimistic about the short-term development prospects of high-precision formats.

Even Chang Haonan was like this before today.

It's just that he is two steps ahead of others -

Torch Group not only has the only meshing algorithm in the industry, but also has a numerical computing business department dedicated to "after-sales" and even holds regular numerical computing business training.

This is also one of the core reasons why TORCMultiphysics dares to set high prices.

In other words, there are three big mountains facing competing products.

Turn over one and there are two left.

But Chang Haonan was already standing in front of the third mountain, and it would be a smooth road after climbing over another mountain.

The FR method in front of me is not even a trekking pole.

It is a shield machine.

Can directly open a tunnel out...

Thinking of this, he quickly threw the paper into the folder where it was published in the first issue, then picked up the phone on the desk and prepared to ask the Torch Group office to send an email to Professor Harold in the name of the company.

Let's see if we can poach the opponent directly.

However, after pressing two numbers, his right hand was hanging in the air again.

˜Due to the interruption of the dialing action, the receiver soon sounded a tone indicating that the phone number was unavailable.

After struggling for a moment, Chang Haonan put down the phone again.

Although Torch Group has gained a certain reputation in the industry, in the final analysis it is still a Chinese company.

It is now the beginning of the 21st century.

Even though Chang Haonan has used various means to make China develop much faster than in the previous life, for people who have not experienced the two timelines, this contrast cannot be felt.

So, going abroad or even immigrating is still the lifelong dream and goal of many people.

And poaching people from developed countries, especially the United States, which seems to be still at its peak at this time...

It's quite difficult.

Affected by the propaganda from the United States, China's image in the eyes of Americans, if not still at Daiqing, is at least not much different from that of a large South Asian country.

So, if you send someone an email so suddenly, I'm afraid the effect won't be very good.

Still need to lay the groundwork.

Furthermore, Chang Haonan also had to confirm whether Harold Huang really had ink in his stomach.

After all, the journal editorial office is not responsible for the authenticity of the content of the paper.

But as a leader, he must be responsible for the development of the company.

With this in mind, Chang Haonan had a new plan in mind.

So, he picked up the receiver again and quickly dialed the number of the Torch Group's office.

“Hello, Old Song, it's me, Chang Haonan.”

“You remember to make arrangements. When the TORCH Multiphysics 2.0 version is officially released in the second half of the year, we will hold a conference on numerical algorithms and computational science.”

“Yes, for the whole world.”

“You can consider the specific format and arrangements, and the group will be the main bearer of the funds. Of course, it would be better if someone else is willing to sponsor it.”

“Well...if friends and businessmen are willing to participate, we welcome them with both hands!”
