Chapter 903 Reversely Recruit 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, on the contrary, secondary.

Of course, on the other hand, he really didn't know what the original arrangements for this ceremony were -

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.

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

This was the first time in his two lives.

In short, in his reply to Arthur Jeff, he first said 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 incompatible with his integrity and not speak out.

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

I just don’t know if the person on 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. After seeing this reply, he frowned slightly:

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

"yes."

Chang Haonan said, closing 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 study in BJ?"

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

"Hey...you are a foreigner, so nice."

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 person who receives the award."

"But having said that, because of what happened last year, Perelman and I don't have to accept this award, but the Clay Institute must consider it for its own reputation."

"So I can only find some decent ways."

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

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

There are those who think that $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, it’s probably time for all the hardships to 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 happened to receive a very interesting paper, so I sent it to you not far away."

The two shook hands as a farewell.

"It's okay, I understand the feeling."

After all, Yuan Xiangya is also an academic, and he knows that Chang Haonan 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 anymore. 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.

A flux Reconstruction Approach to High-Order Schemes 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.

To put it simply, 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 intra-unit polynomial reconstruction can be covered.

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

This is especially true for Chang Haonan.

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 the 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 computing field active, thus spawning a series of technologies that did not exist at all in the previous life, or did not appear until much later in the previous life. Results.

High-precision format is one of them.

In theory, the 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 reduced to 1/30000.

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

Therefore, 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.

It is only necessary for the user to set the flux correction function.

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

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

This is similar to the reason why the level set method is difficult to generalize.

High-precision formats have extremely high requirements on meshing accuracy.

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

Moreover, 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 relying on 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 topic, 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.

Therefore, 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 TORCH Multiphysics dares to set high prices.

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

After turning over one, there are two left.

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

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

It's a shield machine.

You can open a tunnel directly to come 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.

See if you 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 empty.

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's the beginning of the 21st century now.

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.

Therefore, going abroad or even immigrating is still a lifelong dream and goal for many people.

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

It's quite difficult.

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

Therefore, if you just send someone an email out of the blue, 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.

"Hey, Lao Song, it's me, Chang Haonan."

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

“Yes, it’s open to the whole world.”

“You can consider the specific form and arrangement. The funds will be mainly borne by the group. Of course, it would be better if others are willing to sponsor.”

“Well…if our friends are willing to participate, we welcome them with open arms!”
