Chapter 1000 Torch Group, the Eternal God (1 per day, asking for monthly ticket)

April 3, 29pm.

Because it was already the day before the official opening of the conference, all the special guests, even those who were not directly related to the competition, had already arrived in China.

At this time, a group of people were checking the finals scores with Chang Haonan at the backstage of the competition.

According to the competition rules, the final scoring of the finals needs to be witnessed by a group of specially invited guests and subject to random sampling.

Only after confirmation can it be announced and awarded at the conference the next day.

Different from the preliminary round where they have more time, for most teams, this problem in the final can only be completed about 6-8 hours in advance if there are no problems throughout the whole process.

If there is a shell stuck somewhere in the middle, time will seem very tight.

If we need to go back to work somewhere, we basically have to consider how to focus on the big things and let go of the small things.

Therefore, out of the more than 60 participating teams, more than 50 submitted their answers in the last half hour before the deadline.

As for the number of people who submitted their papers early...

After inspection, it was found that most of them had lost their minds and had given up hope.

Fortunately, there are not many teams participating in the finals, so even if they submit their works in large numbers, five hours is still enough to complete most of the scoring work.

"Good evening, Professor Chang."

Harold took the initiative to step forward and greet Chang Haonan.

After some greetings, the former suddenly looked around and asked:

"Speaking of which...why didn't I see Professor Jameson today?"

As a relatively unknown scholar, among all the special guests, he only knew the two people he met yesterday, so it was not surprising that he asked about Jameson.

"Uh... He said he wasn't feeling well, so he wanted to rest early and didn't attend the evening activities."

Chang Haonan tried hard to suppress his smile and replied with a regretful tone.

Of course, he wasn't lying.

Because that's exactly what Professor Jameson said.

However, as the instigator of everything, Chang Haonan knew a little bit about the inside story——

The other person is not feeling well, most likely because he is angry and is so angry...

"Well... tomorrow's meeting is indeed more important."

Of course, Harold had no idea what was going on and just took it for granted.

I was thinking, no wonder Professor Jameson seemed a little abnormal when I saw him the night before yesterday.

While the guests were talking to each other, Meng Weizheng, the head of the judging panel, stood up from his computer and strode to Chang Haonan:

"Report, all grading work has been completed!"

As the translator conveyed this sentence, the originally noisy computer room suddenly became quiet.

"Professor Chang, it's getting late. I think... stop keeping us in suspense and announce the results as soon as possible."

Professor Suhas Patankar from the University of Minnesota said.

As a numerical computing master who lived an era earlier than Anthony Jameson, Patankar can be said to be one of the original pioneers of the entire field.

Even as of 2002, his book "Numerical Calculation of Heat Transfer and Fluid Flow" is still the top textbook in the field of mass transfer dynamics, without a doubt.

It is natural for him to speak on behalf of the special guests.

Chang Haonan had no intention of keeping the secret at this time.

What's more, what is going to happen next is a trump card.

"Lao Meng."

He gestured to Meng Weizhen.

But a trace of hesitation flashed across the latter's face, and he whispered to Chang Haonan in Chinese:

"Boss Chang, the results of several groups are obviously abnormal. I'm worried... someone is deliberately causing trouble..."

I have to say that Meng Wei is really on high alert.

I just don't know how to judge the occasion.

Data anomaly?

Abnormal is normal, right?

If everything were normal, it would be abnormal...

"Do as I say!"

Chang Haonan said in a deep voice.

In the Torch Group, his prestige is still very effective.

Although Meng Weizhen was still a little nervous, he still followed Chang Haonan's instructions and turned around to ask the staff to project the results of the game.

At once, everyone turned their heads and looked at the curtain on the side of the room.

The most eye-catching one is naturally the first one.

"JingHang University...103.7 points!"

It must be said that the English names of some schools are set purely for the sake of setting.

For example, Beijing University of Aeronautics and Astronautics.

If foreigners do not understand Chinese, they will have no idea what "JingHang" means.

If you understand...

Then there is no need for an English name.

Fortunately, thanks to Chang Haonan, the name of JUAA is still somewhat well-known in the academic community, so it is not completely in the dark.

So someone recognized it quickly.

"I've read the papers published by Professor Chang. This should be the school where he works."

"Then it makes sense to rank first..."

"Indeed, if you are still Professor Chang's student, then..."

"Probably not. I remember Professor Chang specifically said before that his research group did not sign up for this competition in order to avoid suspicion."

"..."

As everyone was discussing, the list on the screen slowly slid down and the subsequent rankings gradually appeared.

Second place, National Higher School of Aeronautics and Astronautics.

Third place, Massachusetts Institute of Technology.

The scores of the two schools are exactly the same, both are 100.2 points.

The difference in the order of submission was just less than 10 minutes.

It's basically just a matter of luck.

"ISAE... the one in France?"

someone asked.

"of course."

The answerer was a French professor, and his tone was full of smiles.

Some universities in continental Europe are generally not known for their comprehensive rankings, but that does not mean they are not strong.

Fourth place, Samara State Aerospace University, 99.8 points.

Fifth place, Cranfield University, 99.4 points.

Sixth place, Ice City University of Technology, 98.9 points.

……

Except for a few Chinese names that occasionally flash by, the top ranked schools are basically schools that have already enjoyed a great reputation internationally.

Therefore, no one is surprised.

Only occasionally would a school where a particular person taught appear, and the crowd would burst into applause.

85.4th, Ohio State University, points

"Oh……"

Suddenly seeing Professor Harold from his school, he subconsciously covered his mouth, but still let out a cry of surprise.

Not many people present knew him, but when they saw this scene, they naturally understood that this was his school, so they gave him a polite round of applause.

The atmosphere seemed very harmonious for a while.

until…….

"and many more!"

When the list scrolled down to number 20, a voice suddenly sounded:

“So far, I don’t seem to have seen Stanford University, which is ranked first in the preliminary round, and the Minnesota Twin Cities, which is ranked third?”

In one sentence, it was almost earth-shattering.

Meng Weizheng, who was not far away, also shuddered when he heard this.

The abnormal grades he just mentioned are about this matter.

“I don’t think I saw it either…”

"really……"

"But this is already after the 20th place, and it only has 74.2 points... It's impossible for the two schools ranked in the top three in the preliminary round to perform poorly in the finals, right?"

The originally joyous atmosphere suddenly became a little subtle.

Since MIT ranks third and there are two other American universities in the top ten, it is impossible that the organizers are targeting the United States.

Since so many schools have seen a significant decline in their performance, it is obviously unlikely that there was cheating in the preliminary rounds.

However, who are the special guests? Someone soon saw the clues:

"It seems... that none of the schools that used COMSOL to submit engineering documents in the preliminary round have seen it?"

Now, the mystery is undoubtedly solved.

More than a dozen sharp eyes immediately turned to Chang Haonan.

Even Professor Harold was a little hesitant at this time.

"Professor Chang."

Finally, it was the highly respected Patankar who stood up:

"I think there are obvious irregularities in the final result."

The meaning is obvious -

If you are a businessman, you can take advantage of your status as the host country, play some tricks, and promote your own products. Everyone can understand this and no one will say anything.

But targeting competitors without any pretense is a bit too ugly.

As for Chang Haonan, he had to keep acting as they did, so he naturally had to continue acting with them:

“I agree with Professor Patankar.”

He put his hands behind his back and glanced timidly at the crowd:

“Therefore, it is recommended to conduct a thorough investigation!”

This dignified and righteous reaction was obviously beyond the expectations of others.

Even Patanka was a little confused. After a long pause, he said:

"Then... after all the rankings are released, we can check the result files submitted by those schools. You should have no objection, right?"

Chang Haonan thought to himself, I have no objection at all, I've been waiting for you to say this.

Check! Check now!

I can't let you out until I find out the result...

Of course, he still nodded with a serious look on his face, and replied in a decisive tone:

"Of course I have no objection."

"We must figure out why there is such a big difference in results between the preliminary round and the final round!"

After this little commotion, the screen finally showed the 40th place.

Starting from the 43rd place, the score column no longer contains numbers.

It is N/A.

No valid results.

The two schools just discussed are prominently listed in this list.

"No results?"

This result was completely beyond the expectations of everyone except Chang Haonan.

They originally thought that the organizer would give an extremely low score to the group using COMSOL.

But having no results is still a bit too outrageous.

Either it was not submitted at all, or a fatal problem occurred in some critical steps.

Otherwise, there has to be some distinction between high and low.

This time, everyone began to hesitate about their previous judgment.

Even if Chang Haonan really wants to cause trouble, he is not a fool.

How is it possible to see the problem at a glance using this method?

For a moment, the entire computer room fell into silence.

Finally, it was Chang Haonan who couldn't hold back any longer and took the initiative to speak:

"Everyone, time is running out, let's start the inspection!"

After he finished speaking, without waiting for anyone else to react, he turned around and looked at Meng Weizheng:

"Pick out the answers submitted by all teams after the 43rd place!"

"Yes!"

Seeing that Chang Haonan was still able to give orders in an orderly manner at this time, the latter finally realized that his boss might have already made a plan.

So this time, without any hesitation, I opened the first project file as I was told.

However, this one does not use COMSOL.

It is the software of Torch Group.

It took a group of bigwigs less than 3 minutes to figure out the problem.

I got the physical state wrong at the beginning, and then made a lot of low-level mistakes in the revision process. Finally, probably because my mentality exploded, I submitted an incomplete result a day earlier than expected.

Because it was submitted early, it is ranked first among N/A.

Next, comes the second one.

Or is it the software of Torch Group?

This is a bit embarrassing.

The situation is similar to the first one, I only did half of it and handed in a semi-finished product.

……

It was not until the fourth one that we finally had a file with the extension .cmph.

After opening it, even the style of painting is different from the previous ones.

At first glance, the file looks quite complete, and even tests several different models...

"How could this be..."

Someone blurted out subconsciously, thinking how could there be no results.

But the words got stuck in his throat.

Because everyone noticed.

Although the idea of ​​solving the problem is very reasonable, there are no major problems in program writing and selection of calculation methods.

But the most important thing is missing -

result.

It's not just that there is no final result.

There are not even intermediate results for testing the modeling.

Numerical computing competitions are not college entrance exams, there is no scoring based on steps.

So there is no result, the grade is N/A, which is very reasonable.

"But why..."

Harold's brain was a little burned out:

“Why don’t they calculate the results?”

He had no doubt that with the quality of the answer, as long as he got a relatively accurate result, even if it was not complete, he should be able to get a good ranking.

"Look at the back first."

Patanka waved his hand, stopping Harold from continuing.

At this time, his eyes had gradually changed from suspicion to curiosity.

The next one is Stanford University, which everyone pays most attention to.

Program loading...

Everyone held their breath almost subconsciously.

After a minute that seemed as long as a year, the project file was opened.

The situation is almost the same as the previous group.

Their ideas are clearer and their content is more complete.

But again, no results.

The third, fourth, fifth...

Gradually, people began to realize that something was wrong.

It is impossible for the submitted answers to be replaced.

Therefore, if one or two calculations using COMSOL yield no results, it can be considered a coincidence.

But all the answers submitted with COMSOL were fruitless, while others such as Torch Group and ANSYS were all fine...

The problem obviously lies with the computing tools.

Professor Patankar, a big shot who started his career in mass transfer dynamics, didn't waste any time and directly asked the staff to switch to the operation log.

Even as a special guest, few people can analyze log files directly with their naked eyes like Chang Haonan.

But Patankar is definitely one of them.

He saw the essence directly through the phenomenon:

"That is to say... COMSOL Multiphysics software will produce abnormal numerical fluctuations when calculating the viscoelastic constitutive equation... at least the specific viscoelastic constitutive equation, which will eventually lead to divergent results!"

He turned around and looked at Chang Haonan.

Only this time, the tone was questioning and seeking confirmation.

If this is true, then the applicability of COMSOL in two-phase flow, and even the entire chemical and energy fields, will be questionable.

At this time, Chang Haonan could no longer control his expression. He pinched his thighs a few times to barely hold back his laughter and put on a shocked face:

"It looks like... it should be like this."

"But... this... if this is a bug, it should have been discovered during the internal testing phase, right?"

To be fair, his acting skills are not very good.

But at this moment, everyone is still in the initial shock, so no loopholes have been discovered yet.

"and……"

Chang Haonan adjusted his mentality and continued to perform:

"And this kind of problem...can't it be solved using a constitutive equation that doesn't involve diffusion terms?"

"Could it be that COMSOL...hasn't done any research in this area?"

"?"

"?"

Everyone felt like something was wrong——

This is the technical route of COMSOL. Why do you, Torch Group, act like you know more about it than the real owner?
