Chapter 1000 Torch Group, Eternal God (10,000 per day, please vote for me)
March 29, 8pm.
Because it was already the day before the official opening of the conference, all special guests, even those not directly related to the competition, had already arrived in China.
At this time, a group of people were backstage at the competition, checking the scoring of the finals with Chang Haonan——
According to the rules of the competition, the final scores of the finals need to be determined by the special guest group. Conducted under witness and subject to random inspection.
After confirmation, the awards will be announced and awarded at the conference the next day.
Unlike the preliminary rounds, which have relatively ample time, for most teams, the finals can only be completed about 6-8 hours in advance if there are no problems throughout the process.
As long as the shell is stuck somewhere in the middle, time will appear to be tight.
If you want to rework somewhere, you have to consider how to focus on the big and let go of the small.
Therefore, among the more than 60 participating teams, more than 50 submitted their answers in the last half hour before the deadline.
As for those digits that were submitted in advance...
After inspection, it was basically the result of a broken mentality.
Fortunately, the total number of teams participating in the finals is not large, so even if they submit in a group, five hours is still enough to complete most of the scoring work.
"Professor Chang, good evening."
Harold took the initiative to step forward and say hello to Chang Haonan.
After some pleasantries, the former suddenly looked around, and then asked:
"Speaking of which...why didn't I see Professor Jameson today?"
As a relatively unknown person, Scholar, among all the special guests, he almost only knew the two people he met yesterday, so it was not surprising to ask about Jameson.
"Uh...he said he felt uncomfortable, so he wanted to go to bed early, so he didn't come to participate in the evening activities."
Chang Haonan barely suppressed his smile and said with regret Tone replied.
Of course, he didn't lie.
Because that's exactly what Professor Jameson said.
However, as the initiator of everything, Chang Haonan knew a little bit about the inside story——
The other party was not feeling well, and most likely he was angry and angry...
"Well... then tomorrow's conference is indeed more important."
Of course, Harold had no idea what was going on and just took it as what it was.
I was still thinking that it was no wonder that when I saw Professor Jameson the night before yesterday, he seemed abnormal.
While the guests were communicating with each other, Meng Weizheng, the head of the referee team on the other side, also stood up from the computer and strode to Chang Haonan:
"Report, all scoring work It’s done!”
As the translator conveyed this sentence, the originally noisy computer room suddenly became quiet.
"Professor Chang, it's getting late. I think... don't whet our appetites and announce the results as soon as possible."
Professor Suhas Patankar from the University of Minnesota said.
As a master of numerical calculations an era earlier than Anthony Jameson, Patankar can be said to be one of the original pioneers of the entire field.
Even now in 2002, his book "Numerical Calculation of Heat Transfer and Fluid Flow" is still the top textbook in the field of mass transfer dynamics.
It is natural that he should speak on behalf of the special guests.
Chang Haonan had no intention of betraying him at this time.
What's more, what's going to happen next is a masterstroke.
“Old Meng.”
He gestured to Meng Weizheng.
But a trace of hesitation flashed across the latter's face, and he whispered to Chang Haonan in Chinese:
"Mr. 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 full of vigilance.
I just don’t know how to look at the occasion.
Abnormal data?
Abnormal is normal, right?
If everything were to be normal, it would be abnormal...
"Do as I say!"
Chang Haonan said in a deep voice.
In this three-acre area of Torch Group, his prestige is still very effective.
Although Meng Weizheng was still a little worried, he still followed Chang Haonan's instructions and asked the staff to project the results of the game.
For a moment, everyone turned their heads and looked at the curtain on the side of the room.
The most eye-catching thing is naturally the first place.
"JingHang University...103.7 points!"
It must be said that the English names of some schools are purely for setting.
Just like Beijing Hang University.
If foreigners don't understand Chinese, they will have no idea what "JingHang" means.
If you understand...
Then there is no need for an English name.
Fortunately, because of Chang Haonan, JUAA's name is somewhat well-known in the academic world, so it won't really be a black eye.
So someone quickly recognized him.
"I have read the paper published by Professor Chang. This should be the school where he works."
"It is reasonable to rank first..."
"Indeed, if Chang is still Professor's students, then..."
"Probably not. I remember Professor Chang specifically said before that in order to avoid suspicion, his research group did not sign up for this competition."
" …”
In the discussion among everyone, the list on the curtain slowly slid down, and the subsequent rankings gradually appeared.
Second place, National Institute of Aeronautics and Astronautics.
Third place, MIT.
The scores of the two schools are exactly the same, both 100.2 points.
It’s just that the order of submissions differed by less than 10 minutes.
Basically the difference is just luck.
“ISAE...is it the one in France?”
Someone asked.
“Of course.”
The answerer was a French professor, with a smile in his tone.
Universities in continental Europe are generally not known for their comprehensive rankings, but that doesn't mean they don't have strength.
Fourth place, Samara State Aerospace University, 99.8 points.
Fifth place, Cranfield University, 99.4 points.
Sixth place, Bingcheng University of Technology, 98.9 points.
……
Except for a few Chinese names that occasionally flashed across the top of the rankings, they were basically all schools that had already enjoyed a great reputation in the world.
Therefore, everyone is not surprised.
Only when the school where someone teaches appears occasionally does the crowd burst into applause.
Twelfth place, Ohio State University, 85.4 points
“Oh...”
Suddenly seeing Professor Harold from his school, he subconsciously covered his mouth, but still let out a exclamation.
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 time.
Until….
“Wait!”
When the list scrolled down to No. 20, a voice suddenly sounded:
"So far, I don't seem to have seen Stanford University, which ranked first in the preliminary rounds, and Minnesota, which ranked third. City branch? "
One sentence is almost earth-shattering.
Meng Wei, who was not far away, also trembled when he heard these words -
This is what he just said about the abnormal results.
"I don't think I saw it either..."
"Indeed..."
"But this is already after the 20th place, with only 74.2 points...the top three in the preliminary round It’s impossible for the two schools to perform abnormally in the finals, right?”
The originally joyful atmosphere suddenly became a little subtle.
Since MIT ranks third, and there are two other universities from the United States in the top ten, it is absolutely impossible that the organizers are targeting the United States.
And with so many schools experiencing major decline in performance, it is obviously unlikely to be due to cheating in the preliminary exams.
However, who can be the special guests? Someone soon saw the clue:
“It seems... all the schools that used COMSOL to submit engineering documents in the preliminary round Didn’t you see it?”
Now, the mystery is undoubtedly solved.
More than a dozen sharp eyes suddenly looked at Chang Haonan.
Even Professor Harold was a little hesitant at this time.
"Professor Chang."
Finally, the highly respected Patankar stood up:
"I think there is an obvious abnormality in the final result." This means Obviously——
You are a business owner, take advantage of the host country, play a little side game, and promote your own products. Everyone can understand this and won't say anything.
But it would be too ugly to target a competitor like this without even acting.
For Chang Haonan, who has done the whole show, he naturally has to accompany them to continue the performance:
"I agree with Professor Patankar's opinion."
He He turned his hands away and glanced over the crowd without timidity:
"Therefore, it is recommended that a strict investigation be carried out!"
This dignified and righteous reaction was obviously beyond the expectations of others.
Even Patanka was a little confused. After being stunned for a while, he said:
"Then... when all the rankings are released, let's check which schools You shouldn’t have any objections to the result documents submitted by the school, right?”
Chang Haonanxin said that I have no objections, and I’m just waiting for your words.
check! Check it quickly!
I can’t let you out until the results are found...
Of course, on the surface, he still nodded with a serious look and replied in a decisive tone:
“Of course I have no objection.”
“We must find out why there is such a big difference in results between the preliminary round and the final!”
After such a small disturbance, 40 people finally came to the back of the curtain.
Starting from the 43rd place, the results column is not marked with numbers.
But N/A.
No valid results.
The two schools just discussed appear in this list.
"No results?"
This result was completely beyond the expectations of everyone except Chang Haonan.
What they originally thought was that the organizer would give a super low score to the participating groups using COMSOL.
But having no results is a bit outrageous.
Either it was not submitted at all, or there was a fatal problem in some crucial steps.
Otherwise, there will be some distinction between high and low.
At this moment, everyone was a little hesitant about the judgment just made.
Even if Chang Haonan really wants to cause trouble, he is not a fool.
How is it possible to use this method to see the problem at a glance?
For a while, the entire computer room fell into silence.
In the end, Chang Haonan, who really couldn't hold himself back, took the initiative to speak:
"Everyone, time is tight, let's start checking!"
After saying that, he didn't wait for anyone else to say anything. After reacting, he turned back to look at Meng Weizheng:
"Pick out the answer results submitted by all teams after the 43rd place!"
"Yes!"
Seeing that Chang Haonan was still able to issue instructions in an orderly manner at this time, the latter finally realized that his boss might have had a plan.
So this time without any hesitation, I opened the first project file directly as instructed.
However, in this case, COMSOL is not really used.
It is the software of Torch Group.
It only took less than 3 minutes for a group of big guys to see the problem——
I got the state of matter wrong at first, and then made a lot of stupid mistakes during the correction process. In the end, my mentality probably exploded, and I submitted an incomplete result one day ahead of schedule.
Because I submitted it early, I ranked first among N/A.
The next step is the second one.
It’s still Torch Group’s software...
This is a bit embarrassing.
The situation is similar to the first one. It was only half done and then handed over as a semi-finished product.
……
It wasn’t until the fourth one that I finally had a file with the extension .cmph.
After opening it, even the painting style is different from the previous ones.
The file content is very complete at first glance, and even tests several different modeling...
"How could this be..."
Someone subconsciously blurted out, wanting to say how could this be without results.
But halfway through the words, I got stuck in my throat.
Because everyone noticed.
Although the idea of solving the problem is very reasonable, the programming and calculation method selection are not too problematic.
But the most important thing is missing -
results.
Not only is there no final result.
There are not even intermediate results of testing the modeling.
The numerical calculation competition is not a college entrance examination, and there are no steps.
So there is no result, the grade is N/A, which is very reasonable.
"But why..."
Harold's brain was already a little burned:
"Why didn't they calculate the results?"
He has no doubt that with the quality of this answer, as long as he gets relatively accurate results, even if not all of them, he should be able to get a good ranking.
"Look at the back first."
Patanka waved his hand to stop Harold from continuing.
At this time, his eyes had gradually turned from suspicion to curiosity.
The last one is Stanford University, which everyone is most concerned about.
Program loading...
Everyone held their breath almost subconsciously.
After a minute that lasted 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 the content is more complete.
But again, no result.
The third, fourth, fifth...
Gradually, some people began to realize that something was wrong.
It is impossible for a submitted answer to be dropped.
So, if one or two calculations using COMSOL fail to produce results, they can still be regarded as accidental.
But all the answers submitted using COMSOL have no results, while others, Torch Group and ANSYS, everything is normal...
The problem obviously lies with the computing tools.
Professor Patankar, as a big boss who started studying mass transfer kinetics, did not talk nonsense and directly asked the staff to cut to the running log.
Even as a special guest, few people can directly analyze log files with the naked eye like Chang Haonan
But Patankar is indeed one of them.
He saw the essence directly through the phenomenon:
"That is to say...COMSOLM Multiphysics software, in the process of calculating the viscoelastic constitutive equation...at least the specific viscoelastic constitutive equation...there will be abnormal numerical oscillations, which will eventually cause the results to diverge!"
He Turning back, he looked at Chang Haonan.
Only this time, it was in a questioning and confirming tone.
If this is true, then the applicability of COMSOL in two-phase flow, and even in the entire chemical and energy fields, will be a big question mark.
At this time, Chang Haonan could no longer control his expression. He pinched his thigh a few times before he could 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 stage?"
To be fair, His acting skills are not very good.
But at this moment, everyone is still in the initial shock, so there hasn’t been any loopholes yet.
“And…”
Chang Haonan adjusted his mentality and continued to perform:
"And this kind of problem...can't it be solved by a constitutive equation that does not involve diffusion terms?"
"Is it difficult to use COMSOL? There...hasn’t done any research in this area?”
“?”
Everyone felt like something was wrong——
This is COMSOL’s technical roadmap. Why do you, the Torch Group, act like you know more about it than the real owner?
