Chapter 1000: Torch Group, Eternal God (10,000 per day, please give me a monthly vote)
March 29, 8 pm.
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, checking the final scores with Chang Haonan—
According to the rules of the competition, the final scores of the finals need to be witnessed by a group of specially invited guests and subject to random inspection.
After confirmation, the awards will be announced and awarded at the conference the next day.
Different from 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 go back to work somewhere, you basically 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 that number of early submissions...
After inspection, it was found that it was basically due to a breakdown in 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 said hello to Chang Haonan.
After some pleasantries, the former suddenly looked around and asked:
“Speaking of which...why didn’t you see Professor Jameson today?”
As a relatively unknown 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 didn''t feel well, 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 replied with a regretful tone.
?Of course, he didn''t lie.
Because that’s exactly what Professor Jameson said.
It’s just that, as the initiator of everything, Chang Haonan knew a little bit about the inside story—
?The other person is not feeling well, and most likely he is feeling anxious and angry...
“Well…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 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... 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 one of the top textbooks in the field of mass transfer dynamics.
It is natural that he should speak on behalf of the special guest.
?Chang Haonan had no intention of betraying him at this time.
What''s more, what''s going to happen next is a masterstroke.
“Lao 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...that someone is deliberately causing trouble..."
I have to say that Meng Wei is really full of vigilance.
It’s just that I don’t know how to judge the occasion.
?Data anomalies?
Abnormal is normal, right?
If everything was normal, it would be abnormal...
“Do as I say!”
Chang Haonan said in a deep voice.
In this small area of ????the Torch Group, his prestige is still very effective.
Even though 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.
“JingHangUniversity…103.7 points!”
It must be said that the English names of some schools are purely for setting.
Just like Beijing Hang University.
Foreigners who don’t understand Chinese 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 discredited.
?So someone quickly recognized him.
“I have read the papers published by Professor Chang. This should be the school where he works.”
“Then ranking first is reasonable…”
“Indeed, if you are still a student of Professor Chang, 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 midst of the discussion, the list on the curtain slowly slid downwards, 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 submission differs by less than 10 minutes.
The difference is basically just luck.
“ISAE...is it the one in France?”
Someone asked.
“Of course.”
The answerer is a French professor, with a smile in his tone.
Universities in continental Europe are generally not known for their comprehensive rankings, but this does not mean that they lack 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.
…
The top ones, except for a few Chinese names that occasionally flashed by, are basically schools that have already enjoyed a great reputation in the world.
?Hence, everyone is not surprised.
?Only occasionally does the crowd burst into applause when the school where a particular person teaches appears.
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….
"etc!"
When the list scrolled down to the 20th place, a voice suddenly sounded:
“So far, I haven’t seen Stanford University, which ranked first in the preliminary round, and Minnesota Twin Cities, which ranked third?”
One sentence is almost earth-shattering.
? Meng Wei, who was not far away, also trembled when he heard these words -
That''s what he just said about the abnormal results.
“I don’t think I saw it either…”
"really…"
"But this is already behind the 20th place, with only 74.2 points... The two schools ranked in the top three in the preliminary round cannot perform abnormally together 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 so many schools have experienced significant decline in performance, and it is obviously unlikely to be due to cheating in the preliminary examination.
?However, it didn’t take long for someone to figure out who could be the special guest:
“It seems...none of the schools that used COMSOL to submit engineering documents in the preliminary rounds were seen?”
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 Patanka stood up:
“I think there are obvious abnormalities in the results of the final.” ????The meaning is obvious—
You are a business owner, so you can 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 a bit ugly to target competitors without even showing off.
As for Chang Haonan, it is natural to accompany them to continue the performance:
“I agree with Professor Patankar.”
He turned away his hands and glanced at the crowd without timidity:
“So, it is recommended to conduct a strict investigation!”
?This reaction with a dignified face and awe-inspiring righteousness 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 the result documents submitted by those schools. You should have no objections, right?"
?Chang Hao Nanxin said that I have no objection, I am 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 figure out why there is such a big difference in results between the preliminary rounds and the finals!”
?After such a small disturbance, 40 people finally came to the back of the curtain.
From the 43rd place onwards, the results column is not marked with numbers.
but N/A.
There are 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 organizers would give a super low score to the participating groups using COMSOL.
But it would be a bit outrageous to have no results.
Either it was not submitted at all, or there were fatal problems in some crucial steps.
Otherwise, there will be points for high and low.
?At this time, 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 that can identify the problem at a glance?
For a time, 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 finishing speaking, without waiting for anyone else to react, he turned back to look at Meng Weizheng:
“Select the answer results submitted by all teams after the 43rd place!”
"yes!"
The latter saw that Chang Haonan could still issue instructions in an orderly manner at this time, and finally realized that his boss might have had a plan.
?So this time without any hesitation, I opened the first project document directly as instructed.
??However, in this case, it’s really not COMSOL.
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 the beginning, and then made a lot of stupid mistakes during the correction process. In the end, I probably had an explosive mentality and submitted an incomplete result one day ahead of schedule.
Because I submitted it early, I ranked first among N/A.
Following this, is the second copy.
It is still the software of Torch Group...
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 a .cmph extension.
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...”
Some people blurted out subconsciously, wondering how it was possible that there was no achievement.
But halfway through the words, I got stuck in my throat.
Because everyone noticed.
Although the idea of ????dealing with the problem is very reasonable, the programming and calculation method selection are not too problematic.
But the most important thing is missing—
result.
It’s not just that there is no end result.
There are not even results from intermediate tests of the modeling.
??The numerical calculation competition is not a college entrance examination, and there are no steps.
So there is no result and the grade is N/A, which is very reasonable.
“But why…”
Harold’s brain is already a little burned:
“Why don’t they figure out 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 the submitted answers to be dropped.
Hence, 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 in Torch Group and ANSYS are doing fine...
?The problem obviously lies in the computing tools.
Professor Patankar, as a big boss who started studying mass transfer dynamics, did not talk nonsense and directly asked the staff to cut to the running log.
Even special guests, few people can directly analyze log files with naked eyes like Chang Haonan.
But Patankar is indeed one of them.
He saw the essence directly through the phenomenon:
"That is to say...COMSOLMultiphysics 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 lead to divergence of the results!"
He turned back and looked at Chang Haonan.
Only this time, it was in a questioning and confirming tone.
??If this is the case, 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 barely holding 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, right?”
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 with a constitutive equation that does not involve diffusion terms?”
"Is it possible that COMSOL...hasn''t done any research in this area?"
?)
?)
?Everyone felt like something was wrong—
?This is the technical roadmap of COMSOL. Why do you, the Torch Group, act like you know more about it than the real owner?
