Chapter 998 Something seems to be wrong
?Chang Haonan''s face still has some effect.
Therefore, in addition to Heltz and others who had made appointments in advance, most of the on-site guests also attended the dinner organized by him.
? And due to the rich variety of food and drink, as well as the frequent speeches and toasts given by representatives of different organizers, everyone was more or less drunk at the end.
Professor Anthony Jameson is no exception.
As a special guest, he was given more champagne than others.
It wasn’t until midnight that day that the dinner finally came to an end.
On the way back to the room, Jameson happened to meet Chang Haonan who was also about to leave.
“Oh…Professor Chang!”
??If the two of them met in normal times, they would probably just say hello in batches and then go their separate ways.
?But today, with the excitement of thinking he had succeeded in making a comeback and the drunkenness, he walked up directly and shook hands with the opponent very enthusiastically.
It was also at this time that Jameson suddenly noticed that there was another person standing next to Chang Haonan.
And judging from his appearance, he is not a staff member.
“I don’t know who this is...”
He looked at the other person up and down and confirmed that he didn''t recognize him.
I didn’t see this person at the dinner just now.
"oh…"
?Chang Haonan smiled and introduced Jameson:
“This is Professor Harold Huang from Ohio State University and a special guest of this conference. He missed the introduction session at the beginning of the dinner due to transportation reasons.”
Jameson hadn’t even heard of the other party’s name, but when he heard that the other party was also a special guest, he nodded to him for Chang Haonan’s sake.
?However, he completely ignored the other person’s extended hand, and did not notice Harold’s embarrassed expression due to being ignored.
Instead, he looked at Chang Haonan again—
In fact, Jameson''s heart was somewhat provocative at this time.
It means something like "thirty years to the east of the river, thirty years to the west of the river, don''t bully the old and the poor".
It feels like being suppressed by the Torch Group for so many years and finally turning around.
?Of course, he is a decent person after all.
The more you drink, the more you drink, and you won’t get so drunk that you lose consciousness.
Basic sanity can still be maintained.
??It''s impossible to do something as tasteless as making fun of someone.
Just suddenly mentioned the conference itself two days later:
"By the way, I forgot to ask at the dinner... I wonder what theme report you are going to give at the meeting?"
?This question is actually a bit silly.
?Most of the special guest reports have been planned internally.
However, including Chang Haonan, there are still several people whose subjects have not yet been made public.
So it’s normal to be asked.
But no matter what answer Chang Haonan gives, Jameson can always mention his own topic, then mention the new algorithm he developed, and then mention the results of COMSOL...
Thus pretending to be invisible.
?However, Chang Haonan is experienced in many battles in this regard.
It is naturally impossible to leave a chance for Jameson.
“Oh, it is to use the constitutive equation that does not involve diffusion terms to solve the problem of high computational weight involved in numerically solving the viscoelastic constitutive equation of the lattice-centered finite volume method..."
After finishing this somewhat awkward and lengthy title, he showed a meaningful smile:
“I wonder what Professor Jameson thinks of...this subject?”
?This answer made Jameson freeze on the spot for several seconds, as if he was ready to perform a set of combos, but was suddenly silenced.
Because the lattice-centered finite volume method... was the subject of his own report.
“Uh…not bad, not bad…”
Professor Jameson subconsciously felt that something was wrong, but at this time he was already a little dizzy, and his brain could not keep up with the speed at all.
?So I had to say a few casual words of support, and then said goodbye to Chang Haonan, preparing to go back to the room to have a good rest.
…
Time soon arrived at noon on the second day of the finals.
?In addition to the Stanford trio, other teams have also completed their analysis of the problem one after another and began to enter the problem-solving state.
? It has to be said that Lyles is extremely outstanding in both personal ability and leadership.
Under his command, by ten o''clock that night, Hermia had completed the modeling of several types of typical torsion elements—
Strictly speaking, the torsion element should be a set, not a stirring paddle, and it also includes a flow channel to accommodate two fluids, which is one of the most difficult points in this simulation.
??However, in the update to version 2.5, COMSOL has just enhanced its compatibility with the Solidwork modeling software, and has also solved to a certain extent the pain point of the Lagrangian method being difficult to apply to non-structural adaptive meshes.
Hence, it is almost a smooth journey.
??And Lyles himself has a more arduous task, so he is still burning the midnight oil in front of the computer.
Relatively speaking, George, who was only responsible for writing work, became the most leisurely among the three people, so he took on the logistics work of the whole team very consciously.
“I was just on my way to buy lunch when I overheard a few people from other teams chatting.”
George put a large plastic bag containing cartons of milk and sandwiches on the table, and said to Lyles while tearing open the package:
“As you guessed, a team has already encountered the physical state problem of substance B.”
“Heh...I knew it”
??Liles swallowed the sandwich in his mouth and let out a sneer:
“If you fail to notice the change in the state of matter at the beginning, it will take 12 to 15 hours at the fastest to complete the steps of discovering the problem. After troubleshooting, you will finally find the problem and then redo it..."
He turned his head and looked at the clock on the wall next to him:
“It’s definitely not enough time.”
Looking at the captain who showed a smile, George also nodded:
“Indeed, the mentality of the team I met has basically collapsed. They seem to be ready to submit answers directly after completing the project documents without going back and redoing them..."
“This is only the first level…”
??Liles threw the empty milk carton into the trash can:
"When designing the mixing device later, although the foaming screw was already provided in the question, the competition only provided a screw itself. An additional micro heat exchanger needs to be added between the metering section and the dispersing section to calculate the correct result. …Even I was almost fooled by this this morning.”
“Counting the time, there should be a second batch of participating teams that will soon be persuaded to withdraw by this heat exchanger...”
Obviously, on the other side of his calmness, he also has the extreme confidence of a top student from a prestigious school.
Not only can you plan the work progress of your own team, but you can also roughly estimate the situation of other participating teams.
??As for whether this kind of estimation has practical use, or is it just a means of showing off skills, or a manifestation of obsessive-compulsive disorder...
??I''m afraid Lyles himself hasn''t thought about it seriously.
In any case, the situation of other groups is just a chore.
So after a brief chat during the dinner break, the two returned to work.
At this moment, Hermia, who had been motionless next to her, suddenly yawned:
“Ah~” He stretched out his legs at the same time and slid the computer chair in front of the bag:
"Liles, I have started to test the results of the mixed element watershed here. There are a total of 8 preset elements. The number of grids corresponding to each element is about 500,000 to 600,000. The MRF type model is used calculate."
??As she spoke, she took out the milk and sandwiches from the bag, but she did not immediately tear open the packaging like George and Lyles did, but stood up from the chair:
“It will probably be finished at six o’clock in the evening. I’ve been... uh... not feeling very well these days. I’ll go up and have a rest first, and then I’ll come back down..."
As a special guest of the conference, Professor Anthony Jameson was naturally accommodated in a suite upstairs at the conference venue.
As the three Lyles students were students of each other, and Stanford was not short of money, they also chose to live here out of convenience.
The good thing is that you can just take the elevator upstairs and go back to your room to sleep.
??It''s definitely better than lying down and resting in the computer room cubicle.
"no problem."
?Liles said without looking back.
Although the competition time is set to last for 48 consecutive hours, it is impossible for normal people to maintain continuous high-intensity work for such a long period of time, let alone coffee or even drugs.
Hence, the three participating team members must take turns to rest between work breaks.
Hence, how to arrange rest time reasonably has become one of the abilities tested in the finals.
Don’t worry about whether it’s reasonable or not, just say whether it’s close to reality or not, right?
?Hong Haonan’s principle is basically that if you participate in my competition, you can still get a ranking.
Basically, after graduation, you can seamlessly join a large factory to lead projects.
…
A few hours later, Hermia awoke from her sleep.
Looking at the time, it was already around 5:30 pm.
There is about half an hour left before her calculation results are calculated.
?So she simply washed her face, and without bothering to do too much, she prepared to go to the computer room to complete the last part of the entire design—
Export the calculation results, and then optimize again based on the results.
If nothing unexpected happens, then this round of optimization is over and you can submit the answer directly.
In the elevator, she coincidentally met Jameson who was also about to go downstairs.
“Professor, afternoon…”
?Hermia was about to say hello when she noticed that the other person''s face was a little haggard:
“Did you… just wake up?”
Jameson rubbed his still swollen temples and shook his head:
“That’s not true, it’s just that I drank a little too much yesterday and rested late, so I have a bit of a headache…”
?Hermia naturally didn’t know what happened yesterday, and thought it was Jameson who was addicted to work:
“Have a late rest...Are you also staying up late studying that topic?”
“Ah...no.”
Jameson shook his head in embarrassment, but he was also embarrassed to admit that he drank a little too much at the dinner, so he avoided the important and ignored the important:
“Yesterday, I talked with the organizer, Professor Chang Haonan, about his conference report, about... about...”
He spent a few seconds and finally remembered the content of his latest chat with Chang Haonan:
“It is about high computational efficiency in numerically solving viscoelastic constitutive equations…”
At this point, Jameson''s voice stopped abruptly.
The movements of his hands also stopped.
“Calculate what…”
?Hermia only heard half of the words and then stopped talking. She turned around subconsciously.
??But he saw Jameson''s face was pale, with an extremely horrified expression on his face.
Moreover, the whole body was trembling.
"professor?"
She shouted with concern.
But the other party seemed not to hear.
In just a few seconds, Jameson’s forehead was already covered with fine sweat—
Last night, my brain was not in a good state and I couldn’t react.
But now looking back at Chang Haonan’s theme, he suddenly realized something.
To solve a problem, you must first have a problem.
He certainly knows the lattice-centred finite volume method.
Or rather, the core of the entire COMSOL 2.5 update is this technology.
but…
??Problems with high computational weight in numerically solving viscoelastic constitutive equations…
?But it’s a little strange.
in other words.
When he designed the algorithm, he probably overlooked some very important details!
And then, an even worse possibility emerged from Jameson''s mind...
“Hermia.”
Professor Jameson took several deep breaths in succession before he managed to stabilize his mentality:
“During the competition, have you ever encountered the solution process related to the viscoelastic constitutive equation?”
Her voice trembled when she spoke.
“Of course I have.”
?Hermia nodded almost without thinking:
“Actually...the step we are calculating right now is this.”
∣
?Hermia''s answer was like a thunderbolt, exploding directly in Jameson''s ears.
Immediately afterwards, the latter felt that his vision went dark and he lost his balance...
Fortunately, the elevator space was small, so Jameson did not fall directly to the ground, but leaned on the side handrail.
"professor?"
?Hermia, realizing something was wrong, quickly stepped forward to help.
?At this time, the elevator has also reached the first floor.
?With a "ding-" sound, the elevator door opened.
“Leave me alone...I’m fine...”
Jameson refused Hermia’s support and motioned for her to leave quickly:
“Go quickly... and take a look at your calculation results!”
"quick!"
