Chapter 998 Something seems wrong
Chang Haonan's face still has some effect.
Therefore, except for Hertz and others who had made appointments in advance, most of the guests on site also attended the dinner he organized.
And because of the rich variety of food and drinks, and the frequent speeches and toasts from representatives of different organizers, everyone was more or less drunk by the end.
Professor Anthony Jameson is no exception.
As a special guest, he was given more champagne than others.
The dinner finally came to an end late in the night.
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 met under normal circumstances, they would probably just say hello and then go their separate ways.
But today, taking advantage of his excitement over his successful comeback and the alcohol, he walked straight up to the other person and shook hands with him 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 attire, he is not a staff member.
"I don't know who this is..."
He looked the other person up and down and confirmed that he didn't know him.
I didn't see this kind of person at the dinner just now.
"Oh……"
Chang Haonan smiled and introduced to Jameson:
"This is Professor Harold Huang from Ohio State University. He is also a special guest of this conference. He missed the introduction session at the beginning of the dinner due to traffic reasons."
Jameson had never even heard of the other party's name, but when he heard that the other party was also a special guest, he nodded to the other party for Chang Haonan's sake.
However, he completely ignored the other person's outstretched hand, nor did he notice Harold's somewhat embarrassed expression due to being ignored.
Instead, he looked at Chang Haonan again——
In fact, Jameson was feeling somewhat provocative at this moment.
It's a bit like "Don't be fooled by your old age and poverty"
It's like being suppressed by Torch Group for so many years and finally turning the tables.
Of course, he was a decent man after all.
Even though he drank a lot, he was not completely drunk and unconscious.
Basic sanity can still be maintained.
It's impossible to do something so tasteless as jumping in someone's face and taunting them.
Just suddenly mentioned the conference itself two days later:
"Oh, by the way, I forgot to ask you at the dinner just now... I wonder what topic you are going to report on at the meeting?"
This question is actually a bit tricky.
Most of the special guests’ reports have already been decided internally.
But the themes of several people, including Chang Haonan, have not yet been made public.
So it’s normal to be asked.
But no matter what answer Chang Haonan gave, Jameson could always turn to his own topic, then mention the new algorithm he developed, and then mention the COMSOL results...
Thus pretending to be invisible.
However, Chang Haonan is also experienced in this regard.
Naturally, there is no way to leave any chance for Jameson.
"Oh, it is to use the constitutive equation that does not involve diffusion terms to solve the high computational weight problem when the grid-centered finite volume method involves numerically solving the viscoelastic constitutive equation..."
After finishing this somewhat awkward and lengthy title, he smiled meaningfully:
"I wonder what Professor Jameson thinks of... this topic?"
This answer made Jameson stand there in a daze for several seconds, as if he was ready to launch a combo but was suddenly silenced.
Because the grid-centered finite volume method... was exactly the topic of his own report.
"Uh... not bad, not bad..."
Professor Jameson subconsciously felt that something seemed to be wrong, but at this time he was already a little dizzy, and his brain could not keep up with the state.
So he just said a few words in response, then said goodbye to Chang Haonan and prepared to go back to his room to have a good rest.
……
Time soon passed and it was noon on the second day of the finals.
In addition to the Stanford trio, other teams also completed their analysis of the questions and began to solve them.
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 typical torsion components.
Strictly speaking, the torsion element should be a group rather than a single agitator, and it also includes a flow channel that contains two fluids, which is one of the most difficult points in this simulation.
However, in the update of version 2.5, COMSOL has enhanced its compatibility with Solidwork modeling software, and to a certain extent solved the pain point that the Lagrangian method is difficult to apply to unstructured adaptive grids.
So it was almost smooth sailing.
Lyles himself has a heavier workload, so he is still working late into the night in front of his computer.
Relatively speaking, George, who was only responsible for writing work, became the least busy among the three, so he very consciously took on the logistics work of the entire team.
"I was on my way to buy lunch just now, and I overheard a few people from other teams chatting."
George put a large plastic bag of milk and sandwiches on the table and said to Lyles while he was tearing open the package:
"Just as you guessed, a team has already encountered the problem of the physical state of substance B."
"Oh... I knew it."
Lyles swallowed the sandwich in his mouth and sneered:
"If you don't notice the change in physical state at the beginning, it will take at least 12 to 15 hours to find the problem, then go through the troubleshooting process, 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 too late."
Seeing the captain smiling, George nodded as well:
"Indeed, the team I met had basically lost their minds. They seemed to be prepared not to go back and redo the work. They just submitted the answer after finishing the engineering documents..."
"This is just the first level..."
Lyles throws the empty milk carton into the trash:
"When I was designing the stirring device later, although the foaming screw was provided in the question, the competition only provided a screw itself. It was necessary to add an additional micro heat exchanger between the metering section and the dispersion section to calculate the correct result... Even I was almost tricked by this this morning."
"According to the time, the second batch of participating teams should be discouraged by this heat exchanger soon..."
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 he plan the work progress of his own team, but he can also have a rough estimate of the situation of other participating teams.
As for whether this estimate is actually useful, or is it just a means of showing off, or a manifestation of obsessive-compulsive disorder...
I'm afraid Lyles himself hasn't thought about it seriously.
In any case, the situations in the other groups were just trivial matters after all.
So after a brief chat during dinner, the two returned to work.
At this moment, Hermia, who had been silent, suddenly yawned:
"Ah~"
At the same time, he stretched out his feet and slid the computer chair in front of the bag:
"Lyles, I have already started to test the results of the mixed element watershed. There are a total of 8 preset elements. The number of grids corresponding to each element is about 50 to 60. The MRF model is used for calculation."
As she spoke, she took out the milk and sandwiches from the bag, but instead of tearing open the packaging immediately like George and Lyles did, she stood up from her chair:
"It will probably be finished by six in the evening. I haven't been feeling well these past few days... uh... I'll go upstairs to rest for a while and come down later..."
As a special guest of the conference, Professor Anthony Jameson was naturally arranged to stay in a suite upstairs in the conference venue.
As Lyles and the other two were students of the other school, and Stanford was not short of money, they also chose to live here for 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."
Lyles said without turning his head.
Although the competition time is set to 48 consecutive hours, it is impossible for a normal person to maintain such a long period of continuous high-intensity work, let alone relying on coffee, even if they rely on drugs.
Therefore, the three participating team members must take turns to rest between work.
Therefore, how to arrange rest time reasonably has become one of the abilities tested in the finals.
Don’t worry about whether it is reasonable or not, just ask whether it is close to reality?
The basic principle of Anti-Normal Haonan is that if you participate in my competition, you can still get a ranking.
Basically, after graduation, you can seamlessly enter a large company to lead projects.
……
A few hours later, Hermia woke up from her sleep again.
Looking at the time, it was already around 5:30 in the afternoon.
There was still about half an hour left before she could come up with the result.
So she simply washed her face, not caring about dressing up too much, and prepared to go to the computer room to complete the last part of the entire design work -
Export the calculation results and then optimize again based on the results.
If nothing unexpected happens, 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, this afternoon..."
Hermia was about to say hello when she noticed that the other person looked a little haggard:
"You just woke up?"
Jameson rubbed his still swollen temples and shook his head:
"That's not the case. I just drank too much yesterday and went to bed late, so I have a headache..."
Hermia naturally had no idea what happened yesterday, and thought Jameson was obsessed with work:
"Rest late...Are you also staying up late to study that question?"
"Ah... no."
Jameson shook his head awkwardly, but he was too embarrassed to admit that he drank a little too much at the dinner party, so he avoided the main point:
"Yesterday I talked to the organizer, Professor Chang Haonan, about his conference report, which was about... about..."
It took him a few seconds to finally remember the content of his latest chat with Chang Haonan:
"It is about the high computational cost of 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 what was said and turned away subconsciously.
But I saw Jameson was pale and had an extremely horrified expression on his face.
Moreover, the whole body was shaking.
"professor?"
She called out in concern.
But the other party acted as if he didn't hear it.
In just a few seconds, Jameson's forehead was already covered with sweat.
My brain wasn't working very well last night so I didn't react.
But now looking back at Chang Haonan's topic, he suddenly realized something.
To solve a problem, the problem must first exist.
Of course he knew the Gexin finite volume method.
Or rather, the core of the entire COMSOL 2.5 version update is this technology.
but……
The problem of high computational weight when numerically solving viscoelastic constitutive equations…
But it feels 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 before he managed to calm down:
"During your competition, have you ever encountered a solution process related to the viscoelastic constitutive equation?"
His voice was trembling when he spoke.
"Of course I have."
Hermia nodded almost without thinking:
"Actually... this is the step we are calculating right now."
"Boom——"
Hermia's answer was like a thunderbolt, exploding directly in Jameson's ears.
Then, the latter felt a black screen in front of his eyes, and he lost his balance...
Fortunately, the elevator was small, so Jameson did not fall directly to the ground, but leaned on the handrail on the side.
"professor?"
Hermia, realizing something was wrong, rushed forward to help.
At this time, the elevator had reached the first floor.
With a "ding" sound, the elevator door opened.
"Don't mind me... I'm fine..."
Jameson refused Hermia's offer of support and motioned for her to leave:
"Go and take a look at your calculation results!"
"quick!"
