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, and 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 the 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 to Jameson:
"This is Professor Harold Huang, Ohio State University He is also a special guest of this conference. He missed the introduction at the beginning of the dinner due to transportation reasons.”
Jameson had not even heard of the other party’s name, but he heard that the other party was also a special guest. , but for the sake of Chang Haonan, he nodded to the other party.
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 kind of means "thirty years to the east of Hedong, thirty years to the west of Hexi, don't bully the old and poor".
It feels like being suppressed by the Torch Group for so many years and finally turning around.
Of course, he is a decent guy after all.
The more you drink, the more you drink, and you won’t reach the state of being completely drunk and confused.
Basic sanity can still be maintained.
It is impossible to do something so tasteless as making fun of someone.
I 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.
But there are several people, including Chang Haonan, whose themes 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 cool. Invisibly.
However, Chang Haonan is experienced in this aspect.
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 with the lattice-centered finite volume method...”
After finishing this slightly awkward and lengthy title, he showed a meaningful smile:
"I wonder what Professor Jameson thinks... of this topic?"
This The 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... is exactly 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, torsion The components 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 to a certain extent has also solved the problem of the difficulty of applying the Lagrangian method to non-structural adaptive networks. The pain points in the grid.
So, it’s almost a smooth ride.
Lyles himself has a more arduous task, so he still burns midnight oil in front of the computer.
Relatively speaking, George, who was only responsible for writing work, became the most leisurely among the three, so he consciously took on the logistics work of the whole team.
“I just happened to overhear a few people from other teams chatting on my way to buy lunch.”
George put a large plastic bag containing cartons of milk and sandwiches on the On the table, while tearing open the package, he said to Lyles:
"As you guessed, a team has already encountered the problem of the physical state of substance B."
"Ha... I knew it"
Lyles 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, then the fastest It also takes 12 to 15 hours to go through the steps of discovering the problem, and then after troubleshooting, finally find the problem, and then redo it..."
He turned his head and looked at the wall clock on the wall next to him:
“There is 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 preparing to redo the project without going back. Submit the answers directly after completing the documents..."
"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 is already provided in the question, the competition only provides a screw itself. It is necessary to add an additional micro heat exchanger between the metering section and the dispersing section to calculate the correct As a 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 have a rough estimate of the situation of other participating teams.
As for whether this estimate has practical use, or is it just a means of showing off skills, or a manifestation of obsessive-compulsive disorder...
I am afraid Lyles himself has not seriously considered it. .
In any case, the situation of other groups is just a chore after all.
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~" At the same time, she stretched her legs and slid the computer chair in front of the bag: < br>
"Liles, I have started testing 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. Use is the MRF type model calculation. ”
As she spoke, she took out the milk and sandwiches from the bag, but she did not tear open the package immediately like George and Lyles did, but stood up from the chair:
"Probably. It will be finished at six o'clock in the evening. I have been... um... not feeling very well these days. I will go up and have a rest first, and then come back down..."
Professor Anthony Jameson served as a special guest at the conference , was naturally arranged to stay in a suite upstairs at the venue.
The three Lyles were students of each other, and Stanford was not short of money, so 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.
Therefore, the three participating team members must take turns to rest between work.
So, 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 say whether it is close to reality or not, right?
Abnormal 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 woke up again from her sleep.
Looking at the time, it’s already around five-thirty in the afternoon.
There is about half an hour left until the results of her calculations are calculated.
So she simply washed her face, and without worrying about doing too much, she was ready 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 your answer directly.
In the elevator, she coincidentally met Jameson who was also about to go downstairs.
"Professor, afternoon..."
Hermia was just about to say hello when she noticed that the other person's face was a little haggard:
"You... just woke up?"
Jameson rubbed his still swollen temples and shook his head:
"That's not true, I just drank a little too much yesterday. , I rested late and have a bit of a headache..."
Of course Hermia didn't know what happened yesterday, and thought it was Jameson who was addicted to work:
"I rested late...you too Are you staying up late studying that topic? ”
"Ah... no."
Jameson shook his head in embarrassment, but he was too embarrassed to admit that he drank a little too much at the dinner, so he avoided the important and ignored the easy:
"I talked to the organizer yesterday Professor Fang Chang Haonan talked 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's about the high computational efficiency in numerically solving viscoelastic constitutive equations..."
At this point, Jameson's voice stopped abruptly.
The movements of his hands also stopped.
"Calculating what..."
Hermia only heard half of it and stopped talking, turning around subconsciously.
But Jameson looked pale and had a horrified expression on his face.
Moreover, his 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——
My brain was not very good last night 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.
Of course he knows the finite volume method at the center of the grid.
Or rather, the core of the entire COMSOL 2.5 update is this technology.
But...
The problem of high computational weight in numerically solving viscoelastic constitutive equations...
is a bit unfamiliar.
In other words.
When he designed the algorithm, he probably ignored some very important details!
And then, an even worse possibility emerged from Jameson's mind...
"Hermia."
Professor Jameson took several deep breaths in succession , and then managed to calm down:
"During the competition, have you ever encountered the solution process related to the viscoelastic constitutive equation?"
My voice was trembling when I spoke.
"Of course I have."
Hermia nodded almost without thinking:
"Actually... the step we are calculating now is this."
" Boom——"
Hermia's answer was like a thunderbolt, exploding directly in Jameson's ears.
Immediately afterwards, the latter felt his vision go 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 handrail on the side.
“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 signaled her to leave quickly:
"Go quickly... Take a look at your calculations! ”
“Quick! ”
