Chapter 998 Something Seems 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 on a normal day, 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 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 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 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 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's a bit like "Thirty years to Hedong, thirty years to 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's 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 of a thief.

Most of the special guest reports have been planned internally.

However, including Chang Haonan, there are still several people whose topics have not 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 this aspect.

Naturally, it is impossible to leave a chance for Jameson.

"Oh, it uses 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 using 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 topic?"

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 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 problems 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 for accommodating 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.

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 people, so he consciously took on the logistics work of the whole team.

"On my way to buy lunch, I overheard a few people from other teams chatting."

George put a large plastic bag containing boxed 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."

"Ha...I knew it"

Lyles swallowed the sandwich in his mouth and sneered:

"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 to find 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:

"There'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 preparing to submit answers directly after completing the project documents without going back and redoing them..."

"This is only the first level..."

Lyles 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.”

"Calculating 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 he plan the work progress of his own team, he can even have a rough estimate of the situation of other participating teams.

As for whether this kind of estimation has actual 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 seriously considered it.

In any case, the situation of other groups is just a chore after all.

So after a brief chat during dinner, the two returned to work.

At this moment, Hermia, who had been motionless next to her, suddenly yawned:

"Ah~"

At the same time, he stretched his legs and slid the computer chair in front of the bag:

"Liles, I have started testing the results of the mixed element water domain here. There are a total of 8 preset elements, and the number of grids corresponding to each element is about 500,000 to RF model calculations."

As she spoke, she took out the milk and sandwiches from the bag, but instead of tearing open the packages immediately like George and Lyles, she stood up from the chair:

"It will probably be finished at six o'clock in the evening. I'm... 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 students of each other, and Stanford was not short of money, the three Lyles also chose to live here out of convenience.

The advantage 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 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.

Therefore, how to arrange rest time reasonably has become one of the abilities assessed in the finals.

Don't worry about whether it's reasonable or not, just say whether it's close to reality or not, right?

On the contrary, Zheng 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 was about half an hour left until the results of her calculations were calculated.

So she simply washed her face, and without bothering to do too many things, 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 your 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'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..."

Naturally, Hermia didn't know what happened yesterday, and thought it was Jameson who was addicted to work:

"Have a late break...are you also staying up late studying that question?"

"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, 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 computational complexity 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 it 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, his whole body was trembling.

"professor?"

She shouted in 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, his brain was not working well and he did not react.

But now, reviewing Chang Haonan's theme again, he suddenly realized something.

To solve a problem, the problem must first exist.

He certainly knew the grid-centered 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 the viscoelastic constitutive equation...

I am a little unfamiliar.

In other words.

When he designed the algorithm, he may have overlooked some very important details!

And then, a worse possibility emerged from Jameson's mind...

"Hermia."

Professor Jameson took several deep breaths in succession before he could barely stabilize his mentality:

"During your competition, have you ever encountered a solution process related to the viscoelastic constitutive equation?"

The voice was trembling when he spoke.

"Of course I have."

Hermia nodded almost without thinking:

"In fact... the step we are calculating right now is this."

"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 the whole person lost his balance...

Fortunately, the elevator space was small, Jameson did not fall directly to the ground, but leaned on the handrail on the side.

"Professor?"

Hermia, who found something wrong, hurried forward to help.

At this time, the elevator had also reached the first floor.

With a "ding--" sound, the elevator door opened.

"Don't worry about me... I'm fine..."

Jameson refused Hermia's help and signaled her to leave quickly:

"Go... take a look at your calculation results!"

"Quick!"
