Chapter 997: A big fight!

Like Professor Jameson on the stage, most of the people in the audience only experienced a brief moment of confusion after seeing the question, and then quickly realized the essence of the problem.

"Should it be a two-phase flow problem of non-Newtonian fluid?"

George asked in a low voice to his two companions.

"Yes."

Lyles nodded, and then showed a playful expression:

"And there's a trap hidden in the conditions of this question..."

The other two were stunned when they heard this and looked at the conditions on the big screen again.

It was Hermia who first responded:

"Gas-liquid two-phase flow?"

According to the process conditions given in the question, substance B will be in gaseous rather than liquid state for about two-thirds of the process.

"oh..."

George next to him also smiled knowingly:

"It seems that the tournament is trying to use these details to cause trouble for us..."

“Although it’s an inconspicuous place, I’m afraid many people will be cheated.”

Lyles crossed his legs:

"The person who set this question is really bad..."

In his opinion, this should be a trick used by the Torch Group against them.

The Chinese team could completely avoid it with just a little hint.

If other teams don’t pay attention, it will affect the results.

To some extent, it is also a reasonable use of the host advantage.

In fact, in numerical calculation software, there is a database for most common fluids.

If the calculation conditions you enter are too outrageous, such as liquid water at 1 bar and 1000c, there will definitely be a prompt.

But today these two polymer melts are clearly not considered “common”.

Although the problem will be discovered in the end, the 48-hour competition time is not sufficient to begin with, and if it is delayed further, it is very likely that the problem cannot be completely solved.

If we consider the mental impact of this incident, the potential loss will be even greater.

This kind of behavior of setting traps in questions is quite common in ordinary exams.

However, competitions, especially high-level competitions, are rarely encountered.

Because it is generally not the focus of inspection.

At this time, Hertz next to him also came over:

"Two-phase flow problems are probably the most classic CFD application areas. Although COMSOL's advantage in this area is not as great as that in homogeneous turbulence problems, according to our previous tests, its computational efficiency is obviously stronger than that of competing products from Torch Group and ANSYS."

"The rest of the matter depends entirely on you..."

Although nearly 10 teams that reached an agreement with COMSOL entered the finals, there is no doubt that these three players from Stanford University, who were personally coached by Professor Jameson, are their seeded team.

It was also the team that received the most attention before the finals.

After the preliminary round, Hertz's ambitions have expanded a lot.

He even began to consider whether it was possible for Lyles and his two teammates to continue their form in the final and take first place again.

By then, getting first place in both the preliminary and final rounds will be perfect publicity material.

"Do not worry."

Lyles replied:

"They set up a few traps in the questions, but they are not hard to see through."

If he was still a little uncertain before seeing the question, now his mentality has basically stabilized.

People are like this sometimes.

If the whole process goes completely smoothly, people will become suspicious.

But if there are a few small obstacles that don't even play a role, you will feel much more at ease.

However, this part cannot actually be considered as Chang Haonan’s plan.

In fact, whether the substance is in gas or liquid state has no effect on his plan.

It’s just that polymer melts are not very common, and those that can be used for injection molding are even fewer, so after careful selection, there are only a few options left for making questions.

Other groups are even more abstract.

As for the fact that the opponent's vigilance was lowered by accident...

It can only be said that it was an unintentional act.

……

After the exam questions were announced, the more than 200 contestants naturally left the conference hall immediately and went to their respective examination rooms to start answering questions.

Judging from their expressions, most of them are eager to try.

After all, the team that can make it to the finals cannot be a group of casual players.

Everyone can basically see that the difficulty of this question is basically at the limit of their ability.

Just a little jump and you can get there.

And if you can have an epiphany while answering questions, it may even improve your ability further...

The rest of the people in the conference room started chatting in a relatively relaxed manner.

At this point in time, almost everyone felt that they had gotten a great deal.

Not to mention scholars and professors, competitions and conferences will have a huge positive impact on the visibility of the entire industry. In the future, the difficulty of applying for projects or commercial cooperation will be greatly reduced.

The sponsors, especially those in the chemical industry, were also ecstatic after seeing topics that were so close to actual production.

This means that numerical computing techniques have at least the potential to reduce their costs in the design and production processes.

As for the three companies that mainly provide numerical computing services and tools...

COMSOL feels that it has a huge advantage and wins.

ANSYS specializes in this type of process production problems, and even provides preset models of various chemical equipment in the software. Although the performance is slightly worse, it is lightweight enough and can also be used to win.

Not to mention Torch Group, Chang Haonan is already ready to enjoy the scene when the results come out...

"Dear guests, please stay."

Chang Haonan simply packed up his things, then stood up from his seat and said half-jokingly:

"Don't worry, we don't have to take the same exam as the contestants..."

This one sentence caused a good-natured laugh from the audience.

After briefly livening up the atmosphere, he continued:

"The organizing committee of the conference has arranged a welcome banquet tonight. Please be sure to attend it then..."

If we let these people go back now, they will definitely study the problem simultaneously with the players.

Although Chang Haonan was confident that the pit he had dug was very covert, those sitting here were all well-known figures in the field of numerical computing.

If someone notices something and finds a chance to alert everyone in the venue, it would be troublesome.

So, at least they have to be locked in the ballroom tonight.

As for tomorrow...

Tomorrow it will be too late to do anything...

……

At the same time, the participating students have already sat in front of their computers and started to study the previous question carefully.

The Stanford University trio almost skipped this step.

Lyles's ability is indeed extraordinary. Just now in the corridor, he had almost prepared a draft in his mind.

Now sitting in front of the computer, after a brief review, he started giving instructions directly:

"In the first stage, Hermi was responsible for establishing the physical property models of substances A and B in different states, and I was responsible for the geometric model and meshing."

"In the second stage, I was responsible for the simulation calculation conditions and the setting of fluid physical parameters and boundary conditions. Hermi was responsible for the modeling of the molding screw and barrel. At the same time, we prepared several typical torsion components... actually the models of the stirring paddle, so that we can test them later."

"In the third stage, based on the test results of the impeller models with different characteristics, we select the best one and optimize it based on it..."

"..."

Under his command, Hermia quickly sorted out her thoughts and began to deal with the first task in an orderly manner.

"and many more……"

George next to him was stunned for a moment:

"I...what about me?"

Lyles glanced at him:

"There's nothing you're good at with this problem. You'll be responsible for handling the paperwork while we move forward."

"When the final results come out, I want to see your calculation documentation in sync with the engineering files!"

After saying all this in one breath, Lyles turned his attention back to the screen in front of him and took a deep breath.

Next, he's going to do something big!
