Chapter 994 Final Preparation (New January, Please Give Me Monthly Votes)

Chapter 994 Final Preparation (A new January, please vote for me~)

In Hilts' original idea, although the competition topic was very favorable to his team, after all, from referees to organizers, to co-organizers and witnesses, all units were from Torch Group. What could you do to compete with them?

Especially in such a competition with an extremely complicated scoring method.

Any modification in any detail would be enough to change the entire result.

They have done this kind of thing before.

They have a lot of experience.

Therefore, Hilts' best expectation at the beginning was that there would be about a dozen teams using COMSOL software to represent their schools or research institutions in the finals -

As long as they can put up their own banner in the competition held by the opponent, they will win.

However, the final result gave him a big surprise.

Two of the top three teams are his own.

Four of the top ten teams are his own.

As for the rest...

Sorry, the overall ranking is presented in the form of ten groups per page.

In other words, most people will only pay attention to the first page and the page with their own team.

This is no longer just a flag.

This is a flag planted in the opponent's base camp.

Although it can be seen that the majority of contestants choose to use TORCH Multiphysics, COMSOL has achieved a balance in the high-end game with a relatively small sample size.

To some extent, it can even be said to be an advantage.

On the contrary, it further demonstrates its excellent performance in the field of CFD.

Including the group of Santa Clara University next door, although the results are slightly worse and to a considerable extent they are cramming, the overall ranking still reached 31st.

It also entered the finals on behalf of the school without any suspense.

And not only that.

The rules of the competition do not impose too many restrictions on the calculation methods and calculation tools of the participating teams.

There are still about three weeks to the finals.

This means that there may be teams that decide to change the calculation software temporarily after seeing the results of the preliminary round.

Or at least make more preparations.

So by the time of the finals, the number of teams in the COMSOL camp is likely to increase further...

Even... occupy the mainstream!

Thinking of this, Hertz seemed to have seen the day when he would get promoted and get a raise, and reach the pinnacle of his life, with his fists hitting the torch and his feet stepping on ANSYS.

"I think we can celebrate."

Although he was trying to restrain himself, his voice still trembled a little.

Even Professor Harold, who was always serious, did not refuse this time for the first time.

Instead, the three students showed amazing calmness.

"I think the current focus is still to prepare for the finals."

Lyles Connor clenched his fists, obviously still not over the excitement just now, but still tried to show a calm look:

"A high ranking in the preliminary round will actually bring more pressure to the finals."

"Moreover, this result is largely due to the problem. We can't expect us to have such good luck in the finals, so we still need to increase training for special types of problems during this period, such as the particle flow problem like the first question in the preliminary round. If we encounter it in the finals, there is no chance to choose two out of three..."

"There is also the problem of combining computational fluid dynamics and computational structural mechanics, which is also a shortcoming in our previous training. Although it is impossible to involve it in the difficulty of the preliminary round, it is completely uncertain in the final..."

"..."

Connor's rationality also obviously affected his teammates. Hermia and George followed suit and expressed their refusal to open champagne at halftime.

Of course, this can't be blamed on Hirsch.

As a representative of COMSOL, his interests are not exactly the same as those of the contestants-

For Hirsch, it is already a win to allow so many teams to enter the finals with such a high ranking.

Even if these teams did not perform well in the finals, that was a problem that the participating teams and schools had to consider.

Even if he exhausted his imagination for his entire life, he could not think of how he could lose.

So in his opinion, celebrating now was not like opening champagne at halftime.

Of course, Hertz was not a person without vision.

Since someone had already refused, he did not insist.

Instead, he began to think about how to build momentum during this period.

After all, being able to gain an advantage on someone else's turf was definitely a once-in-a-lifetime opportunity, and it must be seized...

...

At the same time.

Compared to the jubilant Stanford, the atmosphere in China seemed a little subtle.

Although the influence of this competition has not yet extended to the spectators, there is no good media to make reports such as "This humiliating defeat has become a hot topic in the numerical computing community recently..."

But pairs of eyes in the industry are watching.

You know, in order to avoid possible intellectual property issues, many companies would have bought all the mainstream numerical computing software on the market.

As long as COMSOL can truly demonstrate outstanding performance in the CFD field, there will definitely be many users willing to give it a try.

Although Torch Group has accumulated usage habits and compatibility barriers over the years, it will not lose much of the market immediately, but for high-tech products such as computer software tools, performance is ultimately fundamental.

"Mr. Chang, should we consider making some special changes in response to the situation at COMSOL during the final question setting process?"

Although Song Jingming knew that his boss had planned this for a long time, as a non-technical person, he could not understand the turning point of this plan and how exciting it could be, so he was very panicked at this time:

"I'm worried that if we can't give the other party a strong enough counterattack, it will affect users' confidence in our products..."

Before Chang Haonan could speak, Meng Weizheng, who was in charge of the referee team, also expressed his agreement:

"Yes, Mr. Chang, because the tiebreaker rules are clearly written and a lot of content is disclosed after the game, what we referees can do is limited. For example, the group ranked first in the preliminary round has an advantage of more than 3 points. It is difficult not to Pull it back without letting people notice it.”

"In comparison, COMSOL's software has poor processing capabilities for problems other than CFD. Is it possible to consider setting up some multi-method linkage problems in the finals to offset their advantages in CFD?"

Hearing this, Chang Haonan frowned, fearing that the other party would be too clever to make things worse for him, so he quickly warned in a serious tone:

"I stress again, your referee team doesn't need to do anything, just follow the scoring rules and ensure fair and just scoring!"

As he spoke, he knocked on the table for emphasis.

Seeing this, Meng Weizheng had no choice but to nod, promising that nothing would happen.

"As for the topic of the final..."

Chang Haonan paused for a moment:

"The theme of our conference is CFD, and in the finals, every move we make will be magnified exponentially. If, as you said, in order to offset COMSOL's advantages in CFD, we will focus on other fields. , can’t other experts participating in the conference see it?”

"But……"

Meng Weizheng obviously wanted to say something more, but was interrupted by Chang Haonan waving his hand:

"Although the specific topic of the final cannot be made public yet, I have communicated with several special guests who came to China in advance about the direction of the topic. It is about the calculation of two-phase flow of polymer melt, a 100% CFD problem, so There is no need to say more about this matter.”

In fact, Chang Haonan's initial plan was to simplify the Falcon Z's wing optimization design problem and then apply it.

After all, it was through the engineering documents inadvertently sent by Dassault that he discovered that COMSOL had fatal flaws in calculating the viscoelastic constitutive equation.

But after thinking about it carefully, I felt that the Falcon Z project involved too many commercial secrets, and even if it was simplified, it might not be safe, so I changed my mind and "customized" a new question for my opponent.

The reason why two-phase flow was chosen is that the finite volume method is not good at dealing with systems with drastic changes in interface topology.

Two-phase flow is a typical representative.

However, for general gas and liquid two-phase flows, highly complex viscoelastic constitutive equations are rarely used.

Therefore, he specially selected two relatively rare polymer melts as calculation objects.

A system that is not good at superimposing algorithm flaws.

It can be said that it was targeted deliberately.

From the perspective of outsiders, this is a standard CFD problem.

But in fact, it can directly hit the Achilles heel of COMSOL.

Even the Achilles’ heel that they themselves don’t know——

Chang Haonan himself tried COMSOL several times, and the result was 100% divergent, making it impossible to obtain a valid numerical solution.

Not only that.

If you are unlucky, even the software may crash.

In short, I kept enough shots and just waited for the other party to perform on stage...
