The Military-industrial Scientific Research System of the Academic Master Chapter 994

Chapter 994 Finals Preparation (New January, please vote for me~)

In Hertz's original vision, although the title of the competition was very beneficial to his own side, after all, from the referee to the organizer, to the co-organizer and the witness, all the units were members of the Torch Group. How could you compete with them?

Especially in this kind of competition where the scoring method is extremely complicated.

Just changing a little bit in any detail is enough to change the entire result.

It's not like they haven't done this kind of thing before.

The experience is so rich.

Therefore, Hertz's best expectation at the beginning was that about a dozen teams using COMSOL software would represent their own schools or research institutions in the finals—

As long as you can show your own banner in the competition held by the opponent, you will be considered a victory.

However, the final result was a big one for him.

Two of the top three teams are from our own team.

Four of the top ten teams are from our own team.

As for what's next…

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

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

This is no longer a banner.

This is planting the flag in the opponent's base camp.

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

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

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

The group including Santa Clara University next door, although their results were slightly lower and to a considerable extent improvised, still reached 31st overall ranking.

Representing the school also entered the finals without any suspense.

And, it's not just that.

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

There are now almost three weeks until the finals.

This means that some teams may temporarily decide to change the calculation software after seeing the preliminary results.

Or at least be more prepared.

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

Even... mainstream!

Thinking of this, Herz seemed to have already seen the day when he would step on ANSYS, get promoted and get a raise, and reach the pinnacle of his life.

"I think it's okay to celebrate."

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

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

On the contrary, the three students showed amazing calmness.

"I think the focus right now is still preparing for the finals."

Lyles Connor clenched his fists. It was obvious that he had not gotten over the excitement just now, but he still tried his best to appear calm:

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

"Moreover, this result still takes advantage of the questions to a large extent. We cannot expect that we will have such good luck in the finals, so we still need to increase training on special types of questions during this period, such as the first question in the preliminary round If you encounter such a particle flow problem in the finals, you won't have the opportunity to choose two out of three..."

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

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

Of course, this cannot be blamed on Hertz.

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

For Hertz, having so many teams advance to the finals with such a high ranking is already a win.

Even if the results of these teams in the finals are not ideal, that is still an issue that participating teams and schools need to consider.

Even if I exhaust my life's imagination, I can't imagine how I could lose.

So in his view, celebrating now doesn't count as opening champagne at halftime. Of course, Hertz is not the one without vision.

Since someone had already expressed rejection, he didn't insist anymore.

Instead, I started thinking about how to use this time to build momentum.

After all, being able to gain an advantage on someone else's territory is definitely a once-in-lifetime opportunity, and you must seize it...

at the same time.

Compared to the jubilant Stanford, the atmosphere here in China seems a bit subtle.

Although the influence of this competition has not yet extended to the melon-eating masses, there is no good media to report 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 will buy all the mainstream numerical calculation software on the market.

As long as COMSOL can really show outstanding performance in the CFD field, there will definitely be many users willing to try it.

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 question setting process for the finals?"

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...
