The Military-industrial Scientific Research System of the Academic Master Chapter 999

Chapter 999: You win, win, win, but in the end you lose everything.

Jameson had a terrible suspicion in his mind at this time.

That is, the algorithm he designed, and of course the COMSOL 2.5 version software developed based on it, has bugs when numerically solving certain types of viscoelastic constitutive equations.

This bug should be so obscure that even he himself doesn't know about it.

But Chang Haonan knew.

Moreover, I already knew it.

If that's the case, then...

The whole game is just one round.

A situation that has been set up.

In the preliminary round, two questions that were most advantageous to COMSOL and did not involve viscoelastic constitutive equations were selected, allowing the participating teams using COMSOL software to achieve results far beyond expectations.

This is equivalent to lowering their vigilance and luring the enemy deeper.

The final is the real killer move.

Two-phase flow calculation, pure CFD problem.

It seems that COMSOL still takes advantage.

But as long as that BUG can be triggered, the results of all teams using COMSOL can collapse.

It may even be impossible to achieve results at all!

Of course, if we want to explain this chain of thinking clearly, it will take at least ten minutes.

Therefore, Jameson asked Hermia to see the calculation results without saying anything.

If everything is normal, it proves that his worries are unfounded.

As for bugs, even if they exist, they can be fixed slowly.

And if the result cannot be calculated, or there is something obviously wrong with the result...

Then there is no need to worry about BUG for the time being.

Just prepare for public opinion and public relations...

Professor Jameson didn't even know how he got out of the elevator.

When he came back to his senses, he found himself sitting on the sofa at the front desk of the hotel.

He couldn't think too much and quickly touched his pocket, only to find that he didn't have his phone with him.

So he hurriedly rushed to the front desk, borrowed the landline phone and dialed Heltz's phone number...

At the same time, Hermia also hurriedly returned to the computer room,

Although she was still confused, Jameson's abnormal behavior just now made her understand that the situation should be very serious.

Sure enough, when she pushed open the compartment door, she found the other two people sitting in front of Unit 3 with livid faces, as motionless as two statues...

"Lemmy?"

"Jo?"

She called twice tentatively.

Hearing Hermia's voice, Lyles's body swayed slightly, and then he turned his head stiffly like a robot:

"Hermie, I think we're...in trouble."

Hermia, who had already had an ominous premonition, twitched the corner of her mouth and her heart sank:

"What exactly happened?"

With that said, he walked back to his own Unit 3.

On the screen was the calculation she started before she went to take a break.

Now, the results have come out as she expected.

But not completely.

because…

"Computational divergence?"

Hermia also showed a ghostly expression:

"How is that possible?"

The computer room was eerily quiet for a while.

Only the faint squeaking sound of the hard drive occasionally sounded.

"Actually...this is our second calculation."

George replied in a hoarse voice:

"At three o'clock in the afternoon, the calculation you made before you left has already gone wrong."

"Later, we adjusted the boundary conditions and starting point and tried again, but the result... was still divergent."

Once a problem occurs, it may be caused by accidental factors or simply careless input errors.

But if the same problem occurs twice in a row, there are only two possibilities.

Either there is something wrong with the method.

Either there is something wrong with the tool.

but…

It doesn't really matter anymore.

Because it is already the evening of the second day.

There are only 15 hours left to submit your answer.

Compared with those teams that discovered problems early and reworked early, they didn't even have the chance to start over and deliver a semi-finished product.

Lyles's face was horribly ugly—

Just a few hours ago, he was condescendingly judging other teams in trouble, as if he was not involved.

However, when the same situation happened to him, he found no warning.

Let alone think of a solution.

"Hermie." A few minutes later, Lyles finally came back to his senses and looked at Hermia behind him:

"Go to Professor Jameson quickly and see if he has a solution..."

Hermia thought about Jameson's performance just now and felt that the possibility was probably very small.

The professor must have just realized something was wrong.

It is impossible to think of a solution in an instant.

Besides, even if you think about it, you may not have time to change it.

George next to him was a little hesitant:

"You can follow the rules of the competition..."

"Never mind that!"

Lyles growled lowly:

"Before we solve the problem, we must at least submit a valid result!"

"Besides, I'm just asking the professor for ideas. If I don't bring a storage device, the competition won't find it..."

He used to tend to abide by the rules because he felt that he had great advantages and could get good results even if he abided by the rules.

But now that he is at a disadvantage, he has naturally forgotten those things long ago.

Hermia hesitated for a moment, then turned around and ran out again...

However, the result was pretty much what she had expected.

Jameson was silent for a long time when he heard Hermia say that their calculation results were divergent and could not converge no matter how they adjusted the input settings.

In the end, he just sighed.

As for Heltz next to him, he slumped down on the sofa.

In fact, it stands to reason that if there is a bug in something like software, or it is an unpopular bug that no one has reported for half a year, it should not be a big deal at all.

But the problem is that in the month between the preliminary rounds and the finals, he created a lot of momentum.

Now even the awesomeness has been blown out.

The top three guaranteed have also taken out loans.

Everyone is waiting to see your dazzling performance.

The result was pulled.

That's a pure clown.

All previous publicity, all intentional or unintentional belittling of Torch Group, and even all intended orders.

They will all turn into boomerangs, piercing their heads one by one.

Anyone who has been in the rice circle knows this truth.

The most terrifying backlash is called turning from pink to black...

No matter how you explain it, it can't change the fact that COMSOL Multiphysics is embarrassed in public and has been thrown out of the horizon.

Every user will think about what happened in this competition before using it.

And this is not even the most embarrassing thing -

Two days later, the entire industry will know that the bug that COMSOL did not even discover has been solved by Torch Group...

It is impossible to eliminate this negative effect within a few years.

Considering the development speed of Torch Group and the entire numerical computing industry, in a few years...

Fuck you, who still remembers who you are at COMSOL?

"Professor, is there really nothing you can do?"

asked Hermia, who was still a little unwilling to give up.

Jameson closed his eyes in pain and shook his head.

After a while, he finally explained:

"At present, we can only determine that the problem should be in the process of solving the viscoelastic constitutive equation. After the stability representing elasticity increases to a certain critical value, the numerical solution will produce non-physical oscillations in the area of rapid stress change, causing the algorithm to fail. Stable, computing crashes."

"But why this happened...it will take about two days to know."

Why can we find out in two days?

Because Chang Haonan has to give a report in two days...

You will naturally know after listening to it.

Of course, Jameson didn't say this.

However, for Hermia, the result was already clear—

Even the reason cannot be found, and the solution is even more fanciful.

She didn't stand still and sat directly on the bed:

"Then...then our final results aren't..."

No one answered.

Finally, it was Jameson who added this sentence:

"Don't worry...I will help you bear the cost of this trip to China..."

This sentence is almost a disguised admission.

No choice.

Just wait to die.

Hermia, who was sitting on the bed, opened her mouth.

She really wanted to say that the three of them came to China not for tourism, so what was the use of paying for the travel expenses...

But in the end, looking at Jameson and Heltz who were also lost, she swallowed these words back...

"knew…"

Hermia supported the edge of the bed and stood up again unsteadily:

"I'll go tell them about the situation..."
