The military-industrial scientific research system of the academic master.

Naturally, Chang Haonan couldn't understand French. After being reminded by the translator who was trying to hold back his laughter, he finally figured out the whole story——

Professor Fernando Lorenzo was fully involved in the development of CATIA software throughout the 80s and early 90s. Apart from Francis Bernard himself, the president of Dassault Systèmes, he was the only person responsible for all versions from version 1 to version 4. . People who are familiar with Windows platform and UNIX platform software.

If Bernard is the father of CATIA, then Lorenzo can be regarded as CATIA's uncle.

However, he did not have a senior position within Dassault, so starting in 93, he was poached by Airbus while holding a teaching position.

At this time, Chang Haonan finally remembered that Lorenzo's paper that he had read in his previous life was about aerodynamic simulation and optimization analysis in 3D CAD software.

And it is not difficult to understand why such a person behaves as if he has seen a ghost when he sees that the software he created has functions that he does not even know about.

This time, this time it was Guan Gong who used a sword in front of his door, and it ended up scaring Guan Gong himself.

Looking at Lorenzo with an "I don't understand" expression on his face, Chang Haonan quickly explained:

"This is not a function of the CATIA software. We just left an interface on the software we developed to output the shape of the result through CATIA's 3D module to save computing resources."

"Huh... no wonder..."

After hearing this statement, Lorenzo finally calmed down a little bit, but the next wave of stormy waves surged up -

There are many icing prediction software in Europe and the United States, from the most widely used LEWICE to ONERA in France, CIRA in Italy, DRA in the UK, FANSAP-ICE in Canada, etc.

But I have never heard of any software that can fully display the ice form directly through 3D models.

(In fact, in 1997, the first version of LWICE 3D had almost been developed, but its performance and effects were terrible, and its user scope was basically limited to a very small number of institutions in North America.)

"Can I operate this model to see how it works?"

After a long silence, Lorenzo asked tentatively.

Chang Haonan nodded:

"Of course, the same operation as CATIA."

At present, this interface only displays the results, and there is nothing that cannot be shown.

Besides, this software is going to be sold commercially in the future, and we are not afraid of showing it to others.

The real core part is the icing mathematical model and corresponding database established based on actual icing phenomena.

In this regard, the more users (even pirated users) who use your own software, the more beneficial it will be for subsequent development.

The bottom line is that while software is easy to pirate, it is not easy to copy.

Not to mention these engineering application software, even if it is available on almost every computer, the seemingly most common Office office suite and its domestic competitor Yinshan WPS are still difficult to fully use in all application scenarios after decades of version iterations. instead of the former.

Colombo put on his glasses and walked to the computer, held down the mouse and slowly dragged the 3D model displayed on the interface.

Due to the performance of the computer, in the eyes of Chang Haonan, a reborn person, the response of the screen is slow, with almost three lags per second. But for people of this era, they don't care about such minor problems as delays and lags.

Although 3D modeling and rendering as a visual representation technology have appeared since the 70s, combining this function with the output module of engineering calculation software has indeed opened up a new track.

"Although I have used CATIA in the past, I never thought it could be used like this..."

Colombo held the Italian's accurate speech gesture with his left hand and sighed to the two companions next to him.

"Me too."

"..."

The three Europeans gathered in front of the small screen, like elementary school students seeing a computer for the first time. While looking at the icing simulation results in novelty, they uttered various exclamations in English, French or Italian.

Chang Haonan stood behind them and showed a successful smile to Lin Guofan next to him.

He knew very well how to deal with these old stubborns from Europe.

There's no need to fix the empty ones.

Just shoot them on the face with something they have never seen before, preferably to create the effect of Grandma Liu entering the Grand View Garden.

As long as these old Europe lose their dignity in front of you, the momentum behind them will be much weaker.

And this software clearly does not disappoint.

"so……"

A few minutes later, the three people who had had enough fun turned around almost at the same time:

"Is this the software you said you wanted to license to us?"

"Yes, that's it, with the basic version of the database."

Looking at the three faces in front of him, Chang Haonan knew that he was basically stable:

"If we sign an agreement, JAA, Airbus, Finmeccanica and ATR will be able to use the software for free before the agreement expires, but other users will still have to pay. Of course, we may also choose to contract with a company Cooperate with local distributors to jointly maintain the commercial operation of the software in Europe."

"The basic version...means there is also an advanced version?"

Lorenzo simply skipped the latter part and accurately captured the key.

"The results you see now are simulated through the basic version of the database. As for the advanced version... it contains more typical climate characteristics and some cutting-edge airfoil data, which will be more efficient to use."

Chang Haonan continued to seduce the other party step by step according to the plan.

"So how do we get the premium version?"

The old professor continued to follow Chang Haonan's guidance and asked.

"Um...is this..."

Although this so-called advanced version does not actually exist yet, Chang Haonan still pretended to be embarrassed:

"To be honest, Professor Lorenzo, the export of advanced software may be restricted by some of our country's policies."

This sentence is even more nonsense. At present, China's legal rights regarding software have not been fully defined, let alone any export regulations.

This was 1997, who dared to think that China could sell software abroad...

But the three people in front of me obviously don't understand this:

"Restrictions set by policy?"

Anne Valette was stunned for a moment:

"Mr. Chang, if the negotiation is successfully completed and the agreement is signed, we will be considered a partnership. Shouldn't we be more open to our partners?"

Chang Haonan chuckled after hearing this——

After going around in a long circle, he finally found the opportunity to say what he wanted to say:

"Since you said we are a partnership, I will be blunt."

“For a long time, many high-end industrial equipment purchased by our country from Europe, such as cold heading machines, stamping machines, and CNC machine tools, can only process products with second-level or even third-level precision. They are obviously the same hardware, and our companies also It cost the same amount of money, but the functions of the industrial control software are limited.”

"We Chinese people are naturally willing to treat our partners with an open mind, but in the face of such chilling differential treatment, we can only adopt some reciprocal measures..."

"Furthermore, there is no difference in core functions between our basic version and advanced version, but the richness of the database is different. Compared with the practices of some of your companies, it is already very benevolent."

After saying this, Chang Haonan glanced at several people.

Even though he was the youngest, he still made the other three people look embarrassed at the same time despite occupying the moral high ground.

"This……"

Of course they knew that what Chang Haonan said was true.

However, this is obviously beyond the scope of the negotiating delegation.

"Of course, I also know that this kind of thing is not something that your delegation can change. It can only be said that each has its own difficulties, but we should seek common ground while reserving differences and not let these difficulties affect our cooperation, right?"

Chang Haonan didn't expect to change the status quo through such an incident.

It's just that someone has to take the first step against unequal contracts.

Now it is just an icing simulation software, so it is naturally impossible to shake so many European industrial companies.

However, the day will come when offense and defense change.

"Yes, I hope this cooperation with you can be successfully completed."

With the step given by Chang Haonan, Colombo also ended the somewhat anxious topic just now.

Obviously, the balance in the hearts of the three people has obviously begun to tilt.
