Chang Haonan naturally couldn't understand French, and after a hard translation reminder with a smile next to him, he figured out the ins and outs of this matter-

Professor Fernando Lorenzo, who was involved in the development of CATIA software throughout the 80's and early 90's, was the only person to be responsible for all versions 1 to 4, Windows and UNIX platforms, with the exception of Francis Bernard, president of Dassault Systèmes.

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

It's just that he didn't have a senior position within Dassault, so from 93 onwards, he was poached by Airbus while also serving as a teacher.

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

And it's not difficult to understand that such a person behaves like a ghost when he sees a function in the software he has made that he doesn't even know about.

This time, this time it was Guan Gong playing with a big knife at the door, and it scared Guan Gong himself.

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

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

"Whew...... No wonder ......"

Hearing this, Lorenzo's heart finally calmed down a little, but the next wave of turbulence followed-

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

But I've never heard of a software that can fully display the ice form directly through a 3D model.

(In fact, by 1997, the original version of LWICE 3D was almost complete, but the performance and results were disastrous, and users were largely limited to a very small number of institutions in North America.) ）

"Can I manipulate this model?"

After a long silence, Lorenzo asked tentatively.

Chang Haonan nodded:

"Of course, it's the same as CATIA."

At the moment, this interface only shows the results, and there is nothing that cannot be revealed.

Besides, this set of software is ready to be sold commercially in the future, and it is not afraid to be shown to others.

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

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

At the end of the day, while software is easy to pirate, it's not easy to borrow.

Not to mention these engineering application software, even if almost every computer has it, it seems that the most ordinary Office office suite, its domestic competitor Yinshan WPS after decades of version iteration, it is still difficult to completely replace the former in all application scenarios.

Colombo put on his glasses and walked to the computer, holding down the mouse and slowly dragging 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 picture can be called sluggish, almost three cards per second, but for people of this era, they don't care about the small problem of delay and jamming at all.

Although 3D modeling and rendering as a visual representation technology has been around since the 70s, combining this feature with the output module of engineering computing software does break new ground.

"I've used CATIA in the past, but I never thought I'd be able to use it again......"

Colombo pinched the Italian's quasi-gesture with his left hand and sighed to the two companions next to him.

"Me too."

“……”

Three Europeans gathered in front of the tiny screen, like schoolchildren who had seen a computer for the first time, watching the results of the icing simulation with novelty and mouthing various interjections in English, French or Italian.

Chang Haonan stood behind them and smiled at Lin Guofan next to him.

He knew too well how to deal with these old European stubbornness.

Don't fix those imaginary things.

is to directly take something they have never seen before and shoot it on the face, and it is best to show the effect of Grandma Liu's entry into the Grand View Garden.

As long as these old Europeans 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 who had had had enough of it turned back almost at the same time:

"This is the software you said you were going to license to us?"

"That's right, this is 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 the agreement, JAA, Airbus, Finmecanica Group and ATR will be able to use the software for free until the agreement expires, but other users will still have to pay for it, and of course, we may also choose to work with a local distributor to maintain the commercial operation of the software in Europe."

"Base Version...... Meaning there's also a premium version? ”

Lorenzo skimmed over the back and caught the key to the point.

"The results you're seeing now are simulated from the Basic Edition database, as for the Advanced Edition...... It will be more efficient to use more typical climatic characteristics and some cutting-edge airfoil data. ”

Chang Haonan continued to follow the plan, seducing the other party step by step.

"So how do we get the premium version?"

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

"Hmm...... What ...... this?"

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

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

At present, Huaxia has not even fully defined the legal rights of software, and it is impossible for there to be any export regulations.

This is 1997, who dares to think that Huaxia can sell software abroad......

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

"Policy restrictions?"

Anne Valette was stunned for a moment:

"Mr. Chang, if the negotiations are successfully completed and the agreement is signed, we can be regarded as a partnership, shouldn't we be more open to partners?"

Chang Haonan chuckled when he heard this-

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

"Since you said we were a partnership, then I would be blunt."

"For a long time, many high-end industrial equipment purchased by China from Europe, such as cold heading machines, stamping machines, CNC machine tools, can only process secondary or even tertiary precision products, which are exactly the same hardware, and our enterprises have spent the same amount of money, but the function of industrial control software is limited."

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

"And there is no difference between our basic version and the advanced version in terms of core functions, but the richness of the database is different, which is very benevolent compared to the practices of some of your enterprises."

After saying this, Chang Haonan's gaze swept over several people.

Although he was the youngest, he still made the other three of them embarrassed at the same time when he occupied the moral high ground.

"This ......"

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

However, this is clearly beyond the purview of the current negotiating delegation.

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

Chang Haonan didn't expect to change the status quo through such a thing.

It's just that the first step in the fight against unequal contracts has to be taken.

Now it's just an icing simulation software, and naturally it can't shake so many European industrial companies.

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

"That's right, and I hope that this cooperation with you can be successfully concluded."

With the steps given by Chang Haonan, Colombo also took the opportunity to end the topic that had just been a little anxious.

Obviously, the scales in the hearts of the three people have obviously begun to tilt.
