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

"So...Dr. Chang, you already have a plan in this regard?"

Xu Yang's voice was a little dry, but she didn't care so much anymore.

If the idea just mentioned by the other party can come true, it will definitely trigger a major earthquake in the field of numerical computing applications.

"We can't talk about the plan yet. We can only say that we have some preliminary ideas. We are still a little far away from the plan. We need to fill in some theoretical and experimental gaps."

Chang Haonan shook his head. Even with systematic help, he would not be that awesome.

This should be a somewhat lengthy, step-by-step process.

After all, if he alone, or a few people around him, conduct experiments and collect data, then he may not be able to optimize what he wants in the next life.

Therefore, a wiser choice would be to create the most basic version first, and then rely on the entire industry to provide feedback and upgrade step by step...

It seems to be similar to the thinking of some car companies before his rebirth.

New car launches are all cake, and all features have to wait for OTA.

cough cough...

In short, although there is some controversy in the cycling circle, the routine itself is not problematic.

As the functions of software become more and more complex, it is gradually becoming unfeasible in terms of technology and cost to release a so-called "complete version" in one step. Instead of forcing a semi-finished product with comprehensive functions but poor reliability, it is better to specialize first Focus on polishing a few specific modules, gain users and reputation, and then gradually expand.

And he just borrowed a little bit from the Internet thinking more than 20 years later.

"Numerical simulation of multi-physics coupling is still a blank in the world. As far as I know, only a few schools have some very simple tool kits. If a breakthrough can be made in this area, it will definitely be possible." A major event that affects the entire industry!”

Xu Yang looked at Chang Haonan beside him with bright eyes.

"This is true, but the first step is to be down-to-earth."

Chang Haonan expressed his thoughts:

"First, we simulate several commonly used single physical fields such as heat transfer phase change, structural mechanics, fluid mechanics, and electromagnetic fields, as well as weak simulations involving 2-3 physical fields such as convection diffusion, convective heat transfer, thermoelectric coupling, and fluid-solid coupling. Once the coupling problem is solved, we can gradually overcome the problems of more physical fields and stronger coupling.”

"But if that's the case..."

Xu Yang frowned slightly when he heard this:

"Dr. Chang, you should also know that almost all single-physics simulations now have relatively mature solutions, and weak coupling problems with low nonlinearity can also be solved through brief coupling or full coupling. I am afraid that for new It won’t be very attractive to users…”

Of course what she said makes sense.

Human beings are all inert, and they will stay the same if they can.

This is especially true in the engineering field.

Before Chang Haonan was reborn, there were even some engineering software that had not been updated all year round and only supported the Windows 98 system, so that their research institute had always kept an old computer that could be called a cultural relic.

But the problem is that, similar to the situation with civil aircraft airworthiness certification, if you don’t seek changes now and do the same thing again in the future, the price you pay will be hundreds and thousands of times higher.

Chang Haonan, who has experienced this once, knows this very well.

On the one hand, it is early 1997. Although the relevant industrial software in Western developed countries has been developed for about 20-30 years, it has just begun, or has not yet begun to think about commercialization. Everyone is still on the same page. On the starting line.

On the other hand, in China, only universities, research institutes and state-owned enterprises that use commercial software extensively in China are places that can be reached by administrative orders, and the relevant software ecological barriers have not yet been established.

In fact, China's own semiconductor industry and software industry were not established very late. They have already improved in the early 80s. The gap with Neon is about 5 years. Although it is not advanced, it can still be regarded as advanced. It has formed its own industrial system.

However, like many industries, the budding signs of development have been suppressed.

Without top-down support and without a mature business model, scientific research, education, and industry were quickly isolated.

Hardware manufacturing plants have become assembly lines that provide cheap labor for foreign companies, and the software industry has completely become a vassal of others. A large number of software engineers who originally developed software independently have become ordinary low-level code farmers.

Only some research institutes and schools are left to continue research, but they are also unable to support themselves. After losing their ecology, they are increasingly disconnected from actual production.

It was not until more than twenty years later that due to various reasons, we finally paid attention to this aspect again.

In fact, a similar situation also occurred with Maozi after the disintegration.

In 1990, Mao Xiong's electronics industry was probably equivalent to the level of the United States in about 85.

But by 2000, they were still stuck at the level of Americans in 85, and completely missed the explosion of the information industry in the entire 90s (actually it was even worse, because they didn't even have the opportunity to follow other people's standards).

It was also more than 20 years later, due to sanctions, that the industry was revived. By that time, it had already lagged behind the advanced level for many years.

In short, it was difficult for people in 1997 to understand the bitterness and sorrow involved.

For Chang Haonan, who was reborn, it was not too late to make amends.

He really doesn’t understand semiconductors at all now, so he should start with industrial software.

"If we only consider it from a technical perspective, Researcher Xu is right."

Chang Haonan used a more euphemistic expression. After all, no matter how talented a person is, it is difficult to transcend the times. It is normal to have the kind of thoughts just now.

Xu Yang could naturally tell that Chang Haonan had different opinions from hers, but considering the other party's ability, she just showed a somewhat curious expression:

"But industrial software is not entirely a technical issue, otherwise there would be no Wassenaar Agreement."

“Now that we use foreign software, we really don’t feel any inconvenience other than the language barrier. But that’s because many software have not yet been commercialized, or are in the process of expanding the market in the early stages of commercialization. But if we continue to let These foreign companies are attacking our city and territory unscrupulously, and there is no telling what will happen in the future.”

“Right now, everyone’s starting point is pretty much the same, but the information industry is developing so fast. The more users an industrial software has, the more information feedback the developers will get, and a database with larger quantity and higher quality will be formed. This will lead to the development of a more useful data model. If we cannot keep up with this step, we will not be able to keep up with each step. If one day in the future, some industrial software suddenly appears in the Wassenaar Agreement, we will think about it at that time. To pursue it from scratch and accumulate data is much more difficult than reaching the sky.”

The powerful words made the atmosphere around the entire table become a little heavy.

Xu Yang, who was a little unimpressed just now, his pupils trembled after hearing this, as if he had seen a new continent.

She would choose to return to China from the United States in the early 90s, and she naturally had no shortage of feelings about her family and country.

But many things are not just about feelings.

The struggle on the scientific and technological front is also a struggle, and it requires skills and strategies.

In this regard, obviously no one can compare with Chang Haonan, who has experienced the trade war era.

"In fact, we have made a breakthrough in the export of industrial software."

Looking at everyone who was lost in thought, Chang Haonan once again dropped a bombshell.

Anyway, the people sitting here have sufficient authority.

"Industrial software...export?"

Xu Yang, who was outside the aviation industry system and had no idea about China's negotiations with Europe, felt that for the first time in his life, his mind was a little out of control.

You know, China's software industry is still at a stage where it doesn't even understand the localization of the UI interface.

Why was it exported?

Chang Haonan nodded:

"Yes, a small software that predicts the icing probability and ice type of aircraft in humid and cold environments is not our first creation, but its functions are definitely better than any foreign competing products, and it is sold to Europeans."

"This shows that as long as we can create unique functions or features, we can completely defeat others in the software field!"

In fact, considering this was at the dinner table, he still had half a sentence left to say——

Anyway, the performance of everyone's products now relies on defense. Even if what we make is a defense, as long as it is made into chocolate flavor, some people will pinch their noses and eat it.

At this time, on the other side of the dinner table, Sun Cong, who had been listening to the conversation between the two just now, suddenly said:

"I have also heard about this matter, but I have never been sure whether it is true or not. Now that Comrade Xiao Chang has said it, it is indeed a huge breakthrough..."

With the praise, Chang Haonan naturally accepted it:

"Of course, this time we have indeed taken a rare opportunity to create discord between Europe and the United States. No one can guarantee that other subsequent software will have such a good response internationally."

"However, what I want to say is that when it comes to industrial software, including but not limited to it, we must have bottom-line thinking and cannot let others hold our necks!"
