The localization and improvement of the J-11 aircraft are complicated, and it is not only the structural upgrade that can be done.

Therefore, after receiving Chang Haonan's "suggestion", the 601 Institute and the 112 factory soon began to take action and adjusted the focus of work in the recent period.

Chang Haonan, on the other hand, flew back to the capital after a short vacation.

The system of colleges and universities, not to mention anything else, can still guarantee holidays.

In 1997, the "Measures for Holidays on National Festivals and Memorial Days" promulgated and implemented in 1949 were implemented nationwide, and there were only two days off in November.

Fortunately, since 1995, two days off a week have been implemented, so counting one weekend, you can take four days off.

If you're a little closer to home, you'll be able to go back home.

So when Chang Haonan came back to the computing center of Jinghang University and gathered the technicians involved in software maintenance and update for a meeting, it was already after the four-day holiday of the eleventh day.

"This is going to be updated?"

After hearing the sudden software plan at the morning meeting, the first reaction of most people was similar to He Ming a few days ago.

Chang Haonan sat at the head of the conference room, and his eyes swept over the dozen or so business backbones who were divided into two rows in front of him:

"The new grid generation method is first updated to users of the Professional Plus version, and the Professional version only retains the relevant basic functions."

"The users of this part of the professional upgrade version are all highly professional, universities and scientific research institutions involved in military projects, and their independent ability is relatively strong, so there should not be too many situations that require us to send people to upgrade."

The person in charge of the after-sales business finally looked a little better.

After taking a sip of water, Chang Haonan continued:

"In addition, this overlapping mesh generation method based on the unstructured mesh method has no new requirements for the time and space discretization method of the subsequent calculation process, so basically only the mesh generation module needs to be greatly changed, and the other parts do not change much."

In this case, the benefits of clear thinking in the previous software design are reflected.

If it's some mountain code, then it will be a big change in the whole body, and this kind of big functional change may mean that the software will have to be rewritten again......

"Oh...... Ok......"

At this moment, except for a few people in charge of the grid generation module, everyone else breathed a sigh of relief.

Those who are engaged in software, no matter what age they are, work in a similar state.

As long as you come to the project, it's easy to work overtime.

Sleeping in the unit is commonplace.

And some people who are more familiar with each other, and have even begun to joke about Tian Zhaoyi, the person in charge of the grid generation module who is sitting in a daze:

"Come on, dude......"

Someone tapped him on the shoulder.

"On the bright side, our company pays overtime ......"

Someone sighed, a look of concern on his face.

"Yes, it's almost the end of the year, so it's good to earn more money and go home for my wife and children for the New Year......"

There are even people with a little envy in their tone.

“……”

The joys and sorrows of human beings are not the same, I just think they are noisy .jpg

However, before they could finish their happiness, Chang Haonan changed his words:

"You don't have to envy them...... Overtime pay, everyone can have ......"

Hearing this, the smiles of the people who were still teasing them easily just now instantly froze on their faces.

"During this period of time, there are a lot of opinions and suggestions from users, just take this opportunity to modify these places together, I have probably seen it, it is not a big problem, and strive to release the first iteration of the new version within this month!"

People don't suffer from widowhood but from inequality.

Now that everyone has Banga and money, I don't feel any imbalance.

Moreover, after the release of the trial software, most of the personnel who had been seconded to participate in the development at that time returned to their original units.

The people who are still here are the people who have directly transferred their working relationships.

They will choose to give up their stable jobs at the institute, and it seems that the new state-owned enterprises that have eaten the last meal may not have the next meal to join the company, and they are more or less interested in TORCH Multiphysics and even the entire field of numerical computing.

Academician Li Jie of the Institute of Computing Technology has performed well in this matter, allowing everyone to choose to stay or go, which can be regarded as a fierce support for the Torch Group.

Of course, it can be regarded as a thank you to Chang Haonan for helping him open up the nationwide supercomputing and server market.

Shuguang Group, which could only rely on financial appropriations last year to survive and even considered selling some of its shares to Dream Company to raise funds, has already achieved positive profits this year.

Although it doesn't seem like a big deal at the moment, it is the beginning of Chang Haonan wielding a hoe to dig the foot of the wall against the former.

……

After deploying some less important work, Chang Haonan asked the heads of other modules and businesses to go back to work first.

Only a few backbones in charge of the mesh generation module were left.

Although in the early stages of software development, he requires all those involved in the development to understand the basics of the other parts, but that is mainly to avoid some compatibility problems in the development of different modules.

Software upgrades and maintenance are highly specialized, and the knowledge and skills required vary greatly from module to module, making it unnecessary or impossible to understand the full range except for a very small number of people.

"Mr. Chang, what are the specific differences between this non-structural overlapping grid method and the old method in terms of generation logic?"

After there were only a few knowledgeable people left in the entire conference room, the person in charge, Tian Zhaoyi, went straight to the point.

Time was tight, and the task was heavy, and it was an area he hadn't touched before.

It feels like I've gone back to when I was in graduate school many years ago.

"Is there any literature that you can refer to?"

An assistant next to him also asked.

Under normal circumstances, when researchers want to enter a new field that they have never set foot in, they will start with some review literature, first have a general understanding, and then gnaw at the content of the specific research direction little by little.

"Nope."

Chang Haonan shook his head decisively:

"Actually, even this term was a random one I came up with some time ago."

The expressions of several people on the other side froze.

Well, it's our boss's first initiative.

In the few months they have been with Torch Group, they have encountered more "original" technologies than they have ever done in their entire careers.

"However, the unstructured overlapping mesh method, like the structural overlapping mesh method, requires the assembly of the overlapping mesh system, i.e., digging holes and determining the interpolation boundary between the meshes and their host elements, before proceeding with the flow field calculations."

Chang Haonan said and flipped through the notebook on the table in front of him.

With the deepening of the research content, even he himself has no way to solve all the problems by brainstorming, especially in the current situation where the scientific research points are not enough and there is no way to directly solve the problem with the system, he needs to systematically sort out some ideas:

"The difficulty is that there is no topological relationship between the grid elements and between the grid nodes of the unstructured mesh, so the dynamic automatic mesh assembly, efficient search technology, and interpolation between the meshes all need new algorithms."

"The three most important parts are the classification of grid nodes and the definition of inter-grid boundaries, the second is the search of host units, and the third is the reconstruction of interpolation boundaries between meshes......"

Chang Haonan introduced his ideas to several people, and at the same time, he was also thinking about another thing in his mind.

In terms of engineering practice, the core of the new version of TORCH Multiphysics is to implement this complex unstructured overlapping mesh generation method with limited memory and computation time, focusing on the parallel computing technology that has been applied in the software.

But academically, the focus is on the front, the part he has already written in his notebook.

This is the concept of "unstructured overlapping mesh" itself.

So, he's thinking about how to get the concept out there.

After thinking about it, I can only use the results of some leftovers to send a paper-

Look, I've got a pretty awesome theory of numerical simulation here.

What? You also want to research, but don't have the tools?

That's good, I have it here, you can buy it back and try it first, and experience my new method is definitely not blowing.

However, the professional version released by the public does not provide supporting follow-up algorithms for the time being, and can only be used for theoretical research

If you want to solve a real problem in this way......

Sorry, this can't be done.

You can choose to wait, the update content of the Pro version may be 1-2 years behind.

If you are not willing to wait, you can also refer to the Italians and choose to cooperate with a Chinese institution or enterprise with professional enhancement authorization.

Or we in the Torch Group also undertake related numerical calculation business.

It's just that R&D results need to be shared to a certain extent.

This...... You don't think you have an opinion, do you?
