Chapter 493: With just a few moves, I am already at the pinnacle of this era!
The localization and improvement work of the J-11 aircraft is complicated, and structural upgrades are not the only thing that can be done.
So after receiving Chang Haonan's "suggestion", Institute 601 and Factory 112 quickly began to take action and adjusted their work focus in the recent period.
Chang Haonan, after a short vacation, flew back to the capital.
With the system of colleges and universities, if nothing else, holidays can still be guaranteed.
In 1997, the "National Holidays and Anniversary Days" that had been promulgated and implemented in 1949 was still implemented nationwide. There were only two days of holidays on November 1st.
Fortunately, since 1995, double holidays have been implemented every week, so including a weekend, I can take four days off.
A little closer to home, you can go back to your last trip here.
So when Chang Haonan came back to the computing center of Beijing Hang University and gathered the technical staff involved in software maintenance and updates for a meeting, it was already after the four-day holiday of National Day.
"Is this going to be a version update?"
After hearing about the sudden software plan at the morning meeting, the first reaction of most people was similar to that of He Ming a few days ago.
Chang Haonan sat at the head of the conference room and glanced at the dozen business backbones in front of him who were divided into two rows and sat opposite each other:
"The new grid generation method will be updated to the professional upgraded version first. For users, the professional version only retains relevant basic functions.”
“The users of this professional upgraded version are highly professional universities and scientific research institutions involved in military projects, and their independent capabilities are relatively relatively high. Strong, there shouldn’t be too many situations where we need 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 grid generation method based on unstructured grid methods has nothing new about the time and space discretization methods in the subsequent calculation process. requirements, so basically only the grid generation module needs to be overhauled, and other parts will not change much. "
At this time, the benefits of clear thinking in the previous software design are reflected.
If it is some shitty code, then if it affects the whole body, such a big functional change may require the software to be rewritten...
"Oh...it's okay. …”
At this time, except for a few people in charge of the grid generation module, everyone else breathed a sigh of relief.
No matter what age you are working in software, the working conditions are the same.
As long as you have a project, just working overtime is easy.
Sleeping in the workplace is commonplace.
Some people who are familiar with each other have even begun to joke about Tian Zhaoyi, the person in charge of the grid generation module who is sitting blankly:
"Come on, man..."
Someone tapped him on the shoulder.
"Think on the bright side, our company pays overtime pay..."
Someone sighed with a concerned expression on their face.
“Yeah, it’s almost the end of the year, it would be nice to make some extra money to go home to my wife and children for the New Year...”
Some people even sounded a little envious.
“…”
Human beings’ joys and sorrows are not the same, I just think they are noisy.jpg
However, before they were happy, Chang Haonan started talking. Reposted:
“You don’t have to envy them...overtime pay, everyone can have it...”
After hearing these words, everyone who had been joking lightly just now had smiles instantly solidified on their faces.
“Over this period of time, there have been a lot of feedback and suggestions from users. I just took this opportunity to revise these places together. I have probably seen them, but they don’t count. What a big problem, try to release the first iteration of the new version within this month!”
People, don’t worry about the shortage but the inequality.
Now everyone has overtime and money, so I don’t feel there is any imbalance.
Moreover, after the trial version of the software was released, most of the staff who were seconded to participate in the development returned to their original units.
The people who are still here are all those who have directly transferred their working relationships.
I will choose to give up the stable job in the research institute. At this time, it seems that the first meal may not necessarily lead to the next meal. The new state-owned enterprises who join the company are more or less interested in TORCH Multiphysics, and even the entire field of numerical calculation.
Academician Li Jie of the Institute of Computing Technology has acted with integrity in this matter, allowing everyone to choose whether to stay or leave on their own, which is a strong support for the Torch Group.
Of course, it can be regarded as thanks to Chang Haonan for helping him open up the nationwide supercomputing and server market.
Shuguang Group, which could only rely on financial allocations to survive last year and even considered selling part of its shares to Dream Company to raise funds, has achieved positive profits this year. Although it may not seem like a big deal at the moment, it is the beginning of Chang Haonan wielding a hoe against the former.
......
After deploying some less important tasks, Chang Haonan asked the heads of other modules and businesses to go back to work first.
Only a few backbones responsible for the grid generation module were left.
Although in the early stages of software development, he required all personnel involved in R&D to understand the basic situation of other parts, this was mainly to avoid some compatibility problems during the development process of different modules.
Nowadays, software upgrade and maintenance work has become highly specialized, and the knowledge and skills required between different modules vary widely. Except for a very small number of people, it is no longer necessary or possible to understand everything.
"Mr. Chang, in terms of generation logic, what is the specific difference between this non-structured overlapping grid method and the previous old method?"
There was only one person left in the entire conference room. After a few knowledgeable people, the person in charge, Tian Zhaoyi, got right to the point.
The time is tight and the task is heavy. In addition, this is an area that he has never touched before.
It feels like I have gone back to the time when I was just studying for graduate school many years ago.
"Is there any literature that I can use for reference?"
An assistant next to him also asked.
Generally, when researchers want to enter a new field that they have never explored before, they will start with some review literature to get a general understanding first, and then dig into the specific research bit by bit. content in the direction.
“No.”
Chang Haonan shook his head decisively:
"Actually, even this term was casually thought of by me some time ago."
The expressions of the people opposite were stagnant.
Well, it’s our boss’ first initiative again.
In the past few months after joining Torch Group, they have encountered more "original" technologies than in their entire careers.
“However, the unstructured overlapping grid method is the same as the structural overlapping grid method. Before performing the flow field calculation, the overlapping grid system assembly is required, that is, digging holes and determining the inter-grid interpolation boundaries and their hosts. unit.”
Chang Haonan said, opening the notebook on the table in front of him.
As the research content becomes more and more in-depth, even he himself can no longer solve all the problems by brainstorming alone, especially when he does not have enough scientific research points to directly use the system to solve the problem. It is even more necessary to sort out some ideas systematically:
“The difficulty is that there are no topological relationships between grid units and grid nodes in non-structured grids like in structured grids, so dynamic and automatic Parts such as grid assembly, efficient search technology and inter-grid interpolation all require new algorithms to complete.”
“The three most important parts are the classification and network of grid nodes. The definition of inter-grid boundaries, the second is the search of host units, and the third is the reconstruction of inter-grid interpolation boundaries..."
While introducing his ideas to several people, Chang Haonan was also imagining other ideas in his mind. One thing.
In engineering practice, the core of the new version of TORC Multiphysics is to use limited memory and computing time to implement this complex non-structured overlapping grid generation method, 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.
That is, the concept itself of "unstructured overlapping grid".
So, he was thinking about how to promote this concept.
After much deliberation, I still can only use some leftover results to publish a paper——
Look, I have a very cool numerical simulation theory here.
What? Do you want to do research but don’t have the tools?
That’s easy to say, I have it here. You can buy it and try it out first. You can experience this new method of mine and I’m definitely not bragging.
However, the publicly released professional version does not provide supporting follow-up algorithms for the time being, and can only be used for theoretical research
If you want to use this method to solve practical problems...
Sorry, that can't be done.
You can choose to wait, the updated content of the professional version may be 1-2 years behind the level.
If you are not willing to wait, you can also refer to the Italians and choose to cooperate with Chinese institutions or companies that have professional upgraded version authorization.
Or our Torch Group can also undertake related numerical calculation business.
It’s just that research and development results need to be shared to a certain extent.
This...you guys shouldn't have any objections, right?
