Chapter 496 Why not contact the author himself?
An article left Professor Elinor scratching his head and scratching his head.
He is basically certain that if the unstructured overlapping grid technology mentioned in the paper is applied to several ongoing projects at hand, it can greatly improve computational efficiency.
But the content that ends abruptly seems like the author is deliberately tempting his peers.
Obviously we are already standing in front of the door to the new world.
But...
No key!
“Huh——”
After taking several deep breaths, Elinor calmed down a little bit from his dissatisfaction.
As a senior professor with a high level of research, he does not have to wait for others to put things into his mouth.
There is still some subjective initiative.
According to Elinor's estimation, an additional toolkit or new program may be needed to adapt to this never-before-seen grid technology.
Although the professor himself is not an expert in software programming, he still has the vision.
Furthermore, he has been immersed in the aviation field for many years and has absolutely no shortage of contacts, especially in Europe.
So, after thinking for a moment, Elinor forwarded the paper to another email address and attached some of his own thoughts at the end.
After doing this, he leaned back in his chair and began to think about what review comments he should give.
But after thinking about it for a long time, I really didn’t find any comments that I could write.
The author's theoretical foundation is quite profound, and the overall structure and reasoning logic of the paper are very smooth. He just read it almost in one go.
If I have to say it, the details of writing articles and using words and sentences need to be improved.
But Professor Elinor also has dignity.
Such an epoch-making article would be an insult to the author, the journal, and even himself if he were to offer only some dispensable, literary opinions!
Some things, when written by ordinary authors, are called grammatical errors, but when written by talented authors, they can only be called personal characteristics.
Only worthless academic garbage will make reviewers focus on this kind of place.
On the other hand, his mind is now full of wondering how this grid technology can be applied to solve the N-S equation, or even the numerical solution of the Euler equation.
However, according to the title and abstract of this paper, the author did not originally say that I wanted to study this part.
CMAME is not a high-end journal with an extremely high impact factor. If you can make a breakthrough in a certain direction related to numerical calculation, it is enough for publication.
What’s more, it is an achievement that may usher in a new era of computational physics.
It makes absolutely no sense to ask for more content because of this.
Roger Elinor is also a well-known figure in the field, and he wants to be ashamed.
“Alas...”
The professor let out a long sigh:
“Although I really don’t want to submit the manuscript to you like this, but...”
“This article is really perfect...”
While muttering to himself, he sat up straight again, put his hands on the keyboard, and began to write review comments.
Generally speaking, Professor Elinor has several sets of standard templates for articles on different situations, which only need to be slightly modified.
But this time, he decided to write a separate one as a sign of respect.
......
Before the review comments were finished, the phone on the table suddenly rang.
Ellinor frowned, but had to put down what he was doing temporarily and picked up the phone receiver:
"Hello, Roger Elinor, Cranfield University. ”
"Roger, it's me, Fernando." A burst of Spanish-accented English came from the other side of the phone, which made his eyes light up.
The other party was Fernando Lorenzo, whom he had just contacted via email.
As the head of Dassault’s software department in the past, he was almost naturally the first person Elinor thought of just now:
“Fernandinho, what a coincidence, I I just sent you an email ten minutes ago. If you have time..."
Under normal circumstances, it would take several hours to read such an article, so Elinor subconsciously thought that this phone call was just a coincidence.
But halfway through his words, he was interrupted by Lorenzo over there:
"I have seen your email, so I called you."
“You’ve already finished reading it? So quickly?”
“Of course I didn’t start reading it until you sent me an email.”
Lorenzo's tone was a little helpless:
"This paper was also sent to me for review, so I have been reading it this morning. I just received your email and called you back."< br>
Now Elinor also reacted.
Based on the content level of this article, there are only a few experts who are qualified to serve as reviewers.
Of course this includes Lorenzo, who was once a senior engineer in Dassault Software Department.
"Then what do you think of the idea in my email?"
After thinking about it for a while, Elinor immediately got to the point:
"If this grid generation algorithm can be used as the basis , developing a complete set of numerical calculation technology may have a decisive impact on the entire field!”
As a technician, of course he is also ambitious.
Although he is now considered successful in the UK, Elinor is still just a senior engineer after all.
There is still a long way to go before establishing a sect or at least leaving a mark in the industry.
However, the response on the other end of the phone poured cold water on him:
“Roger, this matter is not that easy.”
“ This new grid removes the structural restrictions of grid nodes and can dynamically adjust the boundaries according to model changes. It looks really beautiful.”
At this point, Lorenzo changed his subject:
“But you also have to consider that when using this algorithm to assemble an overlapping grid system, you need to find the host unit of each grid node in other sub-grids, so the amount of calculation required for the host unit search will be very huge. . ”
“This does not mention the cumbersome subsequent numerical calculation process itself because there is no topological relationship between grid units and grid nodes. In short... this is not a short time. The problem can be completely solved."
Although Lorenzo's attitude is quite authoritative, Elinor is still a little unwilling:
"If you think about it based on the current situation. How long will it take to implement this method? "
The problem of EJ200 is more troublesome. Of course, the simplest way is to directly strengthen the structure, but that will cause the performance of the entire engine to be terrible, and it will definitely not be replaced. accept.
And if you want a more clever processing method, with the current design method, you will need a lot of bench testing and even flight testing.
But according to Elinor's understanding of the so-called "European joint project", if he really delays in making a decision on the core component of the engine, then the EF2000 will be in ruins in a few years.
So the best way is to rely on heap numerical calculations to reduce test time.
He needs this technology.
“For me, this is almost equivalent to starting from scratch, and past experience is of little reference value.”
After a period of contemplation, Lorenzo finally said:
"Conservatively estimated, it may take 2-3 years to develop a roughly usable first version of the software, but the advancement of algorithms is too fast now. It’s hard to guarantee that we will face any new situation by then..."
Although it is put more euphemistically, the meaning is...
No.
“Actually, I have always had some doubts.”
After a brief pause, Lorenzo continued in a confusing tone:
“Why don’t you try to contact the author of this article?”
