Chapter 149 Sometimes, the question itself is wrong
In fact, this was the first time that Xu You took the initiative to tell Hu Shucheng about the level of his ability in a certain aspect.
After spending so much time with Xu You, Hu Shucheng certainly knew that Xu You was not a person who liked to brag.
But unless it is necessary, Xu You will not easily show his full abilities.
If Xu You said that his computer skills were no worse than those of the graduate students majoring in computer science at Ji University.
In fact, Xu You’s computer skills might be better than theirs.
Of course, Xu You had no specific estimate of the extent of his computer skills.
Xu You only knew that the several master's thesis topics he had worked on that Peng Jun had sent him were evaluated by Peng Jun as "very good."
As for the PhD thesis...
Xu You hasn't had time to do it yet, so he can't estimate his level specifically.
After Hu Shucheng told this matter to the doctoral students in the experimental group, they discussed it and finally agreed to Xu You's request.
Hu Shucheng sent more information to Xu You.
"Xu You, can you promise us that you won't leak this information to the outside world?"
"Don't worry, you should know me well. You know my style. It's relatively stable."
Hu Shucheng recalled the days he spent with Xu You in the past.
I do feel that Xu You is a very calm person.
In fact, Hu Shucheng couldn't even imagine that there was anyone who could be more calm than Xu You.
For example, during the period when the provincial physics team was training at Shengcheng University.
Xu You’s sleeping and waking times are almost fixed every day.
Xu You also maintains the good habit of doing exercises every night.
As soon as the alarm clock rings in the morning, Xu You will get up on time without even a second of delay.
In contrast, Hu Shucheng would stay in bed for ten minutes every time.
The most outrageous thing is.
Xu You even calculated his toilet time every morning very accurately.
This also left Hu Shucheng with no choice but to take advantage of Xu You's aftertaste.
"Indeed, I have never met anyone more stable than you. Well, study it when you have time. If you make any progress, you can always contact me."
Hu Shucheng did not place all his hopes on Xu You, but just found another possible channel.
After receiving more detailed information sent by Hu Shucheng.
Xu You opened the document and began to look through it.
After reading the information in the entire document.
Xu You also basically understood what this CFD software was intended to do.
First of all, the purpose of this CFD software is probably to simulate the scenario where the airflow passes through damping nets, fabrics, etc., and the pressure drops suddenly in the area that blocks the flow.
After conducting scenario analysis, theoretical modeling work is required.
The formulas that Hu Shucheng sent to Xu You for the first time were part of the theoretical modeling.
After completing the theoretical modeling work, it is necessary to design the program based on these models.
After completing these three tasks, the CFD software has basically completed the research and development design.
It seems that it only requires three steps and does not seem complicated.
But in fact, there is a lot of knowledge involved, and it is not so easy to complete.
Moreover, even after completing all these tasks.
A lot of software testing work will be needed in the future to fix some bugs to ensure the smooth operation of the software.
This is also the reason why China is stuck in the technology of CFD software.
However, although the difficulty of the whole work is extremely enormous.
But at least, now Xu You has a full understanding of the tasks and processes of the entire job.
It just so happens that Xu You’s research on the theoretical mechanism of high-temperature superconductivity is now in a new bottleneck.
It would be better to change your mind about the issue of CFD software development.
After understanding some of the main issues, Xu You dragged his suitcase to the library.
Before solving a problem, it is naturally an essential step to recharge relevant knowledge.
It is now the middle of the semester, and the library has a rich collection of books, so Xu You can borrow all kinds of books and materials to his heart's content.
When it comes to the end of the semester, universities will cram for exams, and many books are difficult to borrow.
Xu You spent a day supplementing a lot of relevant knowledge and began to have ideas about these problems.
“Let’s review the software development process first.”
To ensure that we can better solve these problems.
Xu You did not limit his attention to the formulas, but analyzed all the problems comprehensively.
Xu You knew that sometimes the question itself might be wrong.
Faced with a wrong question, even Xu You would not be able to give a correct answer.
In succession, Xu You listed out the steps that each software needed to perform.
Based on the order of these steps and the relationship between the steps, a complex iterative flowchart was made.
"Huh~ I finally figured out my thoughts."
There are dozens of steps involved in the entire flowchart.
The relationship between them is not as simple as a simple flowchart, which follows a top-down order.
There are more than a hundred arrows between each step, which is almost three times the number of all steps.
The entire flowchart makes people feel overwhelmed just by looking at it.
But Xu You has already fully understood the relationship between each step, and the whole problem has become clearer.
"Sure enough, the problem here is not as simple as just a matter of formula."
What Xu You was referring to was not any obvious errors in the theoretical modeling and programming of these doctors.
However, the relationship between each step is relatively confusing and not well clarified.
Xu You decided to follow his previous steps and optimize the theoretical modeling work before considering the equations and formulas .
"Region marking of spatial grids."
"Velocity/pressure drop characteristic parameter input."
"Instantiating porous hopping boundary conditions."
With the design of each program, Xu You's theoretical modeling work has gradually been completed.
"Yes! That's it! As long as we perfect these two equations, this part of the problem can be basically solved."
With Xu You's optimization, the previously very cumbersome and complicated equations and formulas were simplified by Xu You, leaving only the last two equations that needed to be constructed.
"Porous media momentum balance... Got it!"
Soon, Xu You found the idea and began to construct the first equation.
