Before returning to the college entrance examination, I became popular in the science circle

Chapter 113 Computing Materials
"Let's not gossip, let's get to the point, Wu Tong, I heard from Lao Pan that you made a mathematical model, and it was a mule or a horse that came out for a walk. Let me see the feasibility first, and I will let Cheng Xu take you to identify the guy later." !” Cheng Lao ordered straightforwardly,

Wu Tong went back yesterday and repeated a manuscript. Now that Cheng Lao pointed it out, she took it out of her backpack and handed it over with both hands. "Cheng Lao, please advise!"

She is still just getting started in materials science, so it's a great thing that such a big boss is willing to give her some advice.Thank you, old man, for being a good teacher.

From the very beginning, as soon as you see it, it is full of mathematical formulas, twisted and twisted, Cheng Huanan can't help but have a toothache for a while, the typical style of mathematics, the things made by people who engage in mathematics are really annoying, if his old man can learn mathematics Okay, there is no need to lower your head every time to beg Lao Pantou!

However, since he opened his mouth, Cheng Huanan still bit the bullet and read on. After so many years of accumulation, he said that he was not good at mathematics, but compared with those who are professional in mathematics, he still has a foundation.

In particular, these books had some transformations in materials science, and he could still understand the logic.

As the page progressed, Cheng Huanan's face couldn't help but become more serious. Those sensitive data looked particularly familiar to him.

"Raptor F-22 model layout data?" His first reaction was, did Lao Pan lose his nerve?How to give such confidential project information to a child?
"I had some feelings for a while, and did some derivation. I deduced some key data. The dean has asked me to sign a confidentiality agreement!" Wu Tong wanted to scratch her head. When she deduced, she really didn't expect that confidentiality regulations would be designed. .

Did you deduce other people's secret information on a whim?This was the shock that came from the teachers and students of Cheng Huanan.

Cheng Huanan felt the most. Why didn't he know that the Raptor's data could be deduced so easily?Chen Xiagang, the former elder Pan who assisted Xifei, spent four months pushing out the Poincaré airway. The excitement of the two old men is still vivid in my mind.

Compared with Wu Tong's random stuff, can those two complacent old things hit the south wall?No wonder that cunning old man Pan Wenhua was so willing to sacrifice his life and bow to him. With such a big treasure, he must do his best to protect it!

Hmm... maybe there is some room for development, but I would like to thank Lao Pan for sending such a talented person to him.Chengxu and the others still lack a junior sister, and he also lacks a close disciple!

Cheng Huanan read back more seriously. He saw the derivation of the material at the back. Although it was a bit immature, the logical angle was novel and correct. Is it a feasible direction?

A self-taught kid who only sat in on a few material classes could make such a design. Coupled with this kid's top-notch math skills and photographic memory, this talent made him a close disciple. He was determined!

A rare smile flashed across his eyes, and Cheng Huanan pointed more naturally, "Chengxu, give Wu Tong some basic knowledge, take Wu Tong to identify the instrument, and then do a calculation simulation!"

The foundation must be laid from the basics, starting now. He is ready to compete with Shuyuan for people.

"Wu Tong, come with me here. Look, this is our scanning electron microscope, Thermofisher1050. This is Leica's metallographic microscope. This is our stretching machine... This room is used for reactions. Furnace..., this is the computational simulation studio..."

"Computational materials science is emerging in recent years. In today's materials research, it is used as an auxiliary means. Through experimental data, mathematical models are established, and then simulated by computers. Through various repeated simulations, the mathematical models are revised, and based on the revised Use mathematical models to design manufacturing processes and create material entities for testing..." Ruan Chengxu Hexu introduced the computational materials science involved in simulation to Wu Tong in detail, which is his minor direction.

"Or directly carry out simulation calculations based on some specific materials and reaction mechanisms to obtain specific data models, and then design the proportion of materials that meet the target through experiments to prepare, which can be regarded as a kind of predictive research.

It’s just that at present, computational materials science can only make approximate estimates at best. Material experiments can cause earth-shaking differences for some inexplicable reasons. Many times, the calculated results are very different from the final results..."

"At present, we still lack a truly predictive computational materials theory as a basis for research!" Ruan Chengxu lamented with regret.

When he first came into contact with materials, he was still very ambitious, looking forward to preparing various super materials to help build the country, punching old M, kicking European and African criminals, and leaving his name in history.

When I actually entered the door, I realized that the biochemical ring material and the four major sinkholes lived up to their reputation.He, a 26-year-old good young man, is still buried in a pit and has never seen the light of day, and his future is still far away.

"This subject has relatively high requirements for mathematics and requires the cooperation of computers. This is just perfect for you, Wu Tong!" With Wu Tong's mathematical skills, it will really be like a fish in water to turn to calculation materials.Those mathematical problems that seemed complicated and awkward to them might not be a problem in Wu Tong's hands.

With Wu Tong's foundation as the material, and his teacher's passion for talent, I'm afraid he has already booked their junior sister.Therefore, Ruan Chengxu explained with great care.

"Come on, Wu Tong, let me teach you how to import data to build a model!" Ruan Chengxu demonstrated to Wu Tong using the laboratory computer. The laboratory computer is relatively well equipped, far beyond what ordinary computers on the market can compare with. In terms of performance, only supercomputing can pull it down far.

Wu Tong is no stranger to computational materials science. It is a section that she is more interested in after coming into contact with materials science.The mathematical model she is currently building is based on a certain foundation in computational materials science.It's just that she transformed more thoroughly.

After carefully learning the operating methods from Ruan Chengxu, Wu Tong felt that it was necessary for her to add some computer-related learning, various computer languages, software programming, professional software for computational materials science VASP, Phonopy, and even detailed chemistry and materials science. Content must be put on the agenda.

After gaining some proficiency, Wu Tong began to input her calculation model and various data line by line. Her material model was based on creep resistance, oxidation resistance, high enough strength, and stability. Deduced on the basis of extremely strong tolerance.

Compared with ordinary workers, Wu Tong's deduction has an absolute direction to rely on, and it is the best trial and error tool.The periodic table of elements is listed, and when various existing element symbols pass in her mind, the elements that meet her requirements in the right direction are naturally selected by her first choice, and thus establish a material that is biased towards aviation and has better performance. Titanium alloy model.
