Chapter 351 Am I Being Played? After Guo Ziyang opened the email, he saw that what Xu Qingzhou sent was a resource package, and then he clicked to download it. "It will take a while." Zhang Rongxian nodded, not in a hurry, or he felt it was not important. The reason why he wanted to take a look was to tell Guo Ziyang by example that projects had to be done formally, and could not be done by just bringing in a friend. "How's your progress now?" “At the moment, they are all minor issues, such as writing code that is too complicated.” Guo Ziyang roughly talked about the problems encountered by the group. Boom~boom~ At this moment, there was a knock on the door. An old man stood at the door, "Old Zhang, busy." "Not busy." Zhang Rongxuan shook his head and said with a smile: "Xiao Guo, wait for me for a moment."
"Director." Guo Ziyang immediately stood up and greeted the visitor, while packing up his computer and making room for him. Zhu Jichuan nodded to Guo Ziyang, sat down, and said to Zhang Rongxuan with a smile, "You just came back yesterday, and you're already in the office today. Don't you even want to take a break?" "Can't sit still." Zhang Rongxuan shook his head, smiled and said, "After going out, I realized that the computer industry is developing too fast. If we old guys don't work harder, we will be left behind by the young people." "Yes, we are all old." Zhu Jichuan also sighed. "You are such a busy man, why are you suddenly visiting me? Is there something wrong?" "Hey, yes, we are working on a CMS (content management system) project with Nanjing University. The academy has discussed this and would like to invite you to take charge." "Where's CMS Lao Zheng?" Zhu Jichuan smiled bitterly, sighed deeply, and said, "Old Zheng is in the hospital." "Hospitalized? He was in good health, why was he hospitalized?" "Life is unpredictable. I was diagnosed with liver cancer some time ago." Guo Ziyang sat there obediently, listening to the two people chatting. After two years of training, he didn't feel as cramped as before when staying here alone. After chatting for a while, Zhang Rongxuan agreed that Zhu Jichuan's business was done, and looked at Guo Ziyang on the side, "Student Guo Ziyang, I heard from Teacher Li from the Student Affairs Department that you will not be the director of the External Relations Department next semester?" "Yes, the term has changed, and I happened to be working on a project on elastic contact simulation with a few friends." "Elastomer contact simulation? That's very difficult." A flash of surprise flashed across Zhu Jichuan's eyes. This was not just difficult, it was hellish difficulty for an undergraduate. Just the IPC in it is not something that an undergraduate can handle. "We just tinkered with it for fun." Guo Ziyang scratched his head. Zhu Jichuan praised with a smile: "Don't belittle yourself. In the rapidly changing field of computer science, it is very rare to face difficulties and challenge difficult things."
Guo Ziyang still felt a little flattered and smiled shyly in response. At the same time, the resource package was downloaded to his computer. In addition to the model, there was also a document in the resource package. He clicked on the first one to run the model. As a result, complex and orderly geometric figures and data flows flashed on the screen. Guo Ziyang was stunned for a moment, with only one thought in his mind: "What the hell, is my computer infected with a virus?" Across from him, Zhang Rongxuan took a sip of tea and noticed that Guo Ziyang was staring blankly at the screen. He couldn't help but remind him, "Ziyang?" Guo Ziyang was a little embarrassed, "Professor, the model has been downloaded. Do you want to take a look first?" "Then let's take a look at the IPC model made with the help of his friend, but I heard that there was a problem." Zhang Rongxian turned to Zhu Jichuan and said. Zhu Jichuan nodded, not surprised, and said with a smile: "The IPC model requires a lot of calculations, especially when dealing with large-scale deformations and complex multi-body contact problems. It's very difficult." "Yes, I plan to borrow someone from the School of Mathematics for this kid. There is a lot of research on elastic body contact simulation." Zhang Rongxian's voice suddenly stopped, he stared at the screen with a frown, something was wrong, why was it so smooth? "This..." Zhu Jichuan was also stunned, with a strange expression. He moved his chair so that he and Zhang Rongxian could watch it together. On this side, Zhang Rongxian had already taken out his reading glasses and put them on. Guo Ziyang stood behind the two of them and tactfully did not disturb them. Zhang Rongxian and Zhu Jichuan stared at the screen, their expressions gradually becoming serious. In the center of the screen, a three-dimensional IPC model slowly rotates, and every detail is so exquisite that it is breathtaking. Zhang Rongxuan's tone was full of amazement: "The treatment of the contact area is particularly excellent. When the two elastic bodies touch lightly, there is no trace of penetration. There is only a perfectly fitted contact surface and a contact stress distribution map that gradually emerges during the loading process." Zhu Jichuan nodded and said in a deep voice: "Yes, it's very good, even perfect." “Besides, it runs too fast!” “An obstacle-based augmented Lagrangian iterative model is also added.” "Yes, yes, yes. Not only that, he seems to have also innovated the storage method of ultra-large-scale sparse matrices!" The two bosses were looking at the IPC model carefully and sighing repeatedly. Guo Ziyang, who was standing next to them, was also surprised and puzzled. Is this what Xu Qingzhou meant by “You’d better be mentally prepared”? Hey~ Xu Qingzhou sent several messages in succession. He came back to his senses and took out his cell phone. Xu Qingzhou: "Have you finished reading it? Is it different from what you asked for?" Xu Qingzhou: "I'm not saying that the original IPC model was too weak. This model has achieved a nearly 128-fold improvement in computing efficiency based on IPC, and it has also eliminated matrix decomposition, reducing memory overhead from more than 8G to only G, and can also solve rigid pathological problems." Xu Qingzhou: "To know how horrible it is, you can read the paper yourself. I have sorted it out." Guo Ziyang understood a little. It was obvious that I was being played. 10 minutes passed. Zhang Rongxuan turned to look at Guo Ziyang, his brows knitted together: "Ziyang, your friend."
Is this professional? It's obviously quite professional. My level in mathematics is definitely higher than theirs. "Xu Qingzhou." Guo Ziyang did not hide it. He did not mention the name before because he thought he could not tarnish Xu Qingzhou's reputation, lest others think he was just a show-off. "Xu Qingzhou? Sounds familiar." Zhang Rongxian couldn't remember who he was for a moment. Zhu Jichuan reacted faster, his eyes lit up, and he said in a deep voice: "Are you talking about Xu Qingzhou from the School of Mathematics of Peking University?" "Yes, he and I were classmates in high school, so I wanted to ask him for a favor." (End of this chapter)
