The Courtyard House: Xu Damao's Aunt is the Queen of Women

Professor Qian took over the conversation and said seriously, "The three core tasks we are currently advancing are the calculations for the hydrogen bomb principle, the hypersonic aerodynamics calculations for intercontinental ballistic missiles, and the calculations for the orbit and reentry heat protection of recoverable satellites. All three involve extremely large-scale coupled equation calculations."

He tapped the document lightly and continued, "The only 104 electronic computer in the country can only perform 10,000 calculations per second. Just to calculate one set of basic data, it takes more than half a month to run continuously."

"There are also frequent issues with iteration divergence and data distortion, making it impossible to keep up with the project schedule."

"The rest relies entirely on hand-cranked calculators, abacuses, and slide rules. Dozens of researchers work in three shifts, day and night, calculating for months, but they may not be able to produce a set of accurate and usable results, and the error is still huge. If this continues, the entire project will be delayed indefinitely."

Liu Hao didn't interrupt, listening quietly as he casually flipped open the document in front of him, his eyes quickly scanning the pages.

What comes into view is a densely packed system of multidimensional nonlinear partial differential equations, coupled with physical field parameters, material property constants, boundary constraints, and thousands of variables intertwined, making it extremely complex.

Even with his super-powerful computing ability exploiting a system bug, he could still clearly perceive the difficulty of these calculations.

Professor Guo pointed to the first document and explained the core calculation method in detail.

"Let's look at the first item, which is the coupled calculation of hydrogen bomb radiation hydrodynamics and neutron transport. There were no external reference materials, and we relied entirely on our own exploration. The four physical fields of radiation transport, fusion material compression, neutron multiplication, and energy deposition are strongly coupled, and the equations are extremely complex."

"We can build the computational model and list all the equations, but we just can't achieve stable convergence. The calculation will crash halfway through. The R&D team has been working on this for more than three months without any breakthrough."

Liu Hao nodded slightly, his gaze sweeping over a set of core equations, his brain beginning to quickly organize the calculation logic.

Various parameters and variables are automatically categorized, and the coupling relationships gradually become clear.

"The difficulty lies in solving multiple fields simultaneously. Conventional calculation methods cannot take into account the correlation between various variables, leading to iterative divergence. As long as the decoupling logic is optimized, and layered calculation is performed and then synchronous back-substitution is performed, the convergence problem can be solved."

These words pinpointed the crux of the problem. There was no surprise in Teacher Qian's or Teacher Guo's eyes, but rather an unwavering certainty.

"We also tried decoupling, but the computational load was too huge. The sub-equations after the layering were still difficult to overcome. They were nested layer by layer, and we didn't know where to start."

Professor Guo's words carried a hint of helplessness. This is the biggest dilemma faced by all researchers today. It's not that they don't understand the principles, but that their computing power is simply not up to par.

"I know."

Liu Hao responded and picked up his pen.

"I can directly perform layered parallel computing, skip the redundant iterative steps, calculate the core control solution first, and then deduce the various parameters in reverse, which can ensure both speed and accuracy."

After saying that, Liu Hao began to do calculations.

There was no draft, no pause, and no corrections.

The pen tip glides swiftly across the paper, making a soft rustling sound. The handwriting is neat and clear, and the steps are concise and refined. Each step directly addresses the core of the calculation, skipping the tedious process of repeated verification required in ordinary calculations.

He first tackled the calculation of hydrogen bomb radiation fluid coupling, quickly sketching out the core matrix framework and decomposing the strongly coupled physical fields into layers.

First, the core equations of radiation transport were solved. With the pen constantly moving, a series of precise values ​​and rigorous derivations appeared on the paper. In just ten minutes, core data such as radiation energy flow distribution and fusion compression ratio were obtained.

Teacher Guo stared intently at the calculation process and results on the paper, occasionally comparing them with the calculation drafts she carried with her, and sometimes quietly asking questions about a calculation node.

As Liu Hao wrote, he answered, and the calculation logic and parameter selection he provided were all in perfect accordance with scientific research standards, and were even more concise and efficient than the optimal solution they had explored.

"Did you directly take the optimal value for the neutron multiplication factor here?"

"It took us a full twenty days to verify this value, and we revised it seven times."

Guo Yonghuai pointed to a set of data and asked softly.

"The coupling range of this variable is fixed. By eliminating invalid disturbance terms, the optimal value can be locked directly without repeated iterations and verifications."

Liu Hao didn't even look up, and his writing speed wasn't affected in the slightest.

Teacher Qian sat quietly to the side, watching Liu Hao's calculations, occasionally asking questions about engineering applications.

For example, Liu Hao gave clear answers to questions such as whether the calculation results were suitable for existing materials and whether the numerical accuracy met the experimental requirements.

Not only were the theoretical values ​​calculated, but the correction values ​​and error ranges for engineering applications were also marked, perfectly matching the actual R&D needs.

After completing the calculations related to the hydrogen bomb, Liu Hao seamlessly transitioned to calculating the hypersonic aerodynamics and reentry thermal protection of intercontinental ballistic missiles.

This task involves multiple coupled calculations, including hypersonic flow fields, real gas effects, aerodynamic heating, material ablation, and structural stress, resulting in more variables and more complex logic.

But in Liu Hao's hands, there was still no lag whatsoever.

He quickly sorted out the flow field control equations, solved key data such as shock wave location, aerodynamic drag coefficient, and peak heat flux, and accurately calculated the ablation rate, thickness requirements, and stress tolerance limit of the heat-resistant material for the high-temperature ablation problem during reentry into the atmosphere. Every set of data was accurate and the derivation process was rigorous and meticulous.

"We've always struggled to accurately calculate the deviation in turbulence during missile reentry. You've provided a fixed correction range; can that guarantee stability throughout the entire process?"

Teacher Qian looked at the results on the paper and asked softly.

This is a core pain point in missile development; even a slight deviation can lead to test failure.

"The range of variables for turbulent disturbances is limited. By combining the flight trajectory and atmospheric parameters, the correction range can be directly locked without significant fluctuations. This value can be fully used for warhead design."

Liu Hao responded softly, and with a stroke of his pen, he marked the relevant parameters more clearly.

He Xiaomeng and Ye Xi watched as Liu Hao effortlessly overcame one difficult problem after another, their eyes filled with awe.

Even knowing how amazing Liu Hao's calculation ability is, it still feels terrifying, horrifying, and unbelievable!

Is this even human?

It's important to understand that the bottleneck in scientific research challenges such as hydrogen bombs and intercontinental ballistic missiles isn't theory or materials, but rather the inability to perform the calculations.

Strongly coupled equations—there's no one in the whole country, no machine, that can calculate convergence.

Liu Hao, however, was able to calculate steadily, accurately, and completely, and he did so effortlessly!

Ye Xi and He Xiaomeng finally understood why their in-laws wouldn't let Liu Hao go to the Malan training base.

He cannot be publicly acknowledged, cannot be included in the government system, and cannot leave his name!
