There are a lot of computer software for mechanical majors, but not all of them have to be learned!Because the principles of modeling software are the same, learning one can quickly learn others. The following is the computer software to be learned in most schools, for the reference of mechanical engineering students only. 1.Learn mechanical design: understand mechanical drawings, and learn hand-drawn and machine-drawn paper, and learn AutoCAD or CAXA software for machine drawing. 2.Learn 3D design: learn CAD 3D modeling software, 3D drawing SOLIDWORKS software, CATIA Alias software for the automotive industry, mold design Siemens NX software. 3.Learning and analysis: Use software to simulate the force of the product in different environments, improve product design, and commonly use ANSYS Workbench, COMSOL, and Abaqus finite element analysis software. 4.Learn mechanical principles: engineering must learn MATLAB software, mechanical motion analysis, fault diagnosis, etc., and use MATLAB to complete the homework of mechanical principles courses. 5.Learn mechanical manufacturing: use UG SW software to generate CNC machine tool processing programs, transform the designed products into actual manufacturable objects, and understand the manufacturing and processing of products. 6.Learn embedded development: use C language programming in Keil software, and burn the program into a single-chip microcomputer to control hardware equipment, which is suitable for mechatronic direction. 7.Learn mechanical automation: learn robot programming, mechanical motion control, commonly used MATLAB, C language, Python language. 
There are many development directions of mechanical majors, such as pure machinery, intelligent manufacturing, vehicle material control, over-control, etc., because the situation of each school is different, so the computer software used is also different. You can send the views of this article to the seniors for their opinions, or send it to the roommates to discuss and make a decision according to the actual situation. The following are the official computer requirements for the software:
Most mechanical software is recommended to use a graphics card, and a notebook with a graphics card is called a mobile workstation. Which graphics card is the best workstation to choose?3D modeling itself does not have very high requirements for the graphics card, and only when the model is rendered into ** or animation, it has high requirements for the graphics card. Small and medium-sized assemblies: 10,000 parts for a single assembly, T600 or A500 graphics card is recommended, and the video memory is 4GB, which is suitable for mechanical students and professional designers. The number of parts in a single assembly of large assemblies is 10,000, and **A1000 or RTX2000ADA graphics cards are recommended, with 6GB or 8GB of video memory. Choose a graphics card according to the above suggestions, and the rotation and zooming in and out during the 3D modeling process can be very smooth. If you need to render assembly animations, you can refer to the ** below to choose a more powerful graphics card.
Data**: NVIDIA official documentation).
The more CUDA cores, the better: The graphics card can speed up rendering** or assembly animations, the rendering process involves a lot of computational work, CUDA cores are like a large group of small workers who work hard to calculate, the more CUDA there are, the faster the rendering. (For example, if you use the CPU to render, you will have to wait 30 minutes, but you will only have to wait 2 minutes to render with the graphics card.) The larger the memory, the better: mechanical 3D modeling will have a lot of complex assemblies and parts, and these model data need to be temporarily stored in the video memory, the more complex the model, the more the video memory will be eaten, and if the video memory is not enough, the modeling software will be stuck or even stuck. Do I have to use a professional graphics card for mechanical modeling?Does the gaming graphics card work?Gaming graphics cards can actually be used, but professional graphics graphics cards are highly recommended, and there are the following benefits in SOLIDWORKS software:1Support for realview function RealView is a pre-rendering feature that provides a photorealistic image of the model without the need for rendering. 
This feature can only be enabled on professional graphics cards, not on gaming graphics cards. (In fact, the game graphics card can also exploit the loophole to forcibly open the realview small gold ball, but the compatibility is not good, and the rendered parts may also have color errors) 2Support FSAA anti-aliasing (full-screen anti-aliasing) FSAA stands for "full-scene anti-aliasing", and enabling anti-aliasing in SW can reduce the jagged edges of the model and improve smoothness. 
This feature can only be enabled on professional graphics cards, not on gaming graphics cards. 3.Finite element analysis accelerates high-end professional graphics cards that support ANSYS compute acceleration, but gaming graphics cards do not, please refer to the official NVIDIA documentation if necessary. Students in school do finite element analysis and use CPU calculations. 4.Metaphysical ordinary game graphics cards with poor compatibility run mechanical CAD software SOLIDWORKS, UG, CATIA, PROE, may be stuck due to driver problems, display errors, etc., and the compatibility of professional graphics graphics cards is better. How to choose a notebook CPU?The CPU and the graphics card are equally important, it is involved in all aspects such as mechanical modeling, ** analysis, rendering, etc., and the CPU performance is not enough for the computer to get stuck. But in the field of mobile workstations, as long as you choose a graphics card according to the suggestions above, its CPU will often not be badly matched, so put it in second place. Mid-range: R7-6800H, i7-12700H
High-end: i7-13700h, i9-13900h
Flagship: i9-13900HX, i9-13980HX
How to see whether the CPU performance is strong or not, refer to the notebook CPU performance ranking:
December 2023: Laptop CPU ladder chart, computer processor performance ranking Ultra5 7 memory and hard disk: All workstations recommended in this article support memory expansion and hard disk expansion, and all of them support solid-state drive expansion. In terms of running memory, college students generally use 16G is enough, and if it is not enough in the future, it can be expanded, and the company recommends that it not be less than 32G. Each additional 1TB SSD costs about 300 yuanEach additional 16GB of running memory (replacement memory) costs about 400 yuan. What brand to choose: In the field of mobile workstations, because the market size is limited, there are only Lenovo, HP, and Dell in China, and there are not many models to choose from. Buy online or offline: It is only recommended to buy online, and the biggest advantage of Jingdong's self-operation is: as long as you do not connect to the Internet when you inspect the machine, you can return the product after unpacking. Other platforms can't go back as long as they unpack. According to Moore's Law, every 18 months the performance of a new computer doubles, and every three months there is a better computer.
