How to use the ansys+allsel command.

Thank you very much for your question. ANSYS is a finite element analysis software widely used in the engineering field, and Allsel is one of the most important commands. I'm going to give you a detailed look at the usage of the allsel command below.

The allsel command is a single hooded selection command in ANSYS that selects all entities in the model. The syntax format of the allsel command is as follows: the allselallsel command is to select all entities in the model, so that the entire model can be manipulated.

The allsel command is typically used in the following cases:1Before proceeding, all entities need to be selected.

2.When performing certain operations, you need to perform operations on the entire model, such as meshing, solving, and so on. The use of the allsel command is very simple, just type allsel in the command window of ansys and press enter.

When you enter the Allsel command, ANSYS automatically selects all entities in the model. It should be noted that the allsel command can only select entities, not nodes and cells. If you need to select nodes and single-excitation elements, you need to use other selection commands, such as the nsel and esel commands.

In summary, the Allsel command is a very important command in ANSYS that can help engineers quickly select all entities in the model for subsequent operations. If you're having trouble with Ansys, feel free to ask me and I'll do my best to help you.

No, no error file and no process file, how can we analyze what you** did wrong? Posting ** is the most convenient way to illustrate the problem. Visual inspection of the result plot:

Either there is a problem with the data, and the result of the no-load calculation is to apply an overall downward gravitational acceleration to the entire model. Then if you confirm that there is no problem with your addition, it is a data problem. Do the math, according to the data you give, whether the left part of the fulcrum is heavier, or the right part is heavier.

ANSYS software is a large-scale, general-purpose finite element analysis software that integrates structure, fluid, electric field, magnetic field and acoustic field analysis. Developed by ANSYS, one of the world's largest finite element analysis software companies. It can interface with most CAD software to achieve data sharing and exchange, such as Pro Engineer, Nastran, Alogor, I Deas, AutoCAD, etc., and is one of the advanced CAE tools in modern product design.

Personally, I think:

You can start with the book "Finite Element Analysis Self-study Manual (including 2 disks)" (edited by Deng Fanping 2007.01 People's Posts and Telecommunications Press), no matter which version you have, as long as it is not less than, this book is applicable, and the book explains in detail, this book focuses on the basic knowledge of finite element analysis using ANSYS, including the basic process of ANSYS finite element analysis, solid modeling, meshing, loading and solving, general post-processing, Time history post-processing, advanced Ansys operations, and more. It's helpful to get started with ANSYS.

After that, you can learn the APDL language, the general master will learn this, it is recommended that you use the "Ansys Parametric Programming and Command Manual" (published by the Machinery Industry Press), which has a more detailed explanation of APDL.

In addition, there is a workbench, which integrates 3D modeling, meshing, post-processing and other functions, and also integrates fluid analysis, electromagnetic field analysis and other functions, and the interface is friendly, much better than the mechanical Ansys interface, this can refer to the "Ansys Workbench 12 Basic Tutorial and Detailed Example Explanation" (author Pu Guanggai), I personally think it's okay.
