The abaqus results are dissected to show why the chaotic lines are occurring

I personally have the following points for your reference:

1. Reasons. Abaqus is one of the most powerful software for nonlinear calculations and the most powerful engineering simulation software at present, and it has a wide range of users around the world, just like Ansys, the linear analysis software. In fact, ANSYS (linear) software entered China earlier than ABAQUS (nonlinear) software, and ANSYS is committed to the use of computer resources and user interfaces in the field of linear analysis.

Development and other aspects have made great contributions. Abaqus software.

It is dedicated to more complex and in-depth engineering problems, and its powerful nonlinear analysis capabilities have been widely recognized by the high-end user base of design and research. Personally, I think it's strange that when users installed these two software, there weren't too many "error prompts" and harsh permission restrictions, and in the past two or three years, every time they install these software, there is always a lot of trouble (personal feeling), especially abaqus, I don't know if it's because of "copyright protection" or industry monopoly that causes a lot of trouble and "frequent errors" during installation.

2. Phenomenon. This situation you encounter is one of the problems encountered by many netizens installing the software. Based on the limited information you provide, the error message "invaiid iicense server(s)**error:" is displayed

please entnr exactly one or three license servers.I only understand the error of "invaiid iicense server(s)*: Please enter exactly one or three license servers.

Seems to be a response to the server (or uploader?) ) qualifications or identity, and more like the lack of certification or license for the software itself, etc.

3. Method. First, if your software is confirmed to be genuine, please double-check whether you are required to enter the serial number, registration code or password of the software during the installation process, then enter the relevant information provided in the manual or box. Second, if the software is installed, then you can reinstall it, or try to get the abaqus software with the installation information when you want to install it.

Third, if you want or can, consider the "green" or "cracked" version, which is also a last resort. By the way, the "green" or "cracked" version is sometimes not as scary as some netizens say are "ill-intentioned", implanted "Trojans" and spread viruses.

Those are deformed meshes.

This is all because you are using a section that happens to be near the faces of a row of elements.

The section passes through the faces of a set of elements. These element faces are basically perpendicular to the section, but not completely perpendicular. Hence the oblique intersection lines.

The direction of the intersecting lines is most likely related to the local rotation of your beam, as well as the Burson effect.

Probably it's a display issue, or you happened to cut the face at this point.

Problems with your graphics card and see if you have the same problem with a different computer.

It's okay to show only part boundaries without meshes.

But the partition boundary doesn't seem to be displayed.

If the abaqus is installed, a splash screen appears.

Or open multiple windows, or a white screen directly in the middle of the window, etc., this is not a problem with the graphics card, according to my years of experience.

There are two main problems with this:

1.Check whether the license is installed correctly;

2.Check the system compatibility problem, some abaqus versions are not compatible with 32-bit systems, several colleagues have this kind of problem this year, I reinstalled the 64-bit system after it was fine. It is recommended that you install a 64-bit system, the memory is more than 4G, if it is a 32-bit system, the 4G memory only shows less than 3G, and when you do power calculations in the future, 2G memory can not be calculated, you can only open the calculation results.

Update the graphics card driver again.

Tools-View-Slices-Manager (for all modules).

It can also be this icon.

In the visualization module, icons.

There is a cut. The force of the component can be cut, and it can also be cut in the assembly.

On the desired result graph option, generate a path or a node, the abscissa can be defined by yourself, the ordinate can also be used, and then you can extract the curve you need in the data option.

Can you describe your problem in detail?

Open "Results" and "Analysis Steps", and in the pop-up dialog box, you will see the two analysis steps set before, Select, Apply, and come out.

If the first step is a linear perturbation, its calculation does not affect the time.

Isn't there a step you give negtive?

Is it that the type of analysis step is wrong?

I guess what you're trying to ask about is this function: the third to last in the second column of the menu bar under the part module, and press and hold to open the function of the fourth button in the small black triangle in the lower right corner "remove redundant entities".

Have you solved this question?

It will affect meshing, and if you delete in assembly, you can only select the instance to which the line depends. Is there an answer?

As far as I know, this kind of line can't be deleted.
