I was performing a static structural beam deflection simulation in ANSYS 2022 R1 (Student version). It consists of a simple rectangular cross-section beam subjected to a uniformly distributed load and 2 edge boundary conditions. I created its geometry in the design modeller and then moved onto the model section. I meshed it, applied loads and boundary conditions and solved it. Upon solving it, if I click on, let's say "Directional deformation", to observe the results. After about 5 seconds, ANSYS Mechanical automatically shuts down itself leaving behind the project schematic window. If I click on "Model" again, it opens ANSYS Mechanical briefly for about 2 seconds before shutting down again after displaying an error. I can't even visualize my results, because it keeps shutting down whenever I click on any of the options on the left side in ANSYS mechanical, after solving.

PFA the error displayed.

I don't know how to resolve this. Please help me out as soon as possible!

[George Karnos]

Under the %TEMP%\WorkbenchLogs directory you should see logs from the session.
Can you check those and post any errors you may see?
Please post the error, not the file as we are not permitted to open files.
Thank You

[Rosterzr]

Could you give a step by step guide on what I should do? I am confused.

[Rosterzr]

Please. I will be obliged if I could get some possible solution for this issue.

I have a similar issue and my logfile shows the following:

Thank you beforehand for helping me out.

Please refer to the following discussions:
Workbench Extensions Manager "Root element is missing" ÔÇö Ansys Learning Forum
Piezo and MEMS Extension install error ÔÇö Ansys Learning Forum
You can also search for "Root element is missing". This will bring up more discussions.

[tdevlieger]

Thank you for your reaction. However, I tried both solutions from the link but I keep getting the following error:
Do you have any idea how I could resolve this issue?
Sincerely
Tim

[tdevlieger]

I still have the following error, could you help me out with this, it keeps shutting down the mechanical.

Sincerely
Tim de Vlieger

[tdevlieger]

I have this exact same issue, could someone help me out please?

Thanks a lot beforehand

[George Karnos]

Try the following:
Make sure no Ansys programs are running
Go to :
%APPDATA%\
(This should take you to a directory: C:\Users\\AppData\Roaming\)
You should see a directory named: Ansys
rename that directory to: Ansys.old
Now try to run.

[tdevlieger]

This works, thank you, you really helped me out with this. Had been struggling with this for 2 weeks now.
You're a legend!

Thanks again!!!

[tdevlieger]

Okay this worked for 1 day and now I get the similar message again. Once the message occurs in a certain file, it keeps coming back there and I need to restart my entire process of making an analysis.
Is there a permanent solution for this problem? Thank you beforehand.

Below I provided the error message I get:

[George Karnos]

Does it start again if you remove the %AppData\Ansys directory?
Do you have Virus protection installed?
What happens if you disable it and any firewall as a test?
What happens if you start Workbench in the following way:
right-click on Workbench 2022 R1 and choose: more->run as administrator

[Fuergrissa]

I have the same issue, Ansys must be run on a VM by university policy, I have no ability to adjust firewall or virus protection. I did rename the ansys directory as described but it did not change the resulting error. All of my recent projects have been corrupted this way, so I cannot move forward until I get a resolution.

I had McAfee running on my laptop but I removed this. Further I followed your instructions and now it works again.
Lets hope it is a permanent solution this time. Thanks for coming up with solutions so quick!

I'm having same issue with my Ansys student 2022 R2. It would be great if anyone tell me how to solve this issue. I've been trying to clear log files, reinstall Ansys. But nothing really worked.

[Matt Chase]

Has anyone founda solution to this issue?

 

[Raihan Lutfianto]

Not yet found any solutions to this

[Amaranth]

Hello All,

I am getting same error as well..

here is how it looks:

 

I am getting the same error too. I tried renaming the previous ansys file to ansys.old and the reopened the workbench and loaded the file. I still get same error. let me know if I need to do anything else ?

I tried renaming the file as .old as well and it still does not run.

 

 

Any help is appreciated

 

[Azhar Hajdarevic]

Same problem here I tried all the solutiouns no help to fix it :( 18.10.2023 btw I see the first post is from 21.3.2022 

[Azem K]

If someone have this problem, lets try this. In my case its working.

1. Run as Administrator Workbench
2. Press File > Save in folder whose come from Ansys, just give a name to file.
3. Try Simulation and Analysis
4. When its all okay than create Folder(random name), copy files  “exercise one” and paste it in.
