My first post here!   I have just installed R19.0 and have trouble meshing a simple beam (or any other object I have modeled). Everything else seems to work.       When meshing I get the following errormessage:   The mesh generation did not complete due to poor quality elements or incorrect input. Please try meshing with another mesh method or different mesh options.     Instead of explaining what I have done in words, I have put up a video showing my steps. Hopefully someone can tell me what I am doing wrong!

Have you tried doing as error says- with smaller mesh and different methods, for instance proximity instead of curvature?

[vganore]

Can you try setting up relevance to 100 instead of zero. Also use fine mesh option. See if it works out. 

[morsan]

Thanks for tips on my mesh issues.

 

As I am pretty unfamiliar to Ansys, I had just tried the default mesh setting (adaptive size method). Besides Adaptive, I have now tried all the other methods, but the error remains. I have also tried to set relevance to both -100 and +100, and relevance center to Coarse, Medium and Fine. When using the Proximity method, I have tried to adjust Max Face Size with no luck. I have also tried to ignore mesh errors (Check Mesh Quality setting).

 

It would be nice if anyone could share a simple beam model that work on their computer to rule out that my settings are the problem.

Or maybe just reinstall ansys?

[morsan]

I have reinstalled the software (cleaned up every trace I could find of the previous installation before reinstallation), but sadly, the result remain the same. On the same pc, I have an installation of Ansys Student Discovery Live that works without any issues.

Hi all

I have the same issue as morsan. 

"The mesh generation did not complete due to poor quality elements or incorrect input. Please try meshing with another mesh method or different mesh options"

I have tried to reinstall, update drivers, change geometry, mesh size, type... and now I have run out of options.

Has anybody solved the problem? Any help would be much appreciated!

Hi, Are you also using 19.0?

I just tried everything the same way in 19.0 as well and had no problems...

P.S: In the future, please start a new discussion. Older posts or long threaded posts tend to get less attention. You can always link it to the older post if you want to do so.

Hello,

Could you please try and reinstall the prerequisites for us? The default program to run is:

C:program filesansys incansys studentv190productconfig.exe

Make sure you Run as Administrator. Click on Install Required Prerequisites. Let us know if that fixes it for you.

Thank you.

[Sandeep Medikonda]

Also, if it doesn't work. Can you post an image of all the details included under Meshing?

Regards,

Sandeep

Hi,

I am having the same problem with Ansys 19.1. I tried to reinstall the prerequisites as DavidYakinian suggested but the problem persists. I cannot create the mesh even with a very simple geometry.

 

 

Thank you.

 

[Sandeep Medikonda]

Can you upload it to Youtube and provide the link here? We are unable to access the drive location.

Can you please post some snapshots of all the Details of "Mesh"? Expand everything, Sizing, Quality, Inflation, Advanced and Statistics?

This is a very rare problem and it is hard to debug as we are unable to reproduce it, If you are at a university have you tried on a different computer or even a friends computer (please make sure you use the same ANSYS download)? This is not a fix but might get you going and eliminate any problems with the installation file.

Lastly, can you please provide complete details of your machine, configuration etc?

Regards,

Sandeep.

[luizjr0]

SandeepMedikonda please find below the link for the video on youtube.

I will take some more snapshots later with the mesh details. This problem happens with any mesh. In the case of the video, I am trying to generate a simple default mesh.

Yes, I am at a University and this problem is happening in all the computers that have the 19.1 version installed that I tried (4 different machines).

Later I will post the details of the machine as well.

Thanks.

[Sandeep Medikonda]

Ok, yeah. Please provide those details and also the University name?

Once you do, I'll try to reach out to your account manager and we can work from there. 

If the problem is replicable on all machines at one university, it is possible that some anti-virus or an application might be blocking the meshing executable from running.

Can you confirm if this is a problem with a previous version as well, i.e., 18.1 or 18.2?

Regards,

Sandeep

[luizjr0]

SandeepMedikonda, Please, see below the details of the mesh (everything on "Default"). The machine I am using has the following configuration:

Intel Core i7-4790 CPU 3.60 GHz

Installed memory (RAM): 8.00 GB

System: Windows 10 Enterprise x64

 

I am writing from the University of Nevada, Reno. 

The problem occurs in the 19.1 version only. The computers with previous versions installed (18.2, 18.1, or 17) do not present the error.

I am not speaking about meshing, but creating models! So I am not able to create a simple line, Only the first point to do and not to create the second one. So I am not able to create anything at all! Thanks for understanding!!!

[Georgiro]

So as I said the problem is on Ansys 19.0 and also on 15.0.7, so before I used normally 15.0.7, but I cannot now. So what can be the problem? Thanks

[Georgiro]

 Basically, please, read this, because I am not able to create even 2 points of a geometry, not a plane, etc. So can you please start to think about it. And this happend on my before using 15.0.7 and now 19.0. Absolutely impossible to work with it!!! Thanks for understanding

Let's get your license issue resolved in the other thread.

[Sandeep Medikonda]

luizjr0, 

Getting some logs would help out.   The only personally identifiable information in these logs will be folder names.  No geometry, model, mesh data, or machine identities will be logged.

* First though, perhaps it is a permissions issue.  Are you running as admin or have admin privs?  Are they installed in default location?  What is the location of the TEMP folder via %TEMP% and do they have proper write access to it?  (Meshing will create a subfolder in here, so there should be a %TEMP%/AnsysMeshing folder as they tried to run mesher)

* Second thing I would look for real quick is seeing if the problem is unique to sweeping (as this model is sweepable).  

Right click Mesh, choose Insert --> Method.

In details view, click Geometry.  Go click the cuboid in the Graphics window, then back to Geomery and click Appy.

In the details view, change the Method field to Tetrahedrons and try again.  Change it to Multizone and try again.

* Still no answers... move on to logs:

Turn on Beta Options:  Workbench Project Page, Tools -->  Options -->  Appearance -->  (scroll down)  Beta Options

In Mechanical, right click Mesh, and select Diagnostics (Beta) -->  Enable DSMesher Logging

Generate Mesh.

This will create logs in %TEMP%/meshlogs

* If Diagnostics is not available (older version), or we don't get a meshlogs subdirectory, activate logging manually and keep logs out of the TEMP folder.

1. Close Workbench down completely.

2. Find the attached file (AnsMeshingKeys.xml) which contains keys that will activate logging.

Copy this file to a location that has write access. (I place it on the D: root)

3. Open the file, and in line 3, change the value to a directory where they want to dump the logs into. (I have it set to D:MeshingLogs)

4. Create the directory to ensure it exists and is writable.

5. Create an environment variable that points to the folder where the xml file is located  (Notice, no trailing slash)

AnsMeshRegistry=D:

6. Restart Workbench so that is consumes the new environment variable.  Run the entire workflow.  Several log files should be generated in the directory you chose earlier.

The files will be helpful to us if they can be sent it.

Remove/rename the environment variable to turn off the logging behavior whenever desired. 

Regards,
Sandeep

What I have made is to reinstall Windows 10 Home and it started to work it normally. But, so much thank you!

[MikeW]

This may only be a solution for some fringe cases, but I was having this same error in ANSYS 19 and was able to fix it by uninstalling software called Amplitube.

[Sergiorojas]

This may only be a solution for some fringe cases, but I was having this same error in ANSYS 19 and was able to fix it by uninstalling software called Amplitube.

Actually it worked, I had this problem before with another computer too (which has Amplitube installed), I just uninstall it and now meshing works. Thanks for share it.

Resolution for one person:
The meshing logs suggested by Sandeep Medikonda did not help greatly. They only showed that the meshing process did not start. This is called AnsMeshingServer.exe.
General advice when the meshing process does not start is to check things like virus scanner logs (turn off temporarily), firewall exception, and Windows event logs. For Windows log, you can open a "File Explorer" browser, then right click on "This PC > Manage." Expand under "Event Viewer > Windows Logs" and look at logs for "Application" and "System." Possibly even "Security.
This can also happen when other software installations on the machine have placed older dlls in the C:Windowssystem32, and Ansys can use these instead of the dlls found in the installation at C:Program FilesANSYS Incv{version}tpIntelCompiler{build_date}winx64". Compare file names is these directories. If any have the same name, you can rename (add ".old" extension) to the dlls in the Windows direction so that it uses Ansys dlls. In one customer's case these were the interfering dlls: libiomp5md.dll, libmmd.dll. But the interfering dlls may be different depending on the older applications installed that are interfering with Ansys. Once you have found the problem dlls, you can decide if you want to delete them or update the software that origjnally installed and is using them.
Restart workbench after renaming the dlls.
This problem is discussed in Ansys knowledgebase solution 2058100.

I had the same issue with Ansys Student 2021 R1: "The mesh generation did not complete due to poor quality elements or incorrect input. Please try meshing with another mesh method or different mesh options."

I tried mjmiddle solution but it doesn't work for me.

So, I tried MikeW idea and it works. I'm Amplitube4 user but Ansys is more important for now. Thank you!

I found a solution to this problem. If the OpenMP libraries are messed with by another program, the mesh generation will not work. The file I found I needed to replace was C:WindowsSystem32libiomp5md.dll. I grabbed the latest version and replaced it and everything worked fine again!

Thanks tmar89, this fixed the problem for me as well. I had 2020 installed for a while, and it had functioned perfectly last spring, but when I tried to generate new meshes, I would get the error that the others got. If I opened old solutions and started up the mesher, the moment I clicked on the Mesh entry to view the mesh, the Mesher would crash. I uninstalled 2020, removed any remaining files in the ANSYS Inc folder, then installed 2021, but got the same problem.

It turned out I had an older (2013) version of libiomp5md.dll. I replaced it with the version on the Ansys ISO files, and it runs now.

I couldn't find AnsMeshingKeys.xml can you help me

[Burak Kılıç]

I am having exactly this problem. And I've also seen a few other people who had the same problem and couldn't find a solution on the internet. The above question is simple, well-defined and almost 5 years old. This problem should be fixed!
