Does any body help me finding the solution for this?

Please exit workbench. 

Please rename folders in C:\Users\USERNAME\AppData\Local\Ansys

Then try.

Hello Keyur,

I'm facing the same problem. How am I suppose to rename the folders. Could you please describe the process? 

Regards,

Cenk

You need to use Windows Explorer, find the file/folder and rename it.

Hello there. I have exact the same problem, which cannot be solved by re-installing or changing the folder name. (My folder names are all in English characters already).

I see this error in 2D or 3D geometries, no matter it is designed in DM or SpaceClaim. I also tried different size of mesh structure, it is still the same.

 

I would be chuffed to bits if someone could help out.

Thanks in advance.

Edit: After one day, I have noticed that the .meshdb file is created in "global" folder, while the geometry file is created in FFF-->DM folder. And there is no .msh file in the FFF folder either. However, as I checked it on another ANSYS on another computer, I have noticed that the mesh (.msh) is created in FFF --> MECH folder, while .mshdb is in global. I think this is the normal situation because ANSYS works well with that computer, however, not in mine.

I thought the problem could be it. However, I don't know how to solve it. I appreciate your help.

Save the Workbench project. Open Meshing and check the mesh was created correctly. On Workbench if Meshing has a lighting strike icon right click on that box and update. Then try Fluent.

Thank you very much for your concern, Sir. However, it does not work, either. The update option does not work at all. For instance, when you open a new Workbench file, create a very simple 2D square geometry from surface from sketches and go to Meshing, then you have to click on Generate Mesh, instead of Update in order to perform your changes on the mesh. In short, I just want to explain that Update option does not work neither in Meshing nor in Workbench interface.

When you complete the meshing somehow and close the window in order to click on Setup and go further, then you notice that the mesh is not updated and there is a red cross on the lightning icon, just as the user "ghost" posted a screenshot at the beginning of this thread.

I think I am out of solutions. Just wondering what causes it... 

Appreciate for your all suggestions for help.

The red cross means something failed during meshing or data transfer, open Meshing and see if there are any error messages.

Thank you for your consideration sir. However, the message is already the problem I had previously explained. Just as the screenshot of "ghost" at the beginning of this topic.
