I created a .msh file by Fluent meshing. I start Fluent solution mode then read mesh, then I active dynamic mesh, everything is OK until here. But when I active remshing function, the Console report:

prism and sizing control settings,

After several minutes, the console report :

Error: %create-sizing-controls: wta(int)
Error encountered in critical code section

What that means? what can i do to solve this?

Hello, 

 

Which version of Ansys Fluent are you using? I would recommend you to check this out in the latest version, 2023R2.

Hello,

Thanks for your reply. Let me describe my situation more clearly.

I tried latest version 2023R2, also 2023R1, the issue still exist. However, there is no issue in 2020R2.

I also doubt if the issue origins from Fluent Meshing. Because i load other mesh files then active remeshing, the cosole report "prism and sizing control settings", but won't crash. Then i can set remeshing parameters.But when i load my mesh from Fluent meshing, then the issue happed. I doubt if there is no default value for remeshing. But Fluent meshing seems can't setting remshing parameters for solution mode.

By the way, I generate the fluent meshing throgh watertight geomertry workflow. And there is no error in the mesh files, it can be loaded and calcuation. I can load one other mesh, after active remshing, then replace mesh. But is inconvenient, please help me with that issue. Thank you very much.

Hello,

Which type of mesh (tet, poly) are you using? Did you try Unified remeshing?

[kevin.anny]

Dear Essence,

Thank you for your reply. For my case, hexcore mesh is used. That is tet at surface, hex at zone core. Because once the remeshing is active, Fluent is crashed right now. I have no chance to change from method remeshing to Unified remeshing.

Hello,

Can you try using only tet and check that again?

[kevin.anny]

I tried full tet mesh, the error still exists.
