Hi,

I am meshing my geometry using the fluent meshing tool. When importing the CAD file, fluent generating the zones, and regions by itself. How can I prevent it?

When generating the surface mesh, I am getting an error "Error at Node 0: tg-delete-duplicate-faces: wta[1](zone) [421]". What could be the reason for getting this error? See the attached image. Please note that in the workbench, geometry is meshing without any problem.

This is very common error. 

Sometimes it happens due to error in the geometry. Please check geometry in SpaceClaim. 
Select geometry in structure tree --> Use right click --> Select Check Geometry. (Or Tools - Fault Detection in DM)
The geometry should be error free to proceed. 
If geometry has any errors, please modify/recreate geometry at those places. 

If geometry is error free then  please check if you have multibody component in SpaceClaim. If it is multibody component then you will need to use Workbench → Share option before going to Fluent Meshing. 

Please go through help manual for more details 

Please check following videos

The geometry is error-free. Also, share topology is applied among the multibody components.

Please check visually in Spaceclaim if share topology is successful or not. The error in Fluent Meshing indicates that share topology is not successful in SpaceClaim. 

Please go through help manual for more details
