hi,

the mesh generation of my model takes almost 2 days now and still ongoing! I know that it is a complex model but I want to know whether it is normal to take such a long time or should I stop that.

and can you give me some tips on how to reduce meshing time? (mesh resolution is already set to the lowest)

many thanks,

Farnaz

Hello  farnazhd66

Mesh generation taking 2 days doesn't seem to be normal. Are you trying to generate mesh using physics aware meshing approach (Mesh task doesn't appear in the workflow) or manual meshing approach (Mesh task appear in the workflow)? Can you try manual meshing approach and modify the global mesh settings based on geometry details, and set Mesh controls - Element shape as tetrahedron for all bodies and see if that helps?

Naresh Patre Hi,

many thanks for your reply. actually, I had used a manual meshing approach and element shape was set to Hexahedral. This time I have changed it to tetrahedral as you said and hope it works this time:)

But I think I need to simulate a quarter part of my model using symmetry condition to fasten up the process. Can you please tell me how I can set the symmetry boundary conditions?

 I know one cutting plane should be slip wall and the other insulated wall, but I don't know how to apply :/

Hello  farnazhd66 Under Fluid Flow condition, you have an option called ' Symmetry'. Click on symmetry and select the face about which you would like to apply symmetry.   Could you please confirm if the mesh generation was successful?

hey,
 

many thanks for the help. with tetrahedral and using a 1/4 of my model, meshing works.
thanks a lot for your help one more time.
