Hello everyone,
I used Ansys DesignModeler to create geometry with a circular bore, please see attached pics. I wonder how can I modify it to get a sweepable body meshing in Ansys-Meshing. Any hints or suggestions are so valuable to me, thank you in advance.
Hello,
Is the tet mesh for a solid or a fluid region? If it is a fluid region, are the top and bottom hex meshes solid regions?
You can easily get 10 layers of hex elements around the circular bore in the tet mesh by adding an inflation mesh control.
Regards,
Peter

Dear Peter,
Thank you for the reply. all bodies are fluid regions. I added inflation but I didn't get a uniform mesh as shown in the post. Any hints, please. Thanks
It's more important to have proper element sizes, even if they are prism wedge and tet element shapes.
The outer geometry looks like a symmetric slice of a cup-shaped container. I expect the conical face of the cup is a wall, so you need to add inflation there. The bottom of the cup is a wall, so you need inflation on that face. What is at the top of the cup? What is the purpose of the different bodies at the bottom and top? Have you put the three bodies into a multibody part?
Please explain some of the other boundary conditions. You want smaller elements where you expect high gradients in solution quantities. Have you run a preliminary solution?
Regards,
Peter
