I'm wondering which is the best way to mesh a cylindrical body with holes. I cant eliminate the holes because they are important for bolted connection using beam connection body-body. I watched different tutorials but in this case the body is cylindrical and I cant use the same mesh way than in a hole plate.
Could you recommend me any ways to mesh this kind of bodies to get a good quality mesh using 3d mesh?
An example of the part, i cant share the real body because this project is confidential, is the following:

I suggest you to please check meshing user's guide: Enable Washers (ansys.com)

I was looking at the article that you sent me, but it seems that Washers is only avaliable in sheet bodies, not in 3D bodies. Do you have any help about this kind of mesh for 3D meshes around holes? In my project its not possible to use 2D element.
I tried inflation aswell but the element quality using this tool is poor and i need to use too much elemento for getting a good mesh using inflation.
Thanks in advance.

In SpaceClaim, copy the inner face, and paste it to get a surface and delete the solid. Import the surface into Mechanical to mesh the surface. You can use inflation around each hole. Finally use the Mesh Pull feature to extrude the 2D shell elements into 3D solid elements. This should result in good quality elements.

This idea sounds good, i will try it.

After you have the surface and deleted the solid in SpaceClaim, go to the Repair tab and click on Extra Vertices to remove the vertex on all the holes. You don't need them and removing them will give the mesher more freedom to make the highest quality mesh.
