mesh spheres embedded in a semi-sphere
mesh spheres embedded in a semi-sphere
(OP)
I'm modelling the interaction between an indenter and an organ of semi-sphere shape.
It is assumed that there are three small sphere nodules embedded in the organ. Thus there are three sphere holes in the organ part and three sphere noodles are they filled to these holes in assembly step.
But when I tend to mesh the organ part,there is an error coming out saying:"The regions highlighted in magenta cannot be meshed automatically using the assigned element shapes. They must be partitioned, assigned a tet shape, or manually meshed using the Create Bottom-Up Mesh tool." as attached to this post.The magenta regions refer to the three holes.
I followed this instruction, i.e., partitioned the part with datum planes,changed the element shape,but it still cannot be meshed.
Actually, it succeeded for once (the holes are also meshed), but when I submitted the job, there is one error saying some elements (the holes) are not assigned sections. But these holes are empty, they should not be assigned sections...
It is so confused, anyone can help me? Thanks.

Thanks for your reply. Actually the highlighted area are holes embedded in the semi-sphere. Any suggestion? Thanks.
RE: mesh spheres embedded in a semi-sphere
The 3 spheres are filled with a different material in the assembly? If so you can merge/combine the geometry so you have a coincident mesh.
I hope this helps.

Thanks for your advice, I merged the nodules with the cortex. But the merged part still cannot be meshed (I used tet element type) as shown in the attached picture. Any suggestions?

Thanks for your reply, the attachment is the model.
RE: mesh spheres embedded in a semi-sphere
Here is the section view of the model.

I thought you referred to the appearance of the model...
I uploaded the cae model to this post.
RE: mesh spheres embedded in a semi-sphere
Assembly>Merge/Cut>Merge Geometry and Retain Intersecting Boundaries>Select medulla-1 and Part-6-1.
Mesh>Mesh Controls>Tet
Now you should be able to mesh your part.
I hope this helps.

RE: mesh spheres embedded in a semi-sphere
I followed your steps, it works and the part can be meshed finally!! Many thanks!
Actually, the error saying some elements (the holes) are not assigned sections happened again, but after I assigned sections to these regions it was solved!

I'm glad it worked for you. Your welcome.
