How to mesh a sphere as a solid?

Recommended Posts

Hello persons,

I need to simulate a ball colliding with a plan. For this I need mesh the ball as solid.Could someone tell me how to do this?

Thanks

Hi frogmam

You can try trimming the sphere into quarter spheres and make it mappable and carry meshing.

Very Thanks!

@Q.NGUYEN-DAI: I liked this mesh you have a tutorial to make it?

@frogmam: Here is my example how to make hexa mesh for a sphere:

Load my HM model and you straightaway understand how to do that

Hii

This is my procedure

1. make a sphere

5. make a temp node

6. make a hexa

7. project a temp node on sphere

8. make 3 hexas

9. equivalence

11. split hexas

12. project outer nodes on sphere (select 3 nodes > by face)

13. reflect hexas to form a sphere

14. equivalence

15. smooth hexas

finished:

@tinh: my method is different, no project at all. Your result of step 12 is not so good, at border of sphere.

Yes, so at step 15 i smooth the hexa and result {last image} looks not bad

anyway I hope smooth operation for solid elems has options like for 2d elems (size, shape, angle,..)

HTH,

Hello,

Would you please take snapshot of all steps you have done.

Hi frogmam

i´ve try to open your own version of the meshing sphere but it isnt compatible with my 12.0 version can you please make some screenshot

Thx

Try this file:

Sphere_12.hm

Hey,

thx for this file. I´ve already modeled something like that but my Prof want that the quad elements on the circle face are feiner as possible and the rest of elements doesnt matter because this will be the contact surface between sphere an plan we have to analyse. how could i realize it in hypermesh?

How about spin option? See attached screenshot.

Spin method is ok too. But you have to accept some PENTA elements
