How to mesh a sphere in Hypermesh

Hello everybody,

 

I'm currently encountering problems to mesh a sphere in Hypermesh. In fact, I manage to mesh in 2D its shape, but I cannot mesh the inside of the sphere in 3D. Or at least it doesn't give me the good result by using the following tools 'drag' or 'spin', and I don't know which other tool I have to use..

Can someone help me to work this thing out? You can find the model attached.

Thanks a lot,

    Hi @Rahul R,

     

    Thank you for your answer. I already saw this video but as I didn't start like that, I wanted to know wether it is possible to mesh the whole sphere with my method (I started by meshing the shape in 2D and then wanted to drag it toward the inside) or not.

    But thank you, and I am gonna try your method.

    If you start with 2D external meshing, you can 'fill' to get solid mesh. But in this cas, you get something like TET elements.

    RahulR,

    Thanks for posting this video.  Provides a good & innovative alternative way of accomplishing a hex mesh of a sphere.

     

    What is the difference between trimming of a solid by 'Bounding Lines' vs 'Sweep Lines'? In your video, @ around 8:35, you use bounding lines option to trim a solid. Could the same result be accomplished by using 'sweep lines' but with instead of 'sweep all', selecting vector distance N1-N2?
