    Hi! I would also like to know how to create a solid mesh made of hexas and pentas in a sphere using HyperMesh. Well, in a half-sphere. Maybe someone can help? Thanks!

    Hi ester,

    hard to explain in words, but in general you have at least two approaches to hexmesh a sphere:

    1) 'apple'

    - cut a cylinder from one pole to the other

    - cut the remaining outer solid, shell mesh the cutting plane and spin the shell elements

    - shell mesh to top or bottom of the cylinder and drag the elements from pole to pole

    By cutting out the inner cylinder, you can avoid wedge-shaped penta elements along the polar axis

    2) 'inscribed block'

    Even harder to describe in words, but this approach is explained in detail (with a quarter of a speher) in Tutorial 'Creating a Hexahedral Mesh using the Solid Map Function - HM-3220' (Steps 2 and 3)

    Regards,

    Stefan

    Hi Kevin, I dropped you a mail!

    Hi Hettel, if I understand your steps correctly, about the 'apple' method, I think by cutting a cylinder, what we will get is a flat circular plate and not a sphere. Maybe I have not understood your description. Do you have any figures to describe your mesh methodology? I'm currently trying to mesh a shpere and the air around it so any help from you guys will be very very greatly appreciated!=d>

    Hi,

    no, by cutting the sphere with the cylinder, the 2 'polar' cutting planes are curved. To obtain this you should use the following boolean operation for cutting:

    (advanced) operation: A*B (keep all parts)

    combine through: none

    Create a Cube inside that Sphere and solid mesh it. Now its easy for us to create solid mesh around that cube inside sphere
