[GiDlist] quadrilateral mesh on a cubic domain with a ball h

[Seungil Kim]

Hi, all

I would like a structured quadrilater mesh in a cubic domain
with a ball removed.
For exmaple Domain = [-2,2]X[-2,2]X[-2,2]\a ball radius of 0.1
But a problem is that the mesh I would like to generate
is finer around the sphere of radius 1 than the other part of the domain.
Could you let me know how to generate the mesh?

Thanks,

Dear Kim,

first of all, you should divide your volume in 6-sided volues, to be able to
mesh all of them with structured quadrilateral. A cube with a shpere hole
inside cannot be meshed as structured.

Then, if you want to concentrate elements in the sphere, you can select the
option 'Mesh-Structured-Lines-Concentrate elements', which allows you to
apply concentration weights to the end nodes of a line, leading to a
concentration of elements where you want.

Kind regards,

ABEL
