Mesh Generation of a Solid Ball
« on: December 12, 2014, 01:53:47 AM »
Hi,

I am a fresh user of FEAP. I have a really really basic question, how to generate the mesh for a solid ball?

Not a hollow sphere, but a solid ball.

Very appreciate to any answers :)

The 'typical' way to do this is to create a cube.  Then to each face of the cube attach a sector with 5 flat faces and one curved face on the surface of the sphere.

If you have never done this type of meshing start by trying to create a mesh for a solid circular disk in 2D.

An example for a solid sphere and a spherical surface is attached.  Note that all the nodes on the outer surface may not be generated to have the actual radius of the sphere.  It is useful to write a simple mesh manipulation command (umani1.f) or solution command (umacr1.f) to move the nodes to the correct radius.

With the very helpful input files, I did the sliding contact with two spherical bodies in 3D.

The animation can be found at YouTube...
