This question seems easy but in fact it is NOT. i do not know how to mesh a ball with ONLY brick elements (no tetrahedron) using ANSYS. Please kindly send me an input file contains the meshing to a.abeed [at] tu-bs.de

You can cut the ball into 8 identical parts (using working plane to divide the volumns), use the MSHKEY or MSHAPE command to let ANSYS mesh the volumn with only hexahedral-shaped elements, then mesh one by one. One more point, before you mesh them, specifiy all lines with the same number of element divisions.

Thank you very much for
Thank you very much for helping me, i still have small problem, how can I refine those element surrounding the south pole of the ball.
the implementation of your instruction is available for beginners like me:
/PREP7
ET,1,SOLID45
SPH4,0,0,1 ! Create a solid sphere of radius 1 centered at origin
VSBW, ALL ! Divide the sphere, cuting knife is the current WP
WPLANE,-1,0,0,0,1,0,0,0,0,1 ! change the work plane (New cuting knife)
VSBW, ALL
WPLANE,-1, 0,0,0,0,0,1,0,1,0
VSBW, ALL
!WPCSYS,-1
LESIZE, ALL,,,12 !
TYPE,1 ! set element type attribute pointer to 1 (SOLID45)
MSHKEY,1 ! Mapped mesh option
MSHAPE,0,3D ! Hexahedron Elements option
VMESH, ALL ! Mesh All The Volumes
FINISH

Anybody can help
Anybody can help me.............
I have a problem while meshing. I want to mesh a volume with brick elements. The volume has circular arc shapes in it.
When i try to mesh with brick elements, i am getting the message as "Invalid Topology"
How to overcome this?
Please help me.............
