How to mesh a spherical solid? please help... thank you
Hello,
If you have a sphere primitive, then the best way is to cut the sphere into 4 parts.
First step: solid edit->trim with line->bounding lines->extend trimmer
Second step: solid edit->trim with plane->with plane (choose the plane, e.g. x->0,0,0)
Normally i'm meshing one of the inside surfaces (quarter) with the 2D automesher. Then i'm spinning the mesh by 360 deg and e.g. 24 steps.

Mario
Hi,
You can mesh a sphere from a cube (hex8 element),
just split it and then project outer nodes on sphere bound surfs, repeat these two steps until you get enough fine mesh
To split a hexa you enter split element (Shift+F6)/solid element/split into hexas
Thanks a lot....
I imported an iges model into Hypermesh.... I'm not able to mesh it.... can i be able to post the file..... please kindly help...
Thanks and regards,
