How to mesh a partial sphere

Postby yuhongyu » Wed Jun 26, 2013 7:44 am

I want to mesh a partial sphere with a circle for surface meshing scheme and a sphere for volume meshing scheme. However, the sphere for volume meshing scheme demands Volumes topologically equivalent to a sphere and having one surface. On the other hand, my partial sphere have two surfaces, one for circular section, and the other for partial spherical surface. So I am not able to mesh the volume of partial sphere.
Actually, there is an example of this volume where the guide of Sphere offers in Trelis 14.0 Documentation. So I'm not sure if I build the partial sphere in a wrong way, which has two surfaces.
It will be very kind of whom to help me with this problem. Thanks a lot. :)

Partial spheres can be meshed by cutting a cylinder through the core and cutting the partial sphere into two sweepable volumes.

Try this

reset
create sphere radius 10 ypositive
create Cylinder height 25 radius 1
rotate Volume 2 angle 90 about X include_merged
webcut volume 1 with sheet extended from surface 3
delete Volume 2
webcut volume 1 with general plane xy noimprint nomerge
volume all size auto factor 2
imprint all
merge all
mesh vol all

Did I understand your question correctly?
