can anybody help me please how to mesh a Hemisphere in Gambit or ICEM CFD? I want structured meshing but gambit is unable to do that, gambit performs tri-primitive meshing on each surface. you can take hemisphere of any dia. I can provide the geometry if anybody is willing to answer in detail.

Thanx in Advance!

I have done it in Pointwise/Gridgen v15 with O-H topology by separating it into 5 parts, but the problem i am facing is that when H Grid is to be made it, makes a simple straight face grid instead of following the curve of the dimple.
Any suggestions???

I just made an effort on sample geometry (through design modeller). Meshing was done in ICEM Hexa.

a small trick for this kind of geometries, while making geometry, make just a sector, mesh just a sector, and duplicate it...
