Dimple (Hemisphere) Meshing
 

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! :)

This is already done in this thread : http://www.cfd-online.com/Forums/ans...-tunnel-2.html

You can find detailed discussion, blocking strategy and relevant ICEM files here.

Please tell me how to mesh a dimpled plate as a volume mesh in GAMBIT 2.4.6. I can provide you the file if you want it..
Trimitive Mesh are possible but why not Hex Type (Cooper).
Please help me..

can you post some pics?

Following is the image of the flow domain of the plate and the tripimitive mesh that was made,

Attachment 19895

Attachment 19896

decompose each dimple into five parts. once centre square/rectangle and four side squares/rectangles.

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...

Helped a bit, going through it.
Will post for help if any problem arises.
Still thanks alot...

Project to data base will do the trick.
