Mapped meshes and spheres

Hello,

A quarter cylinder is easy

But what about a quarter sphere with the top chopped off?

The model really is as simple as it looks.

I can't be looking at the meshing problem in the right way.

Any thoughts

Thanks

    OK,

    example 2 (volume regions only, but sphere with the top chopped off).

    regards

    Thanks Paul,

    I thought along similar lines but with volume regions in a part rather than an assy of parts. I couldn't get it to work.

    It is a reasonable amount of prep.

    Consider the following. just spent 10mins including geometry creation and manual shell meshing in Independent and 5 mins to remember my log in and post.

    (I'm not suggesting for a minute that the modern user would want to do this, I just thought that since my last foray into this the methods may have moved on)

    Thanks

    Paul,

    it's not a bad thing Independent is now history.

    The 'revolve' of shell elements was easy just so long as the user made sure it was only element edges were along the axis of revolution.

    Using the Creo functionality we have to approach it differently and are forced to have the cylindrical central volume region; which isn't a problem.

    You'll need to slice your volume up, but use the butterfly meshing scheme. The mesh below is all brick elements.
