Pure Hex mesh

I am a student research assistant and am in a little bit of a fix. 

 

I have a geometry as shown in green in the figure attached. As its a regular geometry getting a hex mesh is not a problem except for one complication that i require an extremely fine mesh in the region shown in in red and gradually increasing mesh size for the rest of the geometry. This is couple with a chamfer ot one of the edges. 

Is it possible to get a purely hex mesh for this geometry and mesh requirement. If so how.

    'Hexa only' maybe not possible with your model. But with some 'penta' I think that's possible.

    Send me your geom, I'll try it image/emoticons/default_smile.png' alt=':)' srcset='/emoticons/smile@2x.png 2x' width='20' height='20'>

    Here's an example of mesh.

    if there are pentas in model, we can switch it to pure hexa model by shiftF6>split into hexas

    Yes, it's possible.

    But 'pure hexa' with bad jacobian is not better than 'dominated hexa with some penta' by point of view of finites elements quality.

    It's so simple.

    Build your surface mesh (on small diameter for example) with this varying density.

    Then do mapping mesh to big diameter surface.
