I tried but did not work. It seems I am going wrong at giving BCs. Please try extruding that mesh with 0.19 spacing and 32 layers.

Please give me directions to work on 3D mesh. Please its urgent.

 Hi, do you know how to mesh the connection between two cylinders properly when one small cylinder is perpendicular connected to a bigger one at the top/bottom. (picture 1 +2) I always have bad elements where the small cylinder meets the ceiling of the bigger cylinder. (picture 3) Is there a good way to make the connection without these bad elements or are they unavoidable respectively of low importance? kind regards
You can use y-block for sharp corners Quarter O-grid from vertices and !!!!!! Why?

Thanks for the hint. I've already tried Y-blocking but it's not working...
Anyway, the blocking in this geometry looks good. This is just a minor problem.

Here is one picture and I also added the .tin + prj. + blk. + .fbc files. When you apply the quality-criterion Det 3x3x3 at the pre-mesh you will see the region with the bad elements.
