Meshing volumes 1

[Robert000]

Hi all,

I have some problems with mapped meshing. I would like to create brick mesh with regularity on boundary areas (inlet, outlet, top, left and right, bottom with finest mesh) as well as on object areas(finest mesh).

How can I do that?

Thanks a lot,

Robert

And the geometry:

Hello,

It's not so simple. This code generates your geometry so it can be mapped meshed, but the problem ist at the corners of the cylinder, where small lines are builded. It can be meshed but with very small elements.
