Partitioned mesh in 3D issue with seeding in 'z' direction
Partitioned mesh in 3D issue with seeding in 'z' direction
(OP)
I would like to partition the centre of a plate with a higher resolution mesh but it seems that the through thickness dimension of both partitions are locked, see pictures.


Whenever I try to change the inner partition's through thickness seeds the outer partition's through thickness seeds are automatically updated to match & vice-versa.
Is this a constraint on the meshing that I just have to live with or is there a way around this?

I should clear a few things up. The central region is not a hole just a partitioned part of the volume of the plate. Its the area that will be hit by a number of projectiles which is why I want that area to have a higher mesh density.
Would it be possible to mesh the central partition with hex and the outer with tet/hex mixture?

Another way would be to partition the whole region using the internal faces to create 9 cuboid regions (including the centre) and redefine the regions as swept regions. You could then redefine the sweep path to be orthogonal to the original defined path through the thickness. Uncheck the box that says use mapped meshing where appropriate and delete the outer seeded edges that Abaqus created so you only have your internally defined seeded edges. Attached is a picture of a cube where the sweep direction has been changed so that the through thickness edge has 10 divisions on one edge, with 5 divisions on the outer edge. Presumably the technique would work on the 9 regions in your model when combined.
