Hello
I’d like to ask if it’s possible to refine the purple volume which has an irregular shape. This volume has been meshed by sweep algorithm.

Thanks

Hi @jflorescuba!

I can give a lengthier response later, but see if this script gives you inspiration:

reset

bri x 1
create Cylinder height .1 radius .1 

move vol 2 z .55
imprint all 
merge all
mesh vol all

unmerge all
delete mesh vol all except vol 2 propagate

refine volume 2  numsplit 3 bias 1.0 depth 1 
imprint all
merge all

mesh vol all

Thanks, it seems to be a good option, i will try.

I’d like to ask you if maybe there is another option without sweeping the refinement to the bottom surface of the green volume.

You can do
`

refine hex in volume 2

`
from the command line to do a 1-to-3 refinement in every direction.

You will likely get warnings about element quality because of the refinement.

Do you have a circular surface defined on the volume? Then you could try the command above that takes a list of hexes.

refine hex in face in surface 7
