Hi Cubiteers, not a tricky one I think, tedious but not tricky. I’ve got a geometry which I want to chop up into bits which make sense for a thermal hydraulic problem, the geometry looks something like below;
Annoyingly, the human eye can see where all these curves meet straight edges and make decomposition easy. My terrible caffine induced jitters aside, is there some exisiting infrastructure which will make quick work of splitting like below?
Have you already tried to use the Sheet Extended From Surface webcut?

create cylinder radius 1 height 0.1
create brick x 2 y 0.2 z 0.1
create brick x 2 y 0.2 z 0.1
create brick x 2 y 0.2 z 0.1
move vol 2 3 4 x 1.5
move vol 2 y 0.5
move vol 4 y -0.5
unite vol all
compress
Volume 1 copy rotate 90 about z
Volume 1 copy rotate 180 about z
Volume 1 copy rotate 270 about z
move vol 2 x 3
move vol 3 x 3 y 3
move vol 4 y 3
unite vol all
compress

Another approach could be to split the surface across vertices.
And use the surface for a sweep.
