question about castellateMesh
 

Hi,

I wanna generate hexahedral cells to my closed-stl model.
So i only run castellatedMesh ,without snap option.
but, generated cell having not only hexhedral, but also polyhedral cells !!
what is this behavier?

my model is like a big dome ,having zero-thickness wall into.

how can i generate only-hexahedral model?
or, how reduce polyhedra?
someone help me.

regard.

After that, I checked myself and understood the meaning.
When the mesh size changes in castellatedMesh , the larger cell is recognized as polyhedral.
I should have checked it soon.

thanks.
