[ICEM] Is there an option to get radius dependent edge length of elements

jacktat7 · January 28, 2021, 08:05

Hello,

I was wondering if there is an option to get edge lengths that are radius dependent. ie the smaller the radius of a tube, the smaller the elements are in that part.
I am modeling bloodvessels which become quiet narrow (and thus high Reynolds numbers). To reach convergence I need more elements in these parts of my mesh and I waas wondering If there is any type of local refinement based of radius.

Thanks in advance.
Cheers,
Jack

Hello Jack,

Have you used a structured or unstructured mesh?
