How can I get non-uniform mesh?

For example, suppose I need to mesh a sphere with tetrahedral. I want the center is very dense, while the outer surface is coarser. What do I do?

I tried the edge distribution, but it does not reduce the element number much.

Thanks in advance.

Hi

you can add one or several "layers" (check the geoemtry node), hence get a sphere inside a sphere ... then change the desired mesh density per domain

Good luck
