Hi everyone,

I am trying to get the maximum, minimum, and average element size in a **3D mesh**. I found there is a command _hTriangle_ that can check the mesh size of a 2D mesh. I want to ask if there is any way to get the size for a 3D mesh?

Thank you in advance!

Thank you for the answer!  
Is there a way to directly check the mesh size for a 3D **volume** mesh in freefem?
