How to control the element size for 3D mesh?

Hello,

If you are doing a Volume tetra mesh then the panel gives you an option to input the element size. If you want a different element size at different areas in a component you have to mesh separately and each time input a different element size. (This is not recommended as then the mesh will have some connectivity issues)

If you are doing a tetra mesh then inside the 'tetramesh' panel there is 'tetra mesh parameters' panel where you can input the maximum and minimum element size and manipulate the element size.
