How to refine mesh in center oof my model (Plate)

[anto_772]

Hi guys, I'm trying to refine my mesh in the center of my 3D-plate model as a cross (I upload an image as example). I want to know if exist any option to make the mesh smaller as it approximates to the center and grow as it gets away to the edges.

My method was divide the model in sets and use the seeding tool to define the number of element per edge,but I don't know if it's correct or if could change my final results.

Thank you for your help

You can partition your geometry to get new edges where you can add mesh seeds.
Beside the global seed you can use local seeds, that also allows a biased definition.
