I want to create a basic surface z=square_root(x^2+2*y^2) using only geometry nodes like this: https://i.sstatic.net/TeKkf.jpg

I don't know to which type of mesh I should apply this geometry nodes.

In my opinion, I have to add a vector as input in the geometry nodes but nothing is drawn for me

Can someone help me?

thanks

I don't understand why this nodes configuration doesn't give me another desired function z=square_root(4-x^2-y^2) enter image description here

You could just generate a Mesh Primitive > Grid, and set its point-positions to (x,y,f(x,y)):
