Create irregular grid in oval planar surface

Hi there, I am trying to divide an oval planar surface (pic1) with a domain to create a grid with different sizes. Although it works for a rectangular planar srf, I get this result (pic2) when I try it with the oval shaped one. Pic3 shows what I would like to achieve. Maybe I shouldn’t be using the isotrim component. Any help appreciated, [1][3][2][00][000]
