hi I am trying to generate elliptic grid by solving laplace equation. Now i am required to invert the equation. that is, make the dependant variable independant.. when i do this i am getting non linear terms.. like first differentials squared.. How will it descretize this system then? if i descretize i get quadratic numerical equation, and its getting complicated. but is it how i should do it?

thanking you
