3. The explosion of a solid explosive material in the form of an infinite cylinder may be described by d du -1 (d) = 2e", 0 <r < 1, with BC: (0) = 0, u(1) = 0 r dr dr The exact solution of this nonlinear equation is: u(r) = In (1+r²)² Find the FEM solution using two linear elements and compare with the exact solution.
