Hi everybody I need help to solve the following problem in finite element A field variable f(x,y)=xᵌ y is defined over a rectangle domain Ω={K: 0≤x≥4 , 0≤y≥6” Given the expression g=∬_(0 0)^(6 4)▒〖X^3 Y dx dy〗 And assume the following bilinear interpolation shape functions are used to discretize the spatial geometric variable x and y: N1= ¼ (1-z)(1-e) N1= ¼ (1+z)(1-e) N1= ¼ (1+z)(1+e) N1= ¼ (1-z)(1+e)
Where -1 ≤ z , e ≤ 1 for the local coordinates, z & e Determine the value of g using Guass quadrature numerical integration method. Explain any similarity or difference between your answer and the exact solution.
