Hi everybody
I need help to solve the following problem in finite element
A field variable f(x,y)=x? y is defined over a rectangle domain
?={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= ? (1-z)(1-e)
N1= ? (1+z)(1-e)
N1= ? (1+z)(1+e)
N1= ? (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.
Please advise
Thanks to all

My apologies but there's a no homework policy on this list -- good luck! Michael

We don't do homework on this list. Especially homework that has essentially nothing to do with R. -- Bert
