Numerical PDE HW 8

Finally more Finite Element (FE) stuff

Repeat HW5 for the following mixed boundary condition on our quarter circle grid (this time leave the radius three), make a decent plot of the solution, and report the value at the point {0,1.5}.

u = Sin[x1] on the x1 axis.

((∂u)/(∂n))=0 on the x2 axes

u=Sin[3]+Sin[x2] on the outside of the circle.

Repeat HW5 for the following mixed boundary condition on our quarter circle grid (this time leave the radius three), make a decent plot of the solution, and report the value at the point {0,1.5}.

u = Cos[x1] on the x1 axis.

((∂u)/(∂n))=Sin[x2] on the x2 axes

u=Cos[3]+Sin[x2] on the outside of the circle.
