Solution of General Partial Differential Equations
This script gives the numirical solution of PDE of the form
a1*Uxx + a2*Uyy + a3*Uxy + a4*Ux+ a5*Uy + a6*U=f(x,y)
where a1,a2,a3,a4,a5 and a6 are functions on x and y or constants. The solustion is carried by SOR iteration method
Number of intervals =
Coefficient of Uxx a1(X,Y)=
Coefficient of Uyy a2(X,Y)=
Coefficient of Uxy a3(X,Y)=
Coefficient of Ux a4(X,Y)=
Coefficient of Uy a5(X,Y)=
Coefficient of U a6(X,Y)=
the RHS f(x,y)=
u(X0,Y)= u(Xn,Y)=
u(X,Y0)= u(X,Yn)=
Lower X0= Lower Y0 =
Upper Xn= Upper Yn =
Output format :
This is an example for output data in graph mode of boundary value problem
Δ U(x,y)==-x*y, U(x,y)=0 at all boundaries.
