Question: How can i plot constant stream lines with the help of maple code?

Hi all

 
i am solving a system of four coupled differential equations using bvp[midrich]approach..

The code i am using is in the attach files 

command is like

> A1 := dsolve({bc, eq1, eq2, eq3, eq4}, numeric, output = array([seq(0+0.5e-2*i, i = 0 .. 200*bb)]), method = bvp[midrich]);

with(plots)

interface(displayprecision = 7)

b := 11; bb := b-1

g(eta):=Int(h(eta),eta);

c1 := [x*f(eta)+g(eta), eta]

> contourplot(c1, x = -10 .. 10, eta = 0 .. 10, contours = [-2, -1, 0, 1, 2], 0 .. N);

note that f(eta) and h(eta) are the two unknowns ftns in eq 1 and eq2.

I have two questions

1) i need to plot stream lines for the function psi:= x*f(eta)+g(eta) for some constant values of psi like psi:= -2,-1,0,1,2 etc where we have 

g(eta):=gamma*int(h(y))
f(eta) and h(eta) are the two unknowns from eq 1 and eq 2.

2)using this command A1: although i can obtain numerical data in matrix form but how can i select a particular dependent variable and its column entries (entire) from this num data and export it to graphical software like Tecplot.
