I have a grid where I know the velocity v[x,t] in each node. What I want
to do is to graph the characteristic equation dx/dt=v using the velocity
values. I couldn't graph this equation correctly with Mathematica. In my
problem, if v->0 the characteristic curve has to be vertical and if
v->infinite the curve is horizontal.
o (x2,t2)
/ |
/ |
/ | 1 This is a picture of my problem. I
know the velocity at the point (x1,t1)
/ | but I don't know the point
(x2,t2).
/ |
(x1,t1) o ------o
1 / v
Do you think that I can graph the characteristic curves for this problem
using Mathematica??
I really appreciate your help....
Thanks
