View Full Version : Coupled First order PDEs

I am looking for a method to solve coupled first order PDEs in following
form:


\frac {\partial u1} {\partial x} = f(x,t,u1,u2)



\frac {\partial u2} {\partial t} = g(x,t,u1,u2)


Subject to prober BC and IC. and consider:


u1=F(x,t)


u2=G(x,t)


I am looking for both numerical and analytical methods. Please note F and G are both nonlinear and I am not sure if we could find an analytical solution. The method of characteristics can give us a solution for quasi linear and linear sets.
