system of partial differential and differential equations
Hello, I´m trying to solve a system of partial differential and ordinary differential equations. The system of equations is described by the following two equations: du1/dt=A*du2/dx du2/dx=B*(u1-u2) u1 is only dependent on the time t; u2 is dependent on the two variables time t and position x.
