# partial differential equation

See the attached file.

D(phi)/d(tau)+d(phi)/d(chi)+d(phi)/d(epsilon)+1=0

Boundary conditions:

phi as a f(chi,epsilon,0)=0

phi as a f(0,epsilon,tau)=1

phi as a f(chi,0,tau)=1

Solve the PDE..... solution and explanation would be fine

Any method to solving the solution would be fine

(numerical or analytical).
