Implicit (Backwards) Euler's Method

  1. Oct 2, 2011 #1
    How would one go about solving for one variable for an implicit Euler's method such as this:

    I am completely lost...all I know is the value of U and dT

    Un+1 = Un + (dU/dT)|n+1dT
    Vn+1 = Vn + (dV/dT)|n+1dT

    No matter what numerical integration technique you use, you are going to need some function f(U,t) that calculates dU/dt.

    Regarding implicit Euler, do you know how explicit Euler works?
