Newton-Raphson Iteration in Transient Thermal Analysis

  1. Dec 8, 2009 #1

    I have been quite confused about this for sometime now. It has not been mentioned clearly in the books/references that I have looked into.

    In transient thermal analysis using FEA with implicit scheme or the Crank Nicolson scheme, are there Newton Raphson iterations based on the residual vector in every time-step?

    Any insights or suggestions are highly appreciated.

    The Crank-Nicolson is a finite difference method, not a finite element method.

    Have you checked your FEA programs help manual?
