CFD Discretization Help Needed

  1. Jul 14, 2012 #1
    Hi guys I was wondering if anyone on here could help me out.

    Essentially I am trying to build a higher order cfd code and struggling to work out where to start, I’m trying to build it using polynomial fitting so here’s my problem.

    Taking my domain as;

    x=0---------------------1/3 --------------------2/3------------------x=1

    So I’m wanting to fit a 3rd order polynomial however I’ve not really done much polynomial fitting since A level so I’m quite stuck, here’s what I have,


    Taking the infomation from the domain I can get the four equations





    My problem is that there seems to be two many unknowns can anyone help
