Criticality calculation of an homogeneous finite reactor

  1. Jan 20, 2016 #1
    Please,I am working on the criticality calculation of an homogeneous finite cylindrical reactor core using four-group diffusion equations. I have been able to discretize the multigroup diffusion equations using the finite difference method(FED). But

    I am stocked on the iterative method to solve the linear equations using matlab. Thanks

    I'm assuming one is doing this in a 2D geometry.

    Has one studied an example of a 2D 2-group system?

    yes sir, it is a 2D geometry which entails r and z, but most examples i have come by are mostly 1D and very few 2D(x and y) 2-group system

    please, I wanted to upload my sets of equations on the forum, but I couldn't. How can I display my set of discretized equations

    please I am stocked on how to use an iterative method(gauss-seidel or SOR method) to solve the linear equations using matlab with the above attached pdf document. Thanks

    I think you will have to program the Gauss-Seidel method yourself. I recall that it was straightforward in FORTRAN, but should be doable in MATLAB.

    Yes I want to programme it using the Gauss- Seidel method, but i need an algorithm or the calculation strategy well explicit that I can use to calculate the criticality calculation. Thanks
