Neutron Diffusion Solution for the One-Dimensional Steady State Equation.

To Do

• Block submatrix solve of Ax = b --> prevent building A (Gauss Seidel)
• Fix dictionary problem when the same material is used more than once in a problem
• Create a graphing class (inheritance)
• Time Dependency
• All the PyTest functions
• Be able to run 618 group problem with I = 400

Reference

• computational_engineering.py: Reference code from Ryan G. McClarren's book "Computational Nuclear Engineering and Radiological Science Using Python".
• diffusion.py: The main code currently used with C-function speed-up.
• diffusion_lambda.py: The original multi-group diffusion problem written in python.

Functions for Graphing Class

• Convergence vs Iteration
• Critical, subcritical - integrate flux over energy vs position
• Different fixed spatial points flux vs energy
• Theoretical memory vs Rank (error Keff)
