In the context of the Georgia Institute of Technology, MATH 6644 (cross-listed as CSE 6644) is a graduate-level course titled Iterative Methods for Systems of Equations. It focuses on numerical solutions for large linear and nonlinear systems, which are essential for engineering and scientific computing. Core Topics Covered The Student Experience Taking Math 6644 is often

1. Is it blowing up? Your ( \Delta t ) is likely too large (explicit instability).
2. Is it oscillating? You might have negative diffusion (upwinding error) or an eigenvalue near the imaginary axis.
3. Is it damped too much? Your implicit method (Backward Euler) is stable, but it introduced numerical diffusion—the "stability tax."
