Solution to Complex Grinsburg Landau Equation

[Yash-Deodhar]

Hello,

For an old homework assignment I had to write C code to numerically solve the Complex Ginsburg Landau equation (please refer to https://github.com/Yash-Deodhar/Complex_Ginsburg_Landau for the exact question and C code) . The computational bottleneck for the algorithm is the multiple Fourier Transforms required at each timestep which accumulate to tens of thousands of times per run. This made the problem infeasible in python. However, by using the host APIs in nvmath you can now run the algorithm for large times.

The link to the python code is: https://github.com/Yash-Deodhar/Complex_Ginsburg_Landau/tree/main/nvmath

The above link also contains a file generate_plots.py which creates the .mp4 videos of the evolution of the argument and and absolute value of the solution to the equation.
