Install dependencies

pip install numpy scipy matplotlib taichi tqdm

Workflow

1. Use PIC solver to simulate Landau damping. Parameters are specified in the paper Qin et al. The data will be saved in the folder data_pic.

python pic_solver.py

2. Then analyze the result using the jupyter notebook analysis_pic.ipynb.

Results

The results are as good as a Vlasov solver. Maybe some higher degree interpolation techniques are required.
