Conservative Charge and Current Deposition on Nonuniform 3D Cylindrical PIC Meshes with Residual Self-Field Diagnostics
New research details advancements in particle-in-cell simulation techniques for fusion plasma modeling.
Researchers have developed a novel charge and current deposition scheme for particle-in-cell (PIC) simulations on nonuniform 3D cylindrical meshes.
The method utilizes cylindrical-volume weighting and nodal control volumes to ensure accuracy and control numerical self-fields, crucial for modeling fusion plasmas.
Tests show improved charge recovery and reduced current-density errors compared to existing methods, with face-centered electric fields yielding the smallest residual self-fields.
