Coupled algorithm for investigating microplastics’ impact on fish using unstructured grids

Published in China National Invention Patent, CN 119558222 (Granted Dec. 5, 2025), 2025

This patent stems from research conducted with Prof. Lai Zhang on computational modeling for environmental science.

Key technical details include:

  • Construction of complex unstructured grids in Matlab, with over 17,000 nodes and 99,000 connections, to represent the marine environment.
  • Development of a novel advection-diffusion coupling algorithm to simulate PDE equations that model the dynamic migration of microplastics.
  • Application of improved ecological models (Lotka-Volterra) to assess the dynamic changes in fish populations resulting from microplastic exposure.
