prism_2
Overview
This project is Karman vortex simulation around square prisms. Poisson equation is solved for the analysis of the pressure field, and Kawamura-Kuwahara scheme is used for the analysis of the velocity field. Pressure field is visualized by using python3.6 + matplotlib (details below).
