Translated title of the contribution: An Implementation of Boundary Condition to Poisson Equation for Complex Geometories on Voxel Method

Research output: Contribution to journalArticle

Abstract

Cartesian grid method has higher availability for actual problems of design as First Order Analysis. Especially, simple block approximation is of great stability at the grid generation stage. In this case, arbitrary patterns of wall appear in the computational domain where adequate pressure boundary condition should be employed. In this paper, an implementation of boundary condition that is build into the discretized scheme of pressure Poisson equation is proposed. This method eliminates the difficulties such as the reference points that have multiple value of pressure effectively.
