Incorrect imposition of boundary conditions can lead to computational instability, lack of convergence, and incorrect or inaccurate results. Boundary conditions must be specified consistently with various characteristics of the flow, such as the velocity regime at input and output, interactions with viscous walls, etc.

摘要

Incorrect imposition of boundary conditions can lead to computational instability, lack of convergence, and incorrect or inaccurate results. Boundary conditions must be specified consistently with various characteristics of the flow, such as the velocity regime at input and output, interactions with viscous walls, etc.
