一直不懂这两种边界条件的区别,在帮助文件中看到这样一段话:
This setting is less stable than the total pressure condition because it weakly constrains the momentum which passes through the boundary. It is constrained only by transverse stresses. It is therefore a useful condition to obtain a fully developed velocity profile but is also less robust than the total pressure condition.

请大家帮忙解释,谢谢
