@light 在 ICEM敞开边界的网格如何绘制 中说:
大多数文献模拟都对出口和进口不设置具体边界。但是这样我的几何体就不封闭了,无法正确生成网格,这种情况该怎么
你是肯定要设置边界的啊,不设置边界没法计算哟

@东岳 Analysis of a frictional–kinetic model for gas-particle flo
教授你好!
正如我上面列的文献,原文如下(Simulations of particle discharge from a 2-D rectangular bin, 8 cm wide, 100 cm high and open at the top, were performed. The width of the central orifice at the bottom varied between 1.4 cm and 2 cm. A schematic of the simulation domain is shown in Fig. 3a. A 5-cm high region below the bin was included in the domain so that a boundary condition was not required right at the exit of the bin. The symmetry of the solution about the vertical centerline of the bin was assumed.)
这不就是说进出口是没有具体的边界的吗? -
本人按在实际出口下方5cm处建立一个出口边界,实际出口则设为内部边界,最后调整参数,得到了与文献相似的结果。感谢各位的帮助!!
