ICEM里划分的网格,网格质量0.2,网格数量500万,无周期性边界,就是一个简单的阀件外面加了一个流体域,流体域体网格设为128,阀件设为64,阀体表面设置面/壳网格为大都为32,风从流体域进入到阀件的进口,再从阀件中的管道流出,我想算阀件的阻力。 展开

你的这个速度入口是在模型内还是在模型边界上?这个warning的内容是在这个速度入口的part中有两个单元是相邻的,也就是说这个速度入口存在双面网格。这里解释一下,速度入口一定是单面网格,举个最简单的例子就是模型的最外边界,内侧有网格,外侧没有,就是所谓的单面有网格,这样fluent才能正确的定义速度入口。但是你这个速度入口有部分网格有问题,导致了fluent检测到了双面网格,这应该是建模的时候有错误导致了网格拓扑不正确
追问
阀件的进口设置为内部面,外部流体域边界设为压力进口,检查发现是流域的body和阀件的body在用设置局部尺寸大小给体网格加密时,大小设置反了。(目前不知这样的操作为什么会出现这样的warning)
现在发现一个问题:为什么我算的不加流域和加流域,阀件的进出口全压相差250pa,两者有什么区别吗?(介质为空气,边界条件:压力进出口)我初步认为不加流域,阀件进口面压力是均匀进入的,加流域更符合实际情况
