我算的是一个换热器，全部管束精细建模的，壳侧是钠，管侧是沸腾的水，水侧就没有建模，用udf算完传热后加到管壁上。因为有两千多根管，需要分别算每个管子的传热，我是先根据管子的位置算出来它的编号，存到udmi15里边。在算的时候，先识别编号，把这个编号的管子的所有面存到一个集合里边，再遍历这个集合。之前调试的时候有一些内存使用之类的报错，调了之后不报错了，但是一步都算不动，不知道怎么调试了。
附上我的udf，有没有大佬给点建议？Boiling(5).c

有一个管束模型，是从底面生成面网格后直接拉伸成体网格的，有两千多个管子面，在同一个part里边。计算的udf里边需要分别累积每个管子的传热量，所以需要给这些管子分别设置边界条件。网格量2亿，icem里边点起来都很卡，所以手动设置不太现实，有没有其他方便一些的方法？因为管束中间还有一些支撑结构，所以用其他软件扫掠也没有办法画网格。

@李东岳 李老师好，是我问的。最近在做一个项目，网格无关性一直做不好，有时候网格数量多了反而还偏离了

还有一点，在无关性分析中需要保持所有的网格达到相同的收敛标准吗？网格数量增多之后收敛性有可能变差

比如说有一个多孔板模型，开孔部分设置较小的面网格，其他部分设置较大的面网格。在做网格无关性分析的时候需要分别调整两个尺寸设置吗？还是只看总网格数量即可？
另外，边界层层数设置也会影响网格数量，这个应该怎么考虑？

请问下找到方法了吗？我也遇到相同的问题了

各位同仁好，最近在算一个节流装置的阻力系数，标准值是1350，但是fluent不管怎么加密网格改湍流模型，算出来都在1500左右，cfx随便画个网格用sst算出来就是1350，请问有没有人了解这是什么原因？请各位大佬不吝赐教。
