动网格及UDF实现高速列车交会
研究两辆高速列车交会时应用动网格,边界条件如何设置,以及如何应用UDF实现高速列车的运动,代码应该怎么样写?有没有对这方面比较熟的高手,请求帮助,谢谢大家 建议自己多看看文献资料,毕竟这方面的话,文献上写得会更清楚些,至于UDF,可参考帮助文档。 回复 2 # csuperfect 的帖子对于两辆高速列车交会模型来说,在动网格方法中(Smoothing、Layering、Remeshing)应该选在哪一个呢?另外Smoothing下的参数弹簧弹性系数应该设置多大?急急急,请求指教,谢谢了 Smoothing enables the spring-based smoothing method where the edges between any two mesh nodes are idealized as a network of interconnected springs;
Layering enables the dynamic layering method which can be used to add or remove layers of cells adjacent to a moving boundary based on the height of the layer adjacent to the moving surface in prismatic mesh zones;
Remeshing enables the local remeshing method in which the cells that violate the skewness or size criteria are agglomerated and locally remeshed. 其实楼主还是没太注意在进行列车交会模拟时,常用的是滑移网格法,其得到的结果可信度要高于动网格法的 回复 4 # csuperfect 的帖子
额,能否用中文呢,我英语很烂,谢谢主任
