请问下除了用dnsFoam,还有别的求解器适合做直接数值模拟的么?
为什么要用dnsFoam, http://dyfluid.com/icoFoam.html
@李东岳 李老师好,simpleFoam和pimpleFoam的层流计算是不是也可以认为是直接数值模拟?
@zhouxu pimpleFoam可以。但是大家说的直接模拟,一般需要非常高的精度,openfoam这面上不到那么高精度,需要谱方法之类才行。所以openfoam、fluent做直接模拟,效果会差很多
@李东岳 好的 谢谢李老师
@李东岳 东岳老师您好,我了解到openFoam因为精度问题,做的DNS只能被称作quasiDNS,那么自带的dnsFoam和不加湍流模型的icoFoam/pimpleFoam有什么区别么?
