fluent求解器中气体浓度的单位？

rcy060112

求教！！设置CO和air混合组分，在solve-initialize-patch里面设置CO初始浓度，value下面对应的应该填入的浓度的单位是什么？以及监控点或线里面要显示的监控处的浓度选择   mass  fraction of或mole  fraction  of  分别检测的浓度是什么含义？该怎么统一换算呢？

Mass fraction of species-n    (in the Species... category) is the mass of a species per unit mass of the mixture (e.g., kg of species in 1 kg of the mixture).
Mole fraction of species-n    (in the Species... category) is the number of moles of a species in one mole of the mixture.

所有的用到的参数的定义以及单位查询请参考fluent帮助文件
