ABAQUS 怎么加载对流换热系数
CONV VALUE is typically the film coefficient and VALUE2 (below) is typically the bulk temperature.If VALUE = -N,the film coefficient may be a function of temperature and is determined from the HF property table for material N [MP].The temperature used to evaluate the film coefficient is usually the average between the bulk and wall temperatures,but may be user-defined for some elements.l
上面是abaqus的帮助文档的内容,个人以为大概意思是
（1）hf是材料的对流或模系数,而Conv的值一般是膜（或对流）系数的值,若值为－N,则选取材料的HF值,这是原文帮助的意思,说白了,CONV的值可以是材料的对流或模系数,也可以是其它数值；
（2）理论上讲,一般地两个值是有关系,即Hf应该等于CONV,但也有特殊情况,此时两者有可能有差异,因此,设定两个量定义,以使程序更加灵活；
本人也没有做过热对流的模拟,你可以去仿真论坛中去找找.
