  • udf官方算例
    udf官方算例,有助于大家更好地掌握udf的使用。UDF并不是什么神秘的东西,然而在地球人的眼中,凡是与编程相关的工作,总是认为有点儿高大上罢了。其实UDF程序的编写绝对只是个体力活儿。Fluent是一个通用软件。所谓的通用软件,意思就是说啥事儿都能做。能做流动,能做传热,能做化学反应,能做多相流,貌似与NS相关的内容都能做。然而,无所不能往往也意味着不甚精通。软件为了满足其通用性,无疑在各种参数的选取上偏于保守,比如说各种求解算法、各种模型参数,为了保证其收敛性和鲁棒性,必然会存在舍弃精度的做法。因此,通用的软件常常难以满足高级人士的计算需求。作为商用软件,Fluent自然不愿意损失
