Virtual.lab计算报错

在Virtual.lab中参照风扇噪声计算径流式压气机噪声，在定义扇声源的时候提示“With the current load function set settings no load or response function will be sued from the data source. Please check that function class and physical types of the functions from data source are compatible with the current load function set settings”，求教这指的是哪里不对，或者说fan这个噪声计算就不适用于其他叶轮机械
