@李东岳 谢谢东岳老师的回复。这个cloud的类型是在KinematicCloud.H 中对cloudType的一步细分。
//- Type of cloud this cloud was instantiated for
typedef CloudType cloudType;
//- Type of parcel the cloud was instantiated for
typedef typename CloudType::particleType parcelType;
//- Convenience typedef for this cloud type
typedef KinematicCloud<CloudType> kinematicCloudType;
无论我保不保留这个,都显示一样的error。这个expected primary-expression before '.' token是什么意思啊?少了什么吗?
