在进行了随机振动分析后,进行Post26 的分析,在我选择节点进行谱分析的时候 一直会弹出一个警告: A different set of data points exits for the new variables than can be stored with the previously stored data points. This may be OK if STORE,PSD has been issued. Points that do not match are ignored. Issue STORE,NEW to stroe all data points.
这是为什么呢?
