一个警告信息产生的纠结~

suking_love

警告信息内容：Both solid model and finite element model boundary conditions have been applied to this model.  As solid loads are transferred to the nodes or   elements, they can overwrite directly applied loads. 1、这到底是什么意思？指的是我哪些地方错了？ 2、solid model 和 finite element model有什么区别啊？ 感谢各位的热心相助了~
