3、果取none，就是对计算结果不进行光滑处理。
如果取average，有simple,advanced等几种方法，其中simple和advance的结果差异非常小，difference的应力结果通常会比simple,advance的要大一些，一般使用simple就可以了。
取平滑和不取平滑，应力结果差别比较大，但对位移结果没有什么影响。
........................................精品资料通常情况下，把应力结果进行光滑后，应力值会下降一些。
在实际工作中，通常都是取光滑后的应力结果，这样的结果更接近结构的真实受力。SimpleAveraging Simpl
