最近分析結構時間出現一下報錯：

“At least one contact pair has no elements in it.  This may be due to mesh defeaturing.  Please modify defeaturing settings which are accessible on the Mesh object.   You may select the offending pair via RMB on this warning in the Messages window.”

幾經折騰后查到可以試試把contactallowempty設置為1。但是研究了半天還是找不到這個如何去設置，不知道有沒有哪位前輩能指導一下如何設置，或者能夠很好地解決這個問題。

謝謝啦
