我是從mimics的inp文件格式,已經進行了體網格劃分,在3-matic和abaqus中檢查網格質量均爲經過,可是分析做業提交後仍然出現了下列的錯誤:node
The volume of 2 elements is zero, small, or negative. Check coordinates or node numbering, or modify the mesh seed. In the case of a tetrahedron this error may indicate that all nodes are located very nearly in a plane. The elements have been identified in element set ErrElemVolSmallNegZero.ide
解決方法嘗試的有:post
1.從新進行零件的網格劃分,並減少單元尺寸,嘗試避開該區域的較差網格,可是沒用,仍然出現該錯誤;this
2.在abaqus中進行網格檢查,無錯誤,可是有許多警告的單元,創建一個set集合,囊括全部的警告單元;而後在mesh截面裏面刪除該集合,結果仍然出現錯誤;spa
3.從錯誤文件中建立顯示組,顯示錯誤單元,經過query查詢該單元的單元序號,而後在inp文件中進行修改,將該幾個單元創建集合:blog
*ELSET, ELSET=ES_erorElement
42430,47269(這些是問題單元的單元序號)element
從新導入該inp文件,在mesh中刪除該集合的單元,再進行分析,成功解決問題!it
