提交任務失敗，提示的錯誤信息如下 The volume of 4 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. 我檢查了網格質量是沒有問題的，覺得應該是節點號編排的順序出現了問題，但是不知道應該怎么修改，是重新畫網格嗎？下圖是問題網格的集合，請各位大神不吝賜教
