你好 我的网格有报错 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. 请问怎么解决
你好,第二步压缩时报错,该怎么解决呢
Bad Material definition in element number 990 instance LAMINATE-1: zero or negative initial dilatational modulus caused by bad material data. Please check your material input and any initial conditions if necessary.

还有一个可能的原因: 子程序忘记加 include 'vaba_param.inc' 这一句,导致变量精度不匹配。 建议使用单精度计算看看还会不会有问题

zero or negative initial dilatational modulus 提示表示奇异矩阵,主要是提示输入的材料参数可能有问题,导致计算出的弹性模量、剪切模量或者泊松比出现负值,检查一下材料参数即可。
