在Ansys中,solid95单元建立的混凝土单元,分网之后（方法是：先在面上指定单元尺寸,自由划分,然后vsweep分体）弹出警告：如附件。solid95单元只被推荐用于低应力区域．然后在求解过程后,一加重力就出这样的错误,又出错误：如附件错误。这是什么问题？
***ERROR *** CP= 1971.078 TIME= 20:41:10 One or more elements have become highly distorted.Excessive distortion of elements is usually a symptom indicating the need for corrective action elsewhere.Tryincrementing the load more slowly (increase the number of substeps or decrease the time step size).You may need to improve your mesh to obtain elements with better aspect ratios.Also consider the behaviorof materials, contact pairs, and/or constraint equations.If thismessage appears in the first iteration of first substep, be sure to perform element shape checking. 使用KinematicPlasticity 准则在某个节点处不收敛。 要不换一个准则试试看。
