12 nodes are used more than once as a slave node in *TIE keyword. One of the *TIE constraints at each of these nodes have been removed. The nodes have been identified in node set WarnNodeOverconTieSlave.

16752 elements are distorted. Either the isoparametric angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted.

16 nodes have dof on which incorrect boundary conditions may have been specified. The nodes have been identified in node set WarnNodeBCIncorrectDof.

求问大神，该如何解决啊？

前面几个警告如果对模型收敛性没有影响的话可以忽略不计，我觉得主要是单元扭曲的问题，16752个单元扭曲，可以在单元集合中看到，建议重新画网格，另外边界条件也需要调整
