用abaqus做umeshmotion磨损仿真出错，刚开始就发生错误，错误如下

54 elements in the adaptive mesh domain are distorting so much that they turn inside out. The elements have been identified in element set WarnElemAdaptMeshDistortStep1Inc1.

54 ELEMENTS WOULD HAVE EXCESSIVE DISTORTION AS A RESULT OF MESH  SMOOTHING.  
SMOOTHING IS ABANDONED FOR THIS INCREMENT.

MESH SMOOTHING IS ABANDONED, DUE TO ILL-FORMED ELEMENTS.

ADAPTIVE MESH CONSTRAINTS CANNOT BE APPLIED IN THIS INCREMENT.  CONSIDER RERUNNING THE ANALYSIS WITH SMALLER TIME INCREMENTATION IN THIS STEP.
