[求助]求解出错问题

计算未完出现“One or more elements have become highly distorted.  Excessive<br>distortion of elements is usually a symptom indicating the need for<br>corrective action elsewhere.  Try incrementing the load more slowly<br>(increase the number of substeps or decrease the time step size).  You<br>may need to improve your mesh to obtain elements with better aspect<br>ratios.  Also consider the behavior of materials, contact pairs,<br>and/or constraint equations.  If this message appears in the first<br>iteration of first substep, be sure to perform element shape checking.”出错信息，如何解决？<br>

网格有问题

<P>这个问题我也遇到过，当时我用的是四面体网格，在变形过程中由于方向问题使网格形状发生变化，出现distorted的情况。如果你也用的四面体网格建议划分成规则的六面体网格再试一下。</P>

"One or more elements have become highly distorted"<BR>对应于你的所用的单元而言, 网格划分的不好．导致过度的扭曲．
