我也报道一下，在南航读研呢，请各位前辈传授工作应验，向你们学习，正好有问题请教：我在做课题，也是ansys分析基坑开挖的问题，用plane42模拟土体，beam3模拟桩，combin14模拟支撑，用dp准则，涉及土的膨胀角问题，密砂及超固结土有膨胀角，一般土体发生剪缩，膨胀角设置为零，可是我的命令流一旦膨胀角为零，就无法进行，提示以下错误：One or more elements have become highly distorted. Excessive distortion of elements is usually a symptom indicating the need for
corrective action elsewhere. Try incrementing 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 behavior of materials, contact pairs, and/or constraint equations. If this message appears in the first iteration of first substep, be sure to perform element shape checking.。希望前辈指点一下，谢谢啦！！！！十分感谢，困惑我很久了，我的E-MAIL:zhaochun0184@126.com谢谢啦 |
