ansys非線性分析不收斂，求大神解答？
麻煩各位幫我看看為什么計(jì)算結(jié)果不收斂，這個(gè)模型是在模擬拉索錨固區(qū)受力，很簡(jiǎn)單的模型，最后總是提醒：
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.
不知如何解決，命令流如下，需要導(dǎo)入截面，無法上傳還請(qǐng)見諒。
