在对一个复合材料结构进行振动分析，单独运行模态分析无问题，加上PSD激励谱求解随机振动，报错，求高人解答，万分感谢！
是否为求解谱设置错误？但用其他模型没问题。

前段时间做一个带有DO循环语句的瞬态热分析，分析了一年的时间，然后提示了错误“Number of results on results file exceeds maximun of 1000. Maximum may be increased with /CONFIG command” ,按照语句提示，我添加了“/config,nres,5000”,但是还是出错了，后来看了一些别人写的一些命令流，才发现这是因为这个语句放的位置不对，我将它直接放在了“/solu”里面了，虽然“/config,nres,5000”语句看似是设置结果的语句，但是必须放在求解语句之外，一般放在“/solu”上一行，或者放在命令流开头。希望给刚学APDL的朋友一点借鉴！不要犯这种错误。

A slope direction of X is invalid. Slope direction of X will be used.什么意思啊？

在线弹性屈曲分析的时候遇到这么一个err：：：A term of constraint equation 362 is not defined,most likely due to
a displacement constraint on this or an adjoining constraint equation，这是什么原因呢？

这个对计算没有影响，只是你有些约束加在了节点上，有些加在了面上、线上，建议都加在节点上

请问有谁知道填筑路基分层加载时加载速率怎么设置？
，这里的time step及minum time step要怎么设置才与时间有关呢？
求大神指导！

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. 结构发生大变形，原因是啥

我做了一个结构静力学分析  ，在进行mesh网格时最后出现这条错误提示：
Error: A mesh could not be generated using the current meshing options and settings. Hint: The problem geometry areas might have been highlighted. Switching to wireframe mode may make them more visible.
