error:Meshing of volume 5 has been aborted because of a lack of memory. Closed down other processes and/or choose a larger element size, then try the VMESH command again.Minimum additional memory required=853MB
划分的网格太细了,内存不足。建议将模型划分为几个部分,分部分进行划分,可以减少内存使用 NO.0031
在MAC文件中中文的注释前的感叹号必须是英文格式下输入的,如果是中文格式的,宏文件运行会出错 NO.0032 ring model建立时候遇到的Brick element 4731 has an aspect ratio of 1000, which exceedsthe warning limit of 20. 单元网格奇异,跟我上面贴的一个帖子差不多。
网格划分的时候如果单元的两边长度差距比例超过20就会有该错误 不过一般的情况下这个错误也可以不理他 NO.0033
clear is not a recognized GEGIN command,abbreviation,or macro. this command will be ingored.
那是因为打开了前处理,求解或者后处理, 先用FINISH命令,再用CLEAR就可以了 NO.0034
solid95单元建立的混凝土单元,分网之后(方法是:先在面上指定单元尺寸,自由划分,然后vsweep分体)弹出警告:solid95单元只被推荐用于低应力区域. 然后在求解过程中又出错误:(一加重力就出这样的错误) *** ERROR
*** CP= 1971.078 TIME= 20:41:10
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.
第一个警告一般都会出现的,只是提醒你solid95单元只被推荐用于低应力区域。没有什么问题的。
第二个error是单元高度扭曲。 按照它提醒的做,把载荷子步变多一点有时候能够解决问题。如果不行就检查网格划分得是不是比较好。 NO.0035
Large negative pivot value ( -8.419662714E-03 ) in
Eqn.system. May be because of a badtemperature-dependent material property used in the model. 这种错误经常出现的。一般与单元形状有关。 NO.0036
Both solid model and finite element model boundary conditions have been applied to this model.As solid loads are transferred to the nodes or elements,they can overwritte diretly applied loads.
主要是在一些边线的节点会有载荷,边界条件的约束同时施加在上面,一个会覆盖掉另外一个 一般忽略该警告 NO.0037
solid model data is contaminated
实体模型被污染了(布尔操作中经常出现)
原因就是布尔操作中出现运算错误,实体模型被污染。 解决办法:1、修补模型。 2、最好的还是重新建立模型。 关于这个,还有一种方法是将模型用write命令写出来,然后用read
命令读进去就好了 NO.0038
建了一个三维结构的模型 模型中土体材料使用ansys中的dp模型,可是每次一使用dp模型时,计算怎么也不收敛,我用mcheck命令检查了一下单元,出现了类似以下的好多warning:

Element 3526 node 5851 is part of at least 2 distinct sets of exterior
element faces. This may indicate that the attached elements are

Element 3526 node 5851同时是 两个(及以上)单元外表面的一部分。这意味着,相互连接的单元式以一种不寻常的方式连接起来的。 也就是说,网格质量过差,导致不收敛。、需要把网格划分好一点 NO.0039
