LS-Dyna在提交运算时出现k文件包含的ID号之外的Unattached nodes? 20
Ls-dyna出现了如下的警告
*** Warning 40378 (SOL+378)
*******************************************************
* - Warning - *
* 4 Unattached nodes have been detected. *
* These nodes do not belong to Lagrangian *

*** Warning 40379 (SOL+379)
UNCONSTRAINED Thermal Node data
The following nodes were not attached to any THERMAL
element and have been automatically constrained out.
32144 32143 32142 32141
*** Warning 40538 (SOL+538)
Slave node is not constrained
no segment was found in bucket sort.
tied interface # = 2
slave node # = 241
这个警告是在使用对称面的时候出现的,当不使用对称面时可以计算且不会弹出对应的警告
对k文件进行了节点号搜索,发现k文件中节点ID号最大排到32140,至于32141等报错的节点ID在k文件中也没有提及,这几个点是怎样产生的呢?或者是说,LS-Dyna的SPH粒子不支持对称下的热分析?
