dyna爆破模拟里的这几个错误是什么原因
浏览：4202 回答：7
我做书上的例子，遇到几个错误
1、Missing *ALE_MULTI-MATERIAL_GROUP definition for
ALE multi-material formulation 11. All parts defined with
ELFORM=11 will be taking material properties of the first
defined ELFORM=11 *PART
2、
*** Error 10246 (KEY+246)
line contains improperly formatted data
reading *SECTION card.
At line# 91398 of file
这个我照书上多加了个section_solid_ale，就出现这种情况
3、
*** Warning 10302 (KEY+302)
CHECKING MATERIAL INPUT Part ID= 1
The default hourglass properties of the following
ALE part are being modified to avoid unnecessary
application of hourglass forces.
Resetting coefficient qm=1.0e-6.
PART ID 1 with
MATERIAL ID 1 and
EOS ID 0
This is PART 1 in the order of input.
谢谢啦
1. 单元算法你选择了多物质算法，就必须要定义*ALE_MULTI-MATERIAL_GROUP
2. 不要按照书本的来，由于版本的更新，有限书籍的用法过于陈旧，一切以同步的k文件manual为准
3.这个warning 不用管，也可以在*part中手动设置粘性沙漏控制！
