另外,不建议不同的算法采用共节点,为了对比说明几种算法的不同,模拟中采用了不同的算法共节点,所以会有以下警告
*** Warning 302 (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 1
This is PART 1 in the order of input
*** Warning 302 (KEY+302)
CHECKING MATERIAL INPUT Part ID= 2
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 2 with
MATERIAL ID 2 and
EOS ID 22
This is PART 2 in the order of input
*** Warning 5123 (SOL+123)
There are 2107 nodes shared by ALE eleform 11/12
and other Non_ALE eleforms.
由于图较大,采取了分段压缩,可以下载查看。从图中可以看出,后来的网格网格变形很大,到68us时,出现了速度无穷大的现象,因此也说明了LAG算法和共节点不适合大变形的模拟。 d3plot_gjd_kq_lag_ale_001.part1.rar(2 MB, 下载次数: 0, 售价: 2 点体能)
