欢迎讨论,温度场计算的时候,换网格,结果差别大不大?

我这个是计算激光焊接温度场,单元,热源参数,体积,材料参数不变,下面是我2个不同的网格划分方式,命令流和图形给出,请大侠们指教
第一个:

请大家过来看看啊,我很困惑

Re:欢迎讨论,温度场计算的时候,换网格,结果差别大不大?

我把第二个的功率系数改到0.7,最高温度1500度,远低于第一个功率系数0.27的3500度

Re:欢迎讨论,温度场计算的时候,换网格,结果差别大不大?

问题得到解决,原来是把加载方向搞反了,以上命令流可以计算

里面取值怎么取的！！！谢谢！！！

楼主能不能把椭球表函数对应的公式的表达式贴出来，我采用椭球加载，怎么会在求解时温度非常高呢？

新元素 发表于 2007-5-31 14:29:36

你的命令流我走了一遍,发现你的热源一直在坐标原点,并没有实现热源移动,能否给解释下,现在把运行的结果贴下

速度方向加反了，改下速度的符号就可以了

改下速度的符号,运算时载荷加载不上去呀~~
请问LS 试过了吗???/

那位热心人给解释下!:'(

双椭球热源采用的表格加载看不懂怎么和公式对应起来

下天雄 发表于 2008-11-21 11:20:19

请问图中的网格是什么类型的网格啊？

wxpand2004 发表于 2010-4-13 16:00:44

好像是局部细分的吧
